I just bought a used 1990 sprint 266 bass boat with a 1990 Mercury 115 hp outboard motor (2-stroke).
A couple times when I have turned the key to the accessory position (where the electrical system is engaged but before the engine turns over), I get a high-pitched, sustained tone. Is this a warning tone? There are no warning lights on the instrument panel, so I am a little lost/concerned.
The noise can start when I first turn the key or when I begin to start the engine after drifting on the lake for a while. The engine seems to be running fine and the noise generally stops after a few minutes of driving.
Any ideas?
