Engine Getting Hot

[jschildm]

Interesting ... I will definately keep that in mind. On another note, I see you are in the Joliet area. A buddy of mine is going to be moving up there around the end of September, so I might be up there for a visit sometime. Maybe I'll look you up if it happens to be boating season. What engine do you have?

Parts are out for delivery now. Planning on putting those in and everything back together, and then take her for a test drive this weekend. I am hoping the 160 degree t-stat isn't an issue, since it would start at 220+ while malfunctioning. I will update with results and more questions, depending on the outcome. Thanks again for everyone's input.

Got the new t-stat and hose in yesterday. Took it out today and all was fine .... until I started to get on it some. The temp gauge did the same thing it did the other times. I decided I was going to replace the impeller since I had one, and it was the last easy solution.

Sure enough, it worked like a charm after that. I got on it pretty hard with no issues. It started raining so we didn't get to run it that long, but I am pretty confident it was the solution.

I suppose this is a perfect example of why I should have put the spare impeller that I already had in the boat in there the first night it started acting up. Live and learn I suppose. I at least now have a spare t-stat and fixed the hose that was just waiting to get a hole in it.

Thanks again for everyone's insight on this issue! Next weekend will be the big test because I plan on 4 long days of boating, weather pending at least.
