If I could leave zero stars, I would. This is the first review I've ever written -- not because I'm one to complain, but because the level of service I received at this shop was unacceptable and needs to be addressed. I brought my boat in to have speakers installed and the gauges repaired, which were not functioning. After a diagnostic, I was advised to replace the impeller. I agreed, thinking it made sense to get everything done while the boat was already in the shop. When I returned to pick up the boat, the total cost was significantly higher than what I was originally quoted -- with no prior communication or explanation. On top of that, the interior of my boat was returned to me in unacceptable condition: oil and grease stains on the carpet and seats, as if there was no regard whatsoever for cleanliness or care. To make matters worse, after using the boat twice, the speakers and amplifier already stopped working. I reached out, hoping for a reasonable conversation about resolving the issue, only to be told it's not covered. No accountability. No effort to make it right. And as a final touch, a cup holder went missing during the installation -- which they also dismissed. If you're looking to overpay, have your boat treated carelessly, and receive subpar workmanship, this is the place. Otherwise, do yourself a favor and take your business elsewhere. read more

After contacting multiple companies that did not follow through on a simple estimate to repair our boat, we were recommended to go see Eric Koster at J & H Marine by Delta Marine where we purchased our boat. What a fantastic recommendation it became! Eric and Alicia were so incredibly kind and responsive to our estimate request and repair needs. Throughout the entire repair and service experience both Eric and Alicia maintained regular communication on the status of our boat. We were thoroughly satisfied with the fair pricing and the professionalism of the J & H staff that repaired our 2021 Bowrider. J & H has found a new, happy, and lifetime customers! Thank you again J & H! The Martinez family! read more

Contracted with Eric and Kurt from A1 Marine Transmission to do a repower on my charter boat RIPTIDE in 2022. This was a big contract and required all of there different services. From electrical and electronic, mechanical, fiberglass and painting. Work was on time and on schedule. As with any project of this size there were hiccup's but everything was handled in due course. VERY professional and courteous service from everyone. Even when I was being a pain over some details.This is the kind of services that one can hope for. In the interim since the installation there have been some issues of course. Eric has stepped up and went the extra mile(s) to keep things working and able to continue to operate. I could elaborate on more. Bottom line is that I will highly recommend them for knowing the Coast Guard regulations and complying with them. I will HIGHLY RECOMMEND there services for your maratime needs. Thank you to everyone for EXCELLENT services!! read more

Went in for a simple part replacement and to look at why speakers were not working , I was talking to , who someone said she was the service manager that one of the boat's batteries were bad after I explained they were new, they tired to walk back what they had said. Lying to try and sale a new battery is simply disgusting. And what was even more disturbing when I got the boat back the tech had written on the battery that it was LOW volt not bad. After checking on why the speakers were not working the tech found that the wire had a issues and that they could run a new one for $800 dollars so expensive , going to take the boat to a stero shop to get fixed, they did replace a part that was bad Overall I felt the tech did a good job but the manager in charge was not trustworthy and very abrasive and just wanted to rip me off ,, it was a very bad experience and after 23 years of boating I thought I had seen it all. Will never go back unless the part they put in fails. Bottom line: don't trust what they tell you. And question everything read more

J & H Marine - Pic showing low volt , not bad - Boating Near Me - Stockton, California

We own a SeaRay 470 2010 with Cummins engines and Zeus PODs. The team in J&H does an amazing job maintaining our boat. They show up on time. Have all O-rings and alike, so they don't need to wait for parts. Our boat is in Alameda now and they traveled here to replace for us a water pump. I have only good things to say about this team. read more

If you are in the Stockton to Rio Vista region, J and H Marine should be considered for their honest, dedicated and detailed repair work. I had an impeller repair on a Kohler generator, that was in a tight compartment area. The repair was extremely timely and cost reasonable for the work completed. Depending on the work needed there are also associated companies in the same location of Delta Marine that have all been my go to for any repairs or maintenance needed. read more

