Hi There,
I'm just new to the forum as of today.
The original 8.7's were built with a manual hand operated
bilge pump which was installed in the port aft area of the
cockpit. An
electric pump and float was optional. In either case
bilge water is ejected
overboard. The factory used a "anti-siphon loop even though the through-hull was above the water line, this prevented water ingress while heeling.
