I have a marinised Shibaura S753 [Perkins 104-10, Perkins Perama M30, Volvo MD2030, Caterpillar 3003, ford 1220 and there are lots more places this engine has been used]. It is a solid little engine that has found its way into lots of equipment, machinery and tractors, so parts are no problem at reasonable prices or full rebuild kits for that matter.
It has unknown hours or history. It does start easy if glow plugs are heated from cold or if warm no issue at all, no smoke under load either. But I would just prefer the piece of mind of a semi blank slate on the history of a boat engine.
I am more than capable of removing and installing an engine either existing or new. I would not rebuild one myself, that is beyond my skill level.
So what are some pros and cons? What have been your experiences? Suggestions? Recommended mechanics?
I am really struggling to make up my mind.
