Hello everyone and thank you for any advice/tips in advance. Long story...
I have a 2012 Sea Doo 180 SP that has started having an issue with overheating. I have noticed that it will only shut down on temperature when I operate the boat wide open throttle after about five to ten minutes. The temperature alarm will not trigger if I operate the boat at 6000 rpm or lower. I took it into the local shop and they replaced the temperature sensor stating it was out of range. After getting the boat back we did a boat run of about 119 miles averaging about 25 MPH (heard this is the best for gas consumption) with no issues and with the temperature staying between 190-205. On our way back and almost to port, I decided to open up the throttle and again the boat overheated. I took it back to the local shop where they replaced the thermostat and performed a lake test where they ran it wide open and it overheated again. Now they are telling me that it is a bad head gasket that will need to be replaced and that since the boat has been overheating that the head will probably warp and need machining. I have never noticed or smelled any coolant leaking from the system, nor any loss of coolant from the reservoir. If it was a bad head gasket causing hot exhaust to leak in the cooling system, would it cause an overflow or a hose to burst from the excess pressure? Also, wouldn't this become an issue on the long boat run since with the system pressuring up over that length of time? Any help would be much appreciated before having to spend a ton of cash on a misdiagnoses.
