[Public-List] deck mounted bilge pump

Thanks for the alternate view. Right now I think I probably do not
have the whale pump as it is not yellow in color. It has been
suggested that it may be a Henderson.

 A dissenting opinion: I find the Whale manual bilge pump incredibly
 unreliable.
 The slightest pinhole in the diaphragm or lack of seal in the flaps
and
 you can't get enough
 head to pull water up out of the bilge. The aluminium body very is
prone
 to corrosion
 if there is a scratch in the coating. And for some reason they use
 British Whitworth threads which make sourcing replacements difficult,
 expensive or both. It's capacity in terms of GPH is much lower then
the
 larger electric pumps. The ergonomics of pumping are poor; pumping
 more than a few minutes with get very tiring, very quickly.

 Manual bilge pumps are not required by Transport Canada on vessels
over 9m.

 I have 3 pumps on board. The Whale, a 2200gph Johnson and a 150gph
Rule,
 with the last on an automatic switch. Every spring, I dump the water
 tank into
 the bilge and exercise all 3 pumps. There are problems with Whale
almost
 every year, whereas the Johnson and Rule have failed only once each
in
 15+ years.

 "Oh" you say "but the electric pumps won't work if the batteries are
 underwater."
 I assure you, from experience, they will work just fine. The Johnson
had
 the bilge
 dry in less than a minute.

 I have, as I say 3 pumps. But the Whale is not the one I'm counting
on.
