Re: Runnin hot...bah!
Tin Man, your first post said the temp gauge was showing 145-150, make sure you're chasing an overheating problem and not a grounded out sensor wire. Disconnect the over heat temp switch wire( tan/blue stripe)at the sensor, run the boat and see what happens. The alarm wokrs off of a ground circut, anywhere in the harness, if the wire becomes grounded, it will set the alarm. If the poppet valve is removed, the block will not fill with water completely and create steem pockits. I wouldn't even bother with pulling the powerhead or lower unit till I confirmed the problem is high temp, and not a wireing problem.
