Last year I was out on the lake and had my boat over heat, after talking to a few friends and listening to there knowledge it was determined that the impeller and water pump had failed. So I pulled apart the lower unit and sure enough there was a big blob of what was my impeller. So I promptly changed it, sadly never taking it out the rest of the year.
Fast forward to a few weeks ago when I decided I was going to get my boat out. I proceeded to do the dewinterizing and start up and dumb me forgot to put the muffs on. End result toasting the impeller and pick up tube. I ordered the parts and replaced everything again only this time hooking the muffs up for the start up. After 15 minutes the temperature started creeping up past 160 by the time I turned it off I was at 200.
So my question is this, did I put the impeller in backwards? Is it the t stat? Or what I’m fearing is it the exhaust manifold? How can I determine what is going on for sure so I can stop wasting time and money? Is there a source where I can find diagrams or manuals?
