Took our boat there hoping he could fix it. We originally were told it was a busted impeller so we bought a new one and a new thermostat got it back and got on the water it was worse. We were then told our 4 stroke fuel injected boat motor could run without a thermostat due to the water temperatures we have around here and that we basically didn't need one.... Wrong!!!! maybe with a 2 stroke you could get a way with that but not with a fuel injected 4 stroke like we have. We ended up paying over a thousand dollars for him to basically deep clean our engine and leave without a thermostat and the boat still wasn't fixed. If you don't mind going to someone who doesn't know the importance of a thermostat In certain motors then he's your man, but if you have a newer motor you may want to look elsewhere. read more
