Detroit 8.2 litre Jabsco Pump

[Jeff Isenhour]

I have a 1987 34 Mainship mark III with 8.2 litre Detroit power. Need to replace the Jabsco raw water pump but cant tell if it is a 777-9001 or a 777-9003. It is pulley driven. How do I tell what should be on the engine. Pump housing looks like it may be original but is not marked at all as to model..?

Pretty sure the pumps on my DD8.2's are 777-9001; had to pull face plate to check; someone had turned it around. DD part # is 8924483. Have 2 of the little beasts in my Californian 34.

Thanks for the reply. This is my first trawler. Found out it is the 9001. Thanks again.
