Raw Water Pump replacement
Raw water pump on Westerbeke showing has a leak and price being quoted for replacement Sherman pump is $832. Ouch. Any insight from others on replacing this part much appreciated.

Re: Raw Water Pump replacement
Fred, you can also just replace the pump seals. Provided the shaft isn't scored, new lip seals should fix and water leakage problem. Here's a pretty good writeup on bearing replacement on a Johnson pump which is similar to the Sherwood. https://marinehowto.com/rebuilding-a-raw-water-pump/
The option that Bill chose is also a very good one. The Orberdorfer pump has the advantage of a forward facing face plate so access to the impeller is much easier since you can actually see what you are doing rather than working blind.

Re: Raw Water Pump replacement
Thanks Gents. Good info to consider. Can't quite understand the Sherwood design with access tucked behind the pump.
