    '87 Johnson GT 150 alarm

    My alarm sounds steady when I first start up, but goes away after idling for 5 minutes or so. Any ideas? Other than a new rig, that is.

    It has been almost a year. The pee stream is strong.

    I'm considering removing the thermostats to see if that's the problem.

    Maybe some kind of restriction somewhere in the system.Your impeller should be fine then.

    Thanks, I hadn't thought of that. Any idea how I'd check that?
