Re: 06 evinrude E-Tec 225 overheating?

Had the same problem where the engine would overheat and the alarm would sound but the engine didn’t slow down to slow mode. The temp would get to 180 degrees, just shy of the 190 degrees that would cause the engine to go into slow mode. The CAUSE was found to be pin holes in the copper tube going from the water pump to the power head. FIXED!

Re: 06 evinrude E-Tec 225 overheating?

Had the same problem on my 2007 etec 250. Engine overheat with a hot alarm but engine did not go into slow mode. Diagnosed where temp reached 180 which was enough to trigger the alarm but not hot enough to reach 190 which would trigger the slow mode. Cause found to be minute pin holes in the copper tube that connects the water pump to the power head. FIXED!

Did you or the tech find the pinhole problem by using a water pressure gauge, even a temporary hookup, and comparing the readings to the factory specs?

Re: 06 evinrude E-Tec 225 overheating 200 ho

I have been having the same problem.with a 2011 200HO.

i have to ask you few quetsionsif thats ok. Your engine temp at idle was good? at what RPM or speed did the temp rise to 180+? 

My engine Idles fine, but overheated and and did not shut engine to safe mode. (similar to yours) I replaced water pump, same results. last month i went about 30 miles with 4 guys and gear run fine, and then the overheat issue returned. this weekend went about five miles with only wife and limited load and the overheat light came back on. we ran @185-187 , then temperature returned to normal

etect2thetank: How did you go about the bypass w/ tee direct to the EMM? Can you provide photos? I'm having the same problem- EMM hot alarm without slow mode. 2006 225 Etec had 300 hr service w/ new water pump, poppet spring & large intake scoops installed late last season. Still getting hot alarm. Its getting REAL old.
