Re: 1996 Evinrude 225 Overheating
A '96 Evinrude 225 should have the System Check warning guage with the 4 LED's that will show what kind of problem you are having.<br /><br />Like the venerable Hadley says, use a temp gun to find out what temp your engine is actually running at on each cylinder head. Your dash mounted temp gauge only reads one head, not the other, plus they are not known for accuracy.<br /><br />There are 2 different water pump kits for that motor depending on the shaft length. If mixed up, they can cause a 25" shaft motor to overheat at high speed. There is also a "blow off" valve on the back of your engine that should be inspectd. Then there are 2 thermostats located on the top of the cylinder heads that require periodic changing.
