[Public-List] deck mounted bilge pump

[R Kirk]

I was not concerned with pump capacity - gph.  Doesn't mean much if your bilge is pumped in two minutes or three. If the electric pump is not enough to keep up with the inflow, you're sinking and have other problems. My solution, since I swung at a mooring and so didn't have electric power, was to use a wave operated float pump similarto https://tinyurl.com/4cjvnp6f . It was 100% reliable.  Worked wonderfully in bumpy Annapolis harbor. Throw it over the side Sunday evening when you catch your mooring and return next Saturday to a dry bilge. Isobar didn't have any electric pump but the Whale always worked as advertised.

Me too…. I consider the electric pump a convenience, but being more reliable and more powerful, the manual Gusher 10 is the main pump.  The output ratings for electric pumps are measured at the spigot, with no head.  Even a few feet pushing up water reduces this theoretical output dramatically.
