Recently bought a new (to me) 2010 Lowe Skorpion. First boat I have owned in a good 30 years and being retired need to try and do some things on my own to save a buck or two. I am not that mechanically inclined but willing to try.

My issue is that last time out after loading up and pulling off the ramp to staging area I could hear a whining buzzing noise, turns out the starter is happily spinning away and hot as heck. Pulled positive cable from battery to end that.

The key was in off position and this was still happening. Is my issue the solenoid or the ignition switch....possibly both? And I am worried if the starter having run for good 10 minutes at the ramp and probably that long coming of the lake might be needing replaced? Starter still works but maybe degraded the brushes?
