Just recently purchased (acquired) an 87 Sea Ray with one blown engine and a tired second engine. It has the 4 cylinder merc motors in there. I already own an 86 26 foot single screw sea ray with a 350 and am very familiar with that engine.
What is the process to convert the 270 over to twin 350 small blocks? I do not know what ratio outdrives are on the boat but I'd imagine they are different that a v8 boat. I would go to fresh water cooling on both motors- is anything from the freshwater cooled 4 cylinders reusable? Do I have to add stringers? Is it worth while to convert or are the 4 cylinders not as bad as everyone says they are. I am extremely mechanically inclined and have no problem either rebuilding the 4 cylinders(if parts are available) or converting to 350's. Any insight or tips from past conversions(or attempts) would be appreciated. This new-to-me boat is cosmetically leaps and bounds above my 26 foot so I'd love to canibalize the 26 for 1/2 the parts to convert. Thanks
