I am filing this complaint against Poseidon Marine Mechanics regarding excessive charges and unsatisfactory service performed on October 12, 2026, on my 2022 Yamaha 255 FSH (Invoice #3746). I contacted Poseidon because one engine would not start. I was promised a technician around 3:30 PM, but he did not arrive until approximately 5:20 PM. By the time he diagnosed faulty spark plugs, nearby parts stores had closed. I offered to drive approximately 40 minutes to purchase the plugs myself to minimize costs. Poseidon informed me I would continue being charged $325 per hour while the technician waited, despite their late arrival contributing to the parts availability problem. The technician spent time conducting unrelated vessel inspections, checking safety equipment, taking photographs, and preparing documentation. Although the contract authorized a multi-point inspection, I question the reasonableness of these activities during an expensive emergency engine repair visit. The technician texted me the parts location at 6:41 PM after completing his assessment and departed before 7:00 PM. I was charged $928.44, plus $24.14 in credit-card fees, totaling $952.58. My engine was never repaired and remained inoperable. I acknowledge signing an estimate listing a $325 service-call fee and $325 hourly rate. My $500 deposit was credited toward the invoice. However, I dispute the overall reasonableness of nearly $1,000 in charges for this unsuccessful service visit. Additionally, Poseidon emailed me offering potential discounts for providing a FIVE-STAR Google review, raising concerns about its review solicitation practices. I request a full refund of $952.58, a detailed accounting of all labor charges, and an explanation of the company's service practices. I have retained the signed estimate, invoice, emails, inspection report, and technician's text message as supporting evidence.

We are currently in the process of dealing with Poseidon Marine, whatever you do do not do business with these people pay particular attention to all the reviews that are negative. Stay away from these people and this company and it’s many locations.

I called Poseidon and told them that my Simrad autopilot was wandering, and my steering was sloppy. I told them I thought there might be air in the hydraulic steering line. The tech came out and did trouble shoot. He found air in the line and the autopilot needed an update. He did not bring his purge equipment, nor did he bring his laptop for the upgrade, but I was charged over $800. The next week he returned with the equipment he should have brought the first time. He bled the line, uploaded the update which took two minutes, then we did a sea trial. It took a total of 2.75 hours. I was not only charged for a second trip charge, they charged my credit card over $900 for the second trip which should not have been necessary. So, a job that should have taken one trip and cost $800 ended up costing over $1,700. When I called to question the amount of hours being charged and the second trip charge, I was told that I had to pay for the tech to do his paperwork, and a manager would call me back. You guessed it. No one ever called me back. I will never use them again, and I'm warning others not to use them.

Buyer beware! I just got charged over $500 for the technician to drive around shopping for a gallon of coolant. Here's the transcript of the call I had before they sent out the technician. "I let some air into the system and so the impeller overheated, uh, and the coolant, some of the coolant overflowed so you know it needs to have a little bit of coolant" The technician showed up with the impeller, but no coolant. The tech had to spend 2 hours driving to multiple stores before he came back with it. So my 1-hour impeller replacement cost me over $1,300. Thank goodness it only took him two hours to find the coolant. The way they bill, they could leave to get a part and spend endless hours doing so. All the while billing at $225/hr.

I should have read their reviews before I hires them I needed my boat generator repaired. I already had the boat gone over by another mechanic that said i needed a starter motor for the generator but needed two people to do the job. I explained this to Poseidon and they said they would do the job. They sent one person in a truck with sprinkler service to my slip. I told them they needed two people for the job. He gave some vague excuse. At end of the day their billing department called me to get paid for 7 hours of work. This happened every day they went down there. They kept finding new things to bill me for. Went down after i thought the job was done. Generator wont start. Opened the hatch and the fuel line was disconnected. The generator case was left opened and rags left behind. I went to complain and got voice mail. Called my credit card to complain. Now they said they would send some mechanic and meet me at the boat. They never showed. Called and they said i had to pay their bill first before completing or at least evaluating the job. This is why they bill by the day and never seem to end. Beware

company mis diagnosed, overcharged for unnecessary parts, sent a technician that knew nothing about the system on my boat and then argues with you.

Requested a service tech to come out to trouble shoot my port engine wouldn't start. Met the tech on the dock as I was trying to connect my boat to shore power. The shore receptacle was 50A and my 2 shore plugs were 30A. He said, 'I never seen plugs or receptacle like that'. I immediately dismissed him. I was charged $165.16 for emergency service and $516.00 for 1 hour. He was there 10 minutes, and I have a witness of the whole event. DO NOT USE THIS COMPANY, THEY ARE SCAMMMERS.

Very dissapointed with this company! They advertise like they are a reputable company but for an hour and 15 minutes to check a couple batteries in my boat and in the Yamaha Waverunner cost me almost $800. The technician was on the phone with his supervisor for most of the time and maybe spent 30 minutes total and the rest of the time writing up a report. I am sure they did not pay him much of that - I would not be so dissapointed if it went to him. They take your credit card up front and charge it immediately for obvious reasons. I do not see many happy customers! Also - do not post John 3:16 on your website if you are ripping people off...
