Glassed or bolted/screwed?

The pump(s) lift water out of the bilge to another location.
Sometimes to the cockpit, sometimes the deck, sometimes to
a thruhull on the side or stern.

No holes under water. Unless you are bringing seawater in
for some purpose. Underwater holes are always, or should
always have a manual shutoff, called a seacock. Which
makes them expensive.


You might get a copy of Don Casey's Inspecting the Aging
Sailboat, International Marine. Very basic.
More useful,more $$$, is Casey's This Old Boat, Turn a
rundown fiberglass boat into a first-class yacht on a
shoestring budget. Same publisher.
This may be your best bet at this juncture.



There are as many ways to install bilge pumps as there are
bilge pumps and skippers. My way is to install them on a
board you can lift out of the bilge for cleaning and maintenance.
Some will just have them on the end of a hose lowered
and clipped somehow into the bilge. Again, check out
what other Commander's have done, either in the Gallery
or Technical pages here on the pearsonariel.org website.
