My 1987 Pacific built O 911s has 2 floorboard sections that lift out. I use
a bridgenorth bailer (bridgenorthbailer.com) and it takes out almost every
drop without having to stoop over. Awesome! I have an Attwood Sahara 750 gph
pump (3/4 inch) installed below the sole - fits perfectly. It empties into
the cockpit drain pvc tubing with a one way valve inline to eliminate back
flow. Took about 15 feet of plastic piping and although there is about a 5 foot
rise it works great when I flush the bilge and as an automatic backup in case
of a minor flood. (Use a Rule automatic/manual switch - the Atwood pump has
the float built-in). I also have a powerful hand pump with one way valve.
I also installed a "packless" bearing on the propshaft. Use loctite on the
retaining allyn screws or it may work itself loose! Drip free after 3 years
of use.
