He worked on my Parker and did a very good job. His worked ranged from adding new trim tabs to major engine repair. He did great work. Most recently I had him do work on my 60 HP Yamaha. Again he did good work. He convinced me that I had corrosion on the lower unit and it needed to be replaced. He even send me digital photos of the problem area. I was convinced this was a problem waiting to happen. James put on a new lower unit and added new gauges. I was pleased with the outcome.

Our boat was in need of significant repair and after several boaters and businesses in Dana Point Marina referred us to OCO we knew we were in good hands. We received frequent video updates and a valuable lesson in basic boat maintenance. It's tough to find mechanics you can trust, look no further for all of your boat repair needs.

When I got the boat back I had smoke from the engine bay on my first trip out 1/4 mile from harbor. Luckily sea tow and no major damage. It shifted smooth when I dropped it off, didn't shift after getting it back. Dangerous and incompetent to say the least.. ef these guys.. So i purchased an old but new to me 25' Flybridge with a 7.4L MPI mercruiser.. 30 year owner, very well cared for.. the engine shook when I bought it.. seemed like engine mounts.. I took it to Orange County outboards since they're a mercruiser shop in my area.. what a mistake.. after they rebuilt my stern drive they said just live with the shake... they said the guy I bought it from was lying.. it wasn't a reman'd engine cause it didn't have the tag (mercruiser stopped putting tags on remans) my first time having the boat back it almost burned down SERIOUSLY. Smoke from engine bay 1/4 quarter mile outside the harbor... I had to get sea towed back in.. I immediately let them know, they said they'd send techs out (their shop was full all of a sudden) and that was the last I heard of them.. Absolute garbage.. they took 4 months for 20 hours of billed work.. the work they did do was sound.. but for some reason they wouldn't fix the engine.. So next I took it to another shop, they fixed the engine mounts and the shake is gone.. amazing right!? the reputable shop also found the water pump had failed (mysteriously?) and also the shift cables that worked fine when I dropped it off were stuck when I got it back.. the new shop replaced the cables and it shifted smooth as butter again.. AVOID THIS SHOP IF YOU DONT HAVE A 35' dual engine cabin cruiser.. The mechanic at oc outboards seemed full of himself.. they also said I need to change the oil every 20 hours.. what a joke.. this is my 2nd boat, and I spend about 100 hours a year on the water and this will be my 6th season fishing socal.. I am very disappointed with them and I am considering seeking legal reparations because they almost burned my boat down do to negligence and caused damage.. We'll see.

Do not waste you money or put your boat in danger going here My opinion only based on my bad experience

I had an overheat problem with my Mercruiser 454. After installing new exhaust manifolds,…read moreElbows/risers, thermostat, then circulation and sea water pumps the problem still existed. We were at our wits end and getting discouraged as this was a new engine with less than 100 hours on it. As my wife works in the industry at a business with a similar name, we reached out to see if they could figure out what was causing our issue. Derek was very helpful and courteous as well as thorough with the inspection process. After a couple of days he figured out that water flow was being restricted at the transom due to a clogged inlet that was described simply as "mush". We obtained a new transom and had it installed. Derek called us up and said there was no more steam, the temp was back to normal and the motor was running fine. After picking up the boat, we took it to Elsinore for a test run with no issues. What a relief. For the scope of work performed, the cost was reasonable. That being said, everyone knows what BOAT means! Lol. A big thank you to Derek and the entire staff at Advanced Marine Service! Now we are bound for the river!
