Take the starter to the local decent autoparts store and have them test it.
Chevy starters used to short out the armature and suck lots of current and
turn very slow. You can take a broken hacksaw blade and clean the armature
slots to fix the problem at times.

I agree with checking the connections...mainly the grounds.
The vast majority of oddball electrical problems are ground related.

I had problems starting my starboard engine the other day. Port engine
started fine. I had a full charge on all batteries and even used the
emergency switch to pull from all batteries to try and start the
starboard engine. Still no luck. It turns over very slowly but not
enough to start. Sounds like a low battery but they are fully charged.
Maybe the starter either bad or not connected properly? Any ideas?

thanks!!!
