[Public-List] whale pump

[Mike Lehman]

Same on Gilleleje #505...I did this job yesterday.  To change the valves
inside it was necessary to remove the pump from the boat. Years ago, when I
rebuilt pump,
I noticed that plate to mount the exit valve, was badly corroded by salt
water and did not seal well so I used the original part as a pattern and
made  a new part from fiber board of the same thickness. (Thank you Whale
for making parts that fail so people will buy replacement pumps).

Also the backing plate under the deck was plywood which rotted...so I made
a new piece from PVC.

Bottom line, you have to remove the pump. George is right, two hands,  one
above deck with a screwdriver to hold the bolt from turning while removing
the nut under the deck.

Hope this helps.
