I have a 1994 Beneteau Oceanis 351 and the numbers on the old prop cannot be read. The diesel engine is a Perkins. Would anybody know what propeller this boat would have come from the factory with? Also, I would appreciate any recommendations on the best place to purchase a new prop. With only a small shaft nut for sacrificial metal, I am afraid over the years my prop has become a bit of sacrificial metal itself. Thanks -
