Finally on April 10, 2026, a mechanic came to our home to make the repairs: replacing the wear rings on both jet pumps. Typical maintenance. The mechanic sent to our home did not have the basic tools (like a vice or wrench) or to make the repair. Instead he said it could only be repaired back "at the shop." He took possession of both jet pump assemblies and some other related parts to go back to a workspace where they could be repaired. Later that day, April 10, we were informed by Poseidon that the repaired parts would be returned to us on June 9, 2026. YES, you read that correctly -- 60 days to finish the job. Since April 11, 2026, we have made more than three dozen phone calls, requesting the return of our property or an address where we could pick up our parts. Our calls have gone unanswered and our requests have been ignored. We speak with a receptionist who assures us we will get a return call but we have never received a return response. The parts they took include two jet pump assemblies and related components with a replacement value exceeding $1,800 each. Yep, you read that correctly, Poseidon has in essence "stolen" our parts totally almost $4,000. That's how they treat a paying customer. Not only are we missing two jet pump assembly we were charged and paid in full for repairs. During this same period, our credit card was charged multiple times under various merchant names associated with the business, including BoatRx Poseidon Marine, Poseidon Marine, and Poseidon Plus. This is what we've paid Poseidon to date: * March 24, 2026 - $19.97 * April 13, 2026 - $714.32 * April 13, 2026 - $495.47 * April 23, 2026 - $19.97 * May 26, 2026 - $19.97 These charges were paid in full for services not rendered on parts that were "stolen" from us. After weeks of unsuccessful attempts to communicate and recover our property, we were left with no choice but to send a formal certified CIVIL THEFT demand letter, dispute the charges with our credit card company, and pursue additional legal remedies. Every business can make mistakes. What matters is how they respond. In our experience, the most troubling issue was not the repair work itself--it was the complete lack of communication, failure to return calls, failure to provide updates, and failure to return property after repeated requests. Not only did we call the main phone number we attempted to reach the owners, Jeremy Davis and William Hunter Harris, by email and mail. If you are considering using this company, I strongly recommend you reconsider. Things happen but if you cannot count on basic customer service when issues arise you're putting yourself at great risk. Their communicated repair and return date of June 9, 2026 has now come and gone with no communication, no return calls, and failure to return our property. We took our skis to KM Cycle of Ft Walton and paid to have new pumps installed. Total repair bill, $5,000. Our hope is the law firm we've hired will have more success getting a response and potential customers understand the risks involved. This review reflects our personal experience as customers and is based on documented communications, invoices, charges, and requests for the return of our property.

To put it succinctly, this small company is a class above: hard working, no-nonsense,completely professional and as knowledgeable and experienced as anyone in the business. On top of this, their attention to detail and determination to ensure that the engine was in perfect working order when they finished was clear throughout the process. Add to this a very reasonable bill and one could not ask for more --especially here in the Florida market. I highly recommend them.
