The boat is a 1978 century. The serial number tage are worn away so that the only number i can get is the gimbal housing number, which i have found out is used on several models. There is a partial number remaining on the transom plate inside the boat. It is a 350 chevy, and from what i can tell it could be an 888, 898, or early alpha 1. Im trying to figure what i have so i may order correct parts. Any help is greatly appreciated. And where is a good place to find some of the specialty tools needed to work on these.
