I was wondering why my fishfinder is not shutting down when the Alternator is putting out 17.5V, it's just a cheap $120.00 Lowrance lcd unit ?

Alot of marine electrronics can run on both 12 or 24V as some boats run 24V systems in them.

My mechanic took out the brand new CDI voltage reg. he put in when he rebuilt the motor and put back the original OMC one and it has been working fine, (15V max ), he told me the CDI's are crap and he isn't using them anymore.

I got news for your mechanic, CDI makes them for BRP now. It's just the luck of the draw wether you get a good one or not. Even OEM parts fail out of the box.
