Santo Cruz, 1980, 2667, Single 351W, V-Drive, once thru cooling. Would love to know the original set up of the cooling system. From thru hull intake location to engine driven sea water pump. When I purchased mine, the thru hull was located forward of the engine left of the V-Drive with no seacock? Impossible to get access. I moved the thru hull and added a seacock aft of the engine just inside the port engine stringer. Located the strainer low on the port fuel tank stringer. This does not work as the Sherwood G21 mounted engine pump only has about 0.5' of suction head. (Won't suck)
The engine pump sucks water thru the hull strainer, seacock, V-Drive cooler, and tranny cooler. The only things on the positive or discharge side of the pump are the exhaust manifolds, and engine jacket feed.
Obviously this isn't correct. Ideally all components to be cooled should be on the positive or discharge side of the pump. I'm about the fourth owner with as many re-powers. So, I'm sure this set up has been altered. Hard to believe Carver would have done this goofy setup from the factory.
Thinking of losing the engine driven pump and installing a Jabco (or similar) 12V pump with at least 2' of suction head capability just after the strainer. If anyone could help with pic's of similar models, or diagram of Carvers original set up that would be huge. Sanity check.
