I hired Poseidon Marine to diagnose an engine with a rough power band and low RPM issue. Although the engine was eventually repaired, my overall experience was extremely disappointing. The first technician did not appear familiar with my engine and could not determine how to connect his diagnostic equipment. Before properly scanning it, he told me the spark plugs were definitely the problem and instructed me to spend approximately $200 on new plugs. They did not fix the issue. He then diagnosed a faulty injector, but because his equipment had not been properly connected, I questioned how that diagnosis could have been confirmed. Poseidon later sent Jeff Harth, who was exceptional. Jeff was knowledgeable, professional, and familiar with the correct diagnostic process. Unfortunately, he had to repeat much of the first technician’s work. Jeff later returned, installed and programmed the injector, and successfully repaired the engine. I have nothing but positive things to say about Jeff and his work. My main complaint is how the company handled the unnecessary expense from the first visit. Tracy from billing, who identified herself as a regional manager, called requesting payment. I explained that I disputed the first technician’s charges and wanted to speak with management before my card was processed. The call ended abruptly, and my card was charged despite my objection. I repeatedly tried to reach someone with the authority to review the situation but could not receive meaningful assistance. Tracy eventually offered to remove only a small service visit charge, which did not fairly address the amount billed for work that largely had to be repeated. Jeff deserves full credit for repairing the engine. However, good technical work does not excuse poor communication, questionable billing practices, or the lack of a fair process for resolving a legitimate concern. I will not use Poseidon Marine again and cannot recommend them. I strongly suggest researching their reviews and other customers’ experiences before hiring them. I sincerely wish I had done so beforehand.

RUN, do not walk away from this service. I contracted with Poseidon Marine to come onsite and take care of three services on my boat (radio/trim tab install/outboard service). In addition to a monthly membership fee that was charged / positioned as a credit card authorization for service, the technician that arrived had no idea what he was doing. With initial concerns about installing new trim tabs (he thought my Garmin GPS transducer on the back of the boat was a trim tab) and outboard maintenance, I asked him to just move forward on replacing my existing stereo unit with a new one already onsite. I stopped back by in 2 hours (at $225 / hr) to find that he had only taken off the motor cowl (?), removed several access panels on the boat and unscrewed 6 bolts on the center console dash removing the gauge panel and radio. Having concerns that it took 2 hours to unscrew 6 screws on a console, I asked for the service to be stopped at 4 hours total ($875 + the membership fee) knowing at that time the radio could possibly be installed, but not likely. 4 hours in and I have no radio installed, 6 screws that I paid $875 + to be removed and had to reattach and install the new radio myself (which ended up taking me 45 minutes to do). You are much better off taking your boat to a stereo business that charges $150/250 to swap out a stereo head unit and brick / mortar marine service company that can install trim tabs in 3 hours or so at $600/700. I will say that they took a lot of photos of the boat and materials that I supplied that were supposed to be installed. The report noted additional work that needed to be done that I could pay them $225 an hour for. Most of which, as a boat owner, you already know are there and need to ultimately be dealt.

Jetski took on water Friday evening I scheduled an appointment for Saturday Morning at 8am. They called me at 824 am and told me someone would be there soon Mechanic didnt show up until 1115am. When the mecanic got there he had no clue on how to fix a Jetski. He told me the Jetski Mechanic was not available until Monday and didnt feel comfortable trying to fix it. I told him that doesn't work because my Jetski needs to be fixed today because it took on water inside the engine. Had to dispute the charge. What a waste of time. The guys come to you unprepared and with little to no tools. 0 Stars

Our experience with Poseidon Marine was extremely disappointing. A technician came to assess our boat, but no repairs or parts were installed. We were later charged over $1,000 without the authorization we were told would be required beforehand and were billed for several hours that we dispute. We made numerous attempts over the course of a week to resolve the issue directly with the company. Unfortunately, communication was poor, promised callbacks never happened, and several customer service interactions were rude and ended abruptly. After disputing the charge with our credit card company, we were threatened with legal action and told they would place a lien on our boat. We were willing to pay for the technician’s actual assessment time, but we could not agree with the charges as billed. After this experience, we went back and read many other customer reviews describing concerns that were similar to ours. In our opinion, those reviews accurately reflected the experience we had. We cannot recommend this company and encourage others to do their research, carefully review billing policies, and read customer reviews before choosing their services.

Poseidon marine is charging me 19.97 every month. We have tried to contact them to stop this and they continue to charge us. I have charged fraud against them on our account.

Same experience as the rest of these posts I wish I would’ve checked the BBBS there’s nearly 80 complaints about these guys

June 26, 2026. I had agreed to getting my steering assessed, and a 100 hour service done on my Evinrude motor. I agreed to a small $200 assessment fee and gave my credit card information. The day the technician arrived, I watched him work on my steering and asked some questions about other services. I spent about an hour with the tech, just learning from him about marine services. I had earlier gone out and gotten parts and fluid for working on my steering, those weren't purchased by the company. I let the tech work for another half hour or so before I checked back with the tech. He needed a thermostat and I agreed to go drive and pick it up which would be 100x cheaper than the company ordering it and waiting for the part to arrive. I left my boat with the tech, when I arrived back just an hour later he was done, my motor was serviced except for the thermostat which I installed easily. Later that same afternoon, I got a charge for 1,522$ on my credit card. The invoice follow up from the company was very generic and gave no prices behind parts, how many hours of service were compiled on my motor, and why was my bill about $600 more than it should have been. The tech wasted time inspecting my trailer, my lights, my safety equipment things I DID NOT ASK FOR. The company had the nerve to say my boat was a full 8 hour day, when I know for a fact it was less than 2 hours. I tried for days to get in touch with the company but they just pretend that the person you need to speak with in billing is currently unavailable. Joke of a company.
