Ok, it seems that the head isn't pumping in my "new" boat. It's an '89 H30 and I would think it's the original head. I know that there are service kits available, but as the head is original and in a semi-disgusting condition (visually) I figured I'd just buy a new one. Just how hard is this to do? It wouldn't seem too involved, but just want to make sure before I take the "plunge." Any words of wisdom for the soon to be plumber? Thanks.
