Re: Ran w/o Water(?)
Is this a boat with an Apha system....that has an added on engine driven pump so it can have full closed cooling? I had heard that for an Apha to have full closed cooling (adding the manifolds) the drive mounted pump does not flow enough water to remove the heat needed for full closed cooling, so some will add an engine driven pump...supposedly the impeller is left in the drive to cool the part of the drive that the exhaust runs through....not sure if any of this is right but I do recall hearing about an engine mounted pump having to be added for full closed cooling.
BTW changed the one in my Cobra after 2 years in salt water, looked good enough to leave in...kept it in its housing as a spare.
The one on the top of the pic is the old one.
