1996 evinrude-hot signal on low rpms

[smsean]

I have an omc boat with the warning system built in.What I am getting is a hot signal on low (1000-1500)rpms.Could it be that one of the temperature switches is bad? With more rpms or throttle the signal goes out.any help would be appreciated!thanks<br />[*]null<br />

You may actually be HOT! An impeller that has taken a "set" or is worn will work OK at higher rpm's and lose effeciency at low speeds.<br /><br />If you've never done it, it's time for impeller service!<br /><br />If you run in salt water, thermostats can stick also. Raising the boat speed unseats the pressure relief and some cooling water goes through.<br /><br />Both are relatively easy to check and/or replace.

thanks for the response! I put thermostats in it 2 years ago. And an impeller in it last year.went through a lot of weeds this year. I'll put another impeller in it and we'll see how she goes!
