Hi everyone. We purchased a 2004 Hunter 33 recently. Here is the story so far. Picked up the boat in Toronto (Pickering) and everything seemed fine. We motored most of the way to Halifax which is about 1400 miles or so. The motor ran great. Side note I had installed a Flexofold 3 blade prop before leaving. Running the engine around 22 to 2400rpm which gave us 6.5kts. No problem until approx 150 hrs later I get high temp alarm.
I check through hull all seems good. Check water strainer, good. Check impeller, looks good but replace anyway. All hoses seemed fine. Start engine and water is coming out of exhaust, but exhaust sounds a bit throaty if you know what I mean.
Ran lower rpm for the rest of way to Halifax and no problem. Then it started again!
Weird how it’s fine for a long period then gets hot for no apparent reason.
I have heard that it could be the heat exchanger or something to do with coolant.
Anyone have this kind of problem?
