Cooling system pump---1980--2QM15

[Clarke Rudd]

My cooling system pump for the 2QM15 is leaking I have been unable to find the model of the pump or if it is made by Yanmar. Is it capable of being rebuilt...should I replace it? I took it apart but just greased it and reassembled it...there is a gasket that seems in need of replacement but again, I have very littlt nomenclature for this pump it does have 9F??-112 I cant read it all and it does not have a manufacture name. Help?

Jabsco?

Hi Clarke,Over on the "Cherubini" menu I recently posted this:"Is that the belt-driven pump mounted below the alternator? I think mine is the same and last year I overheated when the impeller seized. I had replaced the impeller in the interal pump and didn't even know about an external pump. Now I carry a couple of spares.How do you know the gpm rating? If its on the pump I can check this week. My maintenance manual has a page for a Jabsco 2760-0001 but I don't know if that is what I have. That page shows: 2.6 gpm @ 1160 rpm, 3.9 @ 1750, and 4.6 @ 2100. I just know that I see plenty of water coming out the exhaust and the motor runs cool, too cool. I bought a new thermostat but haven't installed it yet."This is probably what you have and Torresen has the parts(www.torresen.com).