I took my Parker 2520 to J&H to rebuild the diesel engine that was blown. They figured out the long block needed for the rebuild was no longer made by the manufacturer. I stayed in constant communication with Brent who was coming up with different engine options. We settled on a tier 3 Yanmar LV4 250hp. As the replacement build was taking place, Brent stayed in constant contact with me and gave me daily updates including pictures and videos of what was taking place. Once the build was finished, they cleaned the boat and it was spotless when I picked it up. The day I picked the boat up, it was in the water when I got there. We took it out for a test drive and everything they did was explained in detail. Brent was kind enough to send me the info on what fluids to put in the engine after I left with boat. He even checked up on me later that day when I was out in the boat in another area. This wasn't a cheap project, at least for me, but I would not hesitate to take my boat back to J&H. They are a top notch professional business. Jake Jensen read more

Hi. I had to take my boat into J&H Marine in Stockton. I had an ongoing hydraulic fluid leak on my trim pump. They got me into the shop the next morning and I had my boat back within 24 hours. Their service (thank you Brent!!) was, once again, exemplary! I can't imagine taking my boat anywhere else for service. Five stars all the way! Don M.​ read more

I took my 38' Sea Ray Aft Cabin with Mercruiser twin engines to J & H to have four things done: The port engine would not exceed 2800 rpm, The dripless couplings were leaking, there was a leak in the galley refrigerator and the alternator needed replacing. Due to a lack of coordination with the boatyard, the bottom was painted and the boat was put back in the water without the dripless couplings being replaced. This was due to Kelsey, the customer relations person, being out sick. I did talk to the maintenance manager about the couplings, he was clueless. Kelsey is the key person for J & H. If she is not there, do not bother with them. Eventually they did repair and replace the couplings. The alternator was correctly replaced. The leak in the galley was ignored. The port engine problem was not solved, although they say they are Mercruiser experts. When I left the boatyard, it ran at over 2800 rpm until just before I reached King Island for fuel. Then the port engine would not exceed 2800 rpm. I limped back to San Rafael, where several mechanics looked at the problem. One of them referred me to H & M Marine in Sausalito. They immediately diagnosed the problem as lack of compression in several cylinders, on the port engine, something that J & H did not test for. If you have gas powered engines, I cannot recommend J & H. Instead, if you are in the Bay Area, go to H & M Marine in Sausalito. Charles Stuckey Staff Commodore Marin Yacht Club read more

I don't write many reviews but I had to in this case as Eric, Kelsy, and the entire J&H team are truly rockstars. We have been taking our Formula 370ss to them for about 2 years and they have been nothing less than stellar in their service and follow through. They recently retrofitted the boat with a Dometic Optimus 360 Joy Stick and Sea Station as well as new Simrad electronics and we couldn't be happier with the results. J&H is really a one stop provider for everything your boat needs and they have strategic partners for all non mechanical/electronic work as well. In a world where finding quality and service is difficult J&H really stands above the rest. Many Thanks! read more

I didn't get anything done. Just thought the phone conversation I had with them went really well. The chat allowed me to feel trust and comfort with the business, and my initial thought was to bring my boat in for service and diagnosis. I didn't get her name, but the representative was very helpful. I didn't need to bring the boat in after all, but definitely keeping them in mind for future maintenance needs. I appreciate this business' honesty. read more

Love this place! I had scheduled some upholstery work next door and popped into J&H with no appointment to see if they could do some work on my 30' Chaparral while it was at the docks (trim pump, oil change and what turned out to be an exhaust elbow leak). Even with no appointment, they got the job done within a week (while boat was still having canvas work next door) with reasonable rates and thorough work. Strong rec. read more

I was starting a new business to promote disabled Veterans and Veterans to learn the Marine trade. Eric was nice enough to allow us to place a boat in his lot to get it all blinged out. Even though it took almost three weeks Eric was supportive of our efforts. I encourage everyone to choose J&H Marine for their high quality work and for supporting Veterans. Thanks again Eric.

