" I have an old 2HP Yamaha P45
" I have an old 2HP Yamaha P45. Starts and runs just fine. But if I open up the throttle too far water STOPS coming from the exhaust, and the engine overheats. If I then set it at tickover for ten seconds there is a small cloud of steam, water starts coming out exhaust again, and everything is fine once more. I have replaced the impellor (twice).Checked everything I can think of(not much to check). I bought it secondhand. No manual. Am I missing something? Is the engine missing something? Previous owner was a tinkerer but no mechanic. "
