Hey Guys,
I've got a 1987 Glasstream bass boat with a 90 HP Johnson on the back. Recently, after I've cranked up the boat and start to edge the throttle forward just a bit (little bit faster than idle speed) the throttle box will produce a fairly loud alarm sound within 3-4 minutes of the engine running. If I turn the engine off, it stops, and then if I turn the engine back on, it makes the same alarm sound within another 3-4 minutes of running. The alarm is not constant, but its intermittent and will continue buzzing in 2-3 second intervals. It also seems to get worse the further down you are on the throttle.
I have a video of it as well if there's a way to upload.
Any thoughts?