Called to possibly get in and have our Ski boat worked on. The lady said they were booked till January, so we specifically asked how we get in and she told us to call back mid January! Not good customer service as we are already booking with another company, Lodi Marine, also have to wait a few weeks, but I'm gonna say it'll be worth the wait. read more

After a disappointing experience with another Marine parts supplier I called J&H Marine for help with some problems with my late model cruiser. I am not easily impressed, but the owner Eric, and his team Fred and Nate (and the rest of the guys), absolutely went up and beyond to not only figure out what was wrong, but fix it. Eric gave me invaluable advice and steered me clear of making some expensive mistakes. I know I was a relatively small job for this awesome shop, but they all treated me like I was their most important client! Not only have they earned my trust and business for life, but I made a few new friends in the process! I can not more highly recommend a marine shop than J&H Marine in Stockton! They will take care of you and treat you more than fair. read more

Great customer service. Dropped my boat off on Monday for a transmission leak last week. I needed the boat done for my Labor Day weekend plans. They came though pick the boat up on Thursday 3 day turn around. Outstanding workmanship J&H replaces my transmission lines and replaced all the seals and gaskets. Boat runs like a champ and no leaks. Outstanding customer service and communication HIGHLY RECOMMEND THEM!!!Thanks again J & H for for allowing me to keep my Labor plans with the family. You got a customer for life read more

I recently had an engine over-heating problem while taking my 36' sloop up the San Joaquin River. With luck we barely made it to Tinsley Island. A few years ago I had a heat-exchanger problem in the same place (should I stay olff that river?). Back then I called J & H and they sent our their super mechanic, Dave, who readily fixed the problem fast, skillfully and cordially. Here I was again in the same place with another engine problem. The boat is 15 years old and its small Volvo diesel has performed flawlessly, including doing the Baja Bash. except for these two incidences on the San Joaquin. On the phone again to J & H, first with Eric, captain of the J & H ship then first-mate Fred who scheduled the mechanic to come out to the Island. They were super busy but managed to squeeze me in and out came Dave again. Was I glad to see him! It was a knotty trouble shooting problem but Dave found the culprit and got me going again. J & H gets a super A+ rating from me. Paul Brocchini Carmel, CA read more

Just another marine service taking advantage. I was charged 3 hours of labor for a 20 minute job. Everybody knows it doesn't take three hours to prime a gasoline engine. I ran out of fuel switched tanks and the starboard engine wouldn't re-start afterwards. I was charged separately for a trip visit, then a $366 charge to do a 20 minute job, they are atrocious. Buyer beware, stay away from J&H Marine! To continue, J&H (Fred) reached out time to see what could be done for me to be happy. I replied that I could walk away feeling less taken advantage of if he were to refund two hours of labor. It has been two weeks and I have not even received the respect of a follow up to negotiate a more positive resolution to our business. If you care to spend wisely, don't spend your hard earned money at J&H Marine. read more

I have an older four Winns boat that one of the motors got hot and I thought I blew a head gasket because it wouldn't start these guys diagnose it was just a bad starter replaced the starter and it runs great and they were straightforward and honest Tim came down on Sunday to let me in to pick my boat up being I can't trailer my boat so I can pick it up from their dock Greatwork fair price(nothing about having a boat is cheap ) I will go back if I have anymore motor-or outdrive problems read more

We had a fire in the engine of our Chris Craft Corsair. We contacted Eric at J&H and he helped us every step of the way. He immediately picked up our boat and brought it to J&H Marine. He was in constant contact with updates. He met with the insurance adjuster and backed up our claim. He even wrote a letter to them in support of our case. I have been boating in the delta for 45 years and have never come across a more knowledgable, professional marine repair specialist, I wish I had known about J&H Marine years ago. I have recommended them to my friends and family. read more

Tis just a quick note to say thanks AGAIN... Eric and his team saved us this weekend too. They have been doing it for 15 years - but, this was even more appreciated because it happened over the holiday weekend. Thanks J&H - you've earned super-hero status. read more

I have nothing but high praise for J&H. We just returned (from So. Calif) for a long weekend of boating in the Delta but were concerned that our boat had been in storage (in the Delta Region) for well over 12 months. J&H picked if up from storage a few weeks ago and performed a full service and had it clean and ready for our weekend of family fun - on time and on budget. Although we live out of the area, after several years of having them service our boat in preparation for our trips to the Delta, we have come to rely on and trust J&H to have the boat ready for a fun. A first class business! read more

