HI KTP. As a PSC31 owner I was very interested in your project.
Kind of off topic but if you have a stern lazzeret (sp?) it should have spring loaded pins allowing it to be readily removed. Granted, to get in there requires a pretty small frame. Just mentioned as I didn't figure this out for the first four years of ownership!~} Happy Holidays
Are you still thinking about a diesel/solar electric trawler. I am building one using a Navy surplus 50' utility boat. I have removed the Detroit 671 and am installing a 60 hp 900 rpm 3 phase 208 motor direct drive. I am also installing a diesel gen and a VFD to control the motor. Contact me if you have any questions or recommendations.
