Boat Overheating



Have a 115 Etec Evinrude. Used to overheat whenever going into plane, getting speed. Changed full water pump kit, both T stats. Issue went away with 3 or 4 people max in boat, occasionally overheated at speed with 4, rarely. Thought problem was solved, took 7 people out, overheated whenever getting onto the plane, 30 secs into getting speed. At a loss of why.

What is your model and serial number?

You may ask your tech about changing to a 19# pressure relief spring if your motor has the 22# spring installed.  It is a factory approved change

Re: Boat Overheating

So is what your saying is that the extra weight is not letting to boat pick up speed enough before overheating, so it's needs to open up the pressure relief at a softer pressure?

Re: Boat Overheating

Cannot say for sure but your whole cooling system should be inspected and if it still overheats with new parts, if needed, then change the spring.

Re: Boat Overheating

Anything to look for if I look at the pressure relief valve?
