I replaced the engine block on one of my Crusader 270's and the engine is overheating so I'm looking for some advice. The block is new but the rest is from the original engine. The engine ran great for the first trip after the rebuild and overheated the second time out. Nothing appears to have changed.
I plan to look at the following things and would love any additional pointers
1) Thermostat
2) Radiator Cap
3) Raw whater Impeler (There is water coming out od the exhast port on the back of the boat, but I haven't compared the amount with the healthy engine yet)
4) Coolant levels. I put almost 4 galons of coolant in and there does not appear to be any leaks.
My temp gauge also decided to stop working. When I use the temp sensor from the other engine it reads below 200 yet coolant appears to boil.
