take a long look at how the thermostat is installed in your housing, its easy to put it in wrong, just find the right parts break down and it should show all the parts in their correct order

I have no tstat in it right now. I am going to put one in. Something I did not know but the boat tstat is different from a car, not the same.

Boat T-STATS are a lower temp, and are all stainless whereas most cheap auto stats are regular steel. A steel t-stat in a marine environment will NOT last long, and WILL make a mess of things. And don't forget the check balls in the T-stat housing. It may be worth your time and money to just buy a whole new housing with check balls and springs off EBAY.

I had the boat out for the afternoon today. It ran great, I had it full pin for about 10 min and the temp never went above 160. So the water impeller was the fix. So..

WOT is 30 mph and my rpm is 4 grand. So I think that means the prop is right.....

I have another prop I can try....

The boat has 15.5X17 and I have a spare 14.5X17. I was going to try the 14.5X17
