A few notes for those of us with the Westerbeke 42B.
Raw Water Pump.
First, there is a new raw water pump, P/N 48080, which is a bit larger but directly replaces the old one, P/N 033636. From our Sailnet discussion group, here’s an email from one captain who went through the exchange: “The seals started to leak on my seawater pump so ordered a new one. Found out Westerbeke had replaced it with larger model. The frame and bolt holes match but the pump is larger, has a higher volume, and the impellers are not interchangeable. Just finished mounting the new one. Keep the 45-degree elbow on the inlet. The new pump comes with the 90 degree fitting on the outlet but not the 45. Everything fit and it works fine. Having the old one rebuilt for a spare. Don’t forget
