" I've been really happy with John's work. He is professional, responsive, and easy to do business with, even remotely. He was able to cost-effectively diagnose and fix several problems with my 30 year old boat - it's running better than it has in years. Also very pleased with his winterization and shrink wrap services. "

" I had been having issues with my 260 hp 350CID engine overheating. I had two marine mechanics work on the issue to no avail - problem persisted for more than a full season. I was beyond Frustrated. I took the boat and the unsolvable problem to McPartlin Marine. Within a week I was informed by the mechanic that the raw water pump housing (which was newly replaced) was defective / warped and causing the issue. I was thrilled that someone was able to problem solve so effectively. Since this issue, I have had them replace my lower unit, adjust the carburetor and replace the fuel pump. The boat now makes weekly trips of more than 50 miles on lake Michigan with NO issues. McPartlin marine has also been priced very reasonably for the service they provided, they were more competitive than others I have worked with in the past. I am certainly able to give McPartlin marine six stars (or more). "
