I just thought it would be more convenient to have a shore power plug installed on the boat rather then running the cord over the gunnel. Maybe not. I'm still a little concerned about galvanic corrosion primarily with my prop, and shaft so I'd like to find out if anybody has had any issues with this in freshwater, especially when slipped in a marina? I have an in-board engine with single screw, and there's no sacrificial anodes on the boat like an IO, or outboard. Maybe I'm worrying too much, but I don't have to tell you guys how expensive it it to maintain a boat so I want to cover all the bases. I've never slipped a boat before this year.
