Took my 2005 Basstracker out for the first time this year. Started the motor, a 40 HP outboard, at home before leaving for the lake. No problems.
Got to the lake and turned the ignition key on and a high pitched sound emanated from under the dash. Started the engine and had the same sound continue. As long as the key was in the on position the sound continued.
Any idea what this may be - and how to correct it ?
