I was trying to order a replacement O-ring and gasket for the Sherwood water pump on my M-18 engine from Torresen Marine and there was some confusion about the need for a gasket. They are checking it out and are going to call me back, but I thought I would ask here as well. On the drawing, part #2 is the O-ring and part #18 is the gasket. The gasket is between what looks like a backing plate and the pump body. My question to them was, "Is the gasket normally replaced when the impeller is replaced?"
So that is my question to you, plus, "How much of the pump has to be disassembled to replace the impeller? Do all the washers, retaining rings, bearings, etc. remain in place and only the impeller is removed from the shaft?" I've never done this before so I want to be sure I do it correctly.
