Volvo Penta Water Pump

[twaterski]

I have a 1995 Volvo Penta SX drive with a 3.0 GS on a 175 Glastron. I am familiar with impeller water pumps in the outdrive of outboard engines. I know that a good rule of thumb is to replace these when in doubt of...previous owner...previous use...or after a few years of use.

The schematics for the Volvo Penta SX show a raw water pump feeding a circulation water pump. Both pumps are mounted to the engine. I don't see an impeller type water pump in the outdrive on the schematics. Here are the links to the schematics I have.

My question: Is there an impeller water pump between the upper and lower unit of a Volvo Penta SX? Is there a water pump in the Volvo Penta SX that needs to be maintained?

Re: Volvo Penta Water Pump

The impeller pump is called a raw water pump and is NOT in the Volvo SX drive, nor any other Volvo drive for that matter. They are always engine driven.

So there is no water pump between the upper and lower unit in the Volvo Penta SX outdrive?

While you are at it, head here and find your OEM service manual for your engine and drive. It's free. I once bought the Seloc manual too before I knew any better...you will be much better off with the OEM manual.
