[Public-List] whale pump update

[Mike Lehman]

It is much easier to sevice the pump after removing the pump from the boat.
When I  did mine, i founf that the aluminum plate that holds one of the
rubber valves in place was badly corroded. While you can purchase a
replacement part, I used the old one as a template and made a new part
using a piece of fiber board of the same thickness. No more corrosion and
the rubber valve seals perfectly...the pump has never worked better
