I was recently given a 17 foot center console boat with a 1972 evinrude 100 h.p. electric shift. The outboard has had a new pump, thermastats, and all gaskets and seals replaced. The problem I'm having is that it will always run hot and sound the overheat alarm. The only time it runs for more than 5 minutes without the alarm sounding is when I use the flush kit. I was wondering if anyone may have any idea about what to check/replace to try to cure this problem. I'm new to boating and outboard repair so any help would be great!<br /><br />One other thing...I guess that the two holes on the back of the outboard (about 12" above the prop) are water outlets. If they are... I never have seen any water coming out of them no matter if I use the flush adapter or not. I have a Raytek laser temp gauge and in the lake the engine get to about 200 degrees in less than 5 min. When hooked up to a flush kit it never gets over 115. Someone help me please!
