A word of caution, I cracked a head on a 42' 216. the # 1. The temp gauge was not getting any water to it. For some reason the older 216's have this problem with flow if the water jacket is not flushed before starting up. A lot of folks didn't run anti freeze I suppose. You probably need to ask the folks here, the 235, 261's have larger jackets. Doc.