In my 61 years of life I have never dealt with anyone more incompetent then Eric Koster. His endless lies and failure to finish a contract to repair my boat engine has gone on for 1 year and 7 months, original contract January 2016. They started on my engine later then he promised and when they did show up it was an all night long project to dismantle the engine, with no sleep, how does a person do this without help from Dr#&s. They then came back with one rookie after another. They bent my shaft on my engine, flooded the engine with diesel fuel, admitted after another mechanic had found the error. I would find another mechanic or do the job yourself as these are no one you want working on your boat. They are uninsured and should not be in the boat business. He refuses to finish the contracted work, so I must finish with another mechanic. read more

I had my first misfortune in my Formula Fastech, where a motor cut out on me completely. I came in on one motor to the restaurant we were going to - and I had great good fortune where Eric from J&H Marine happened to park next to me (not sure about HIS good fortune out of work hours). He was just a gracious as could be, did some fast diagnostics on the spot, and came back the next morning with all the required parts and got me up and running. WAY beyond the call of normal marine mechanic duty, but I couldn't be more pleased or recommend him more highly. I was not in any position to argue any bill, but his invoice for this above and beyond call was very fair. Anyone with a boat has probably experienced dicey marine service. I totally lucked out with a great experience. Highly recommended. read more

As a Yacht Broker on the Delta, I have an opportunity to try many different repair facilities with my clients.

Well.. I don't know who this Stephen E. guy is, I do know that I have had a completely different experience! I have had my boat there for the last few months to do a complete rebuild. From the exterior finish, new engines and drives, new wiring, new electronics and appliances, if we didn't replace something I don't know what it was. These guys didn't always know the answer but eventually we created a one of a kind custom boat that must be seen to be believed. Please ask them to show you the boat or call me. I am a real customer that thinks they did an AWESOME job, and I think that I made some friends in the process. read more

The generator was installed Friday and is now working fine, thank you! Seems like all issues are resolved for now.

My wife and I took our boat over to J&H for it's semi-annual service. Oil change, generator, AC, and head. Basically the works. The people at J&H took wonderful care of our vessel. Not only did they handle all the known issues, they check the entire boat and found items we had missed. To add even more praise, each time they encountered and issue they called to inform us and make sure we were in agreement with the next steps to be taken. Overall, best service I have had in years. read more

After having my boat in two different "highly reputable" shops in the Sacramento, and having paid for shoddy and incomplete fixes that they did not seem to be able to find the source of driveline noise...I did some research and decided to tow my boat from Shingle Springs Ca. down to J&H Marine in Stockton. I could not be happier with my experience with them! Lyle heard me out on my view of the problem and had me drop the boat and leave it. Mind you this is a 1979 Bayliner. A boat that has seen a lot of use. By the next day J&H had pressure tested my drive unit, identified the problems, and began correcting them after Lyle let me know the diagnosis and prognosis of the situation. When I picked up the boat and test drove it on the water a few days later it performed...flawlessly! No noise, smooth operation, power on demand. Like a new boat again. And...for a very fair and reasonable cost I might add. Lyle and J& H Marine took very good care of me and my baby and I will be happy to drive the 1-1/2 hours from where I live down to them anytime I need work done on this boat. Thank you so much Eric, Lyle and crew! read more

Great service. I had about 15 items on my list to review, inspect, install, quote, and Fred and I went over everything.

Excellent customer service. Very impressed with the shop's attention to detail. They found the issues with the boat and repaired them in a timely manner. I will be recommending J & H to my friends. read more

I have used J & H marine four different times and all my client rave over the outstanding service and excellence job done.

Yeh we are a fan. We had some stubborn issues on our SeaRay Sundancer 2005, and it took waaay longer to fix than we expected. So here is what makes these guys different; They hung in there, and would not release the boat until the issues were resolved. Follow up was good. They care about what they do, and value their reputation. read more
