I recently became owner of another boat. A 19 ft Glas-Ply hard top, 1971. It seems to be a very solid boat. But, I am thinking of new power for her. She has an OMC 155 outdrive, with a 6cyl buick motor. She runs good, but I am thinking of a Out board conversion with a 175-200 hp, or a mercruiser 4.3 with an Alpha series. Has anyone had a conversion on their I/O? And are you happy with it. Also, would appreciate suggestions on who to take it to? It sure would open up the fishing room. Thanks in advance. By the way, the current power plant and outdrive might be for sale???
