Electic Bilge Pump Installation
I have a 1984 C&C 35-3. It currently has two maunal diaphram bilge pumps. One in the cockpit and one under the port settee. I have several questions regarding upgrading this system. First of all, will this require a new thru hull? Can an electic pump be installed through the same thru hull as the manual and preserve function of the manual one as a back-up? The main pump now runs from the keel sump through corrugated hose and probably 4' static head. From everything I've read this corrugated hose should difinitely be replaced with a smooth one. The previous (and only) owner seem to do fine with this set-up during 28 years on a mooring and raced at least 10 Chicago-Mac races with it - so I believe it's up to the task of my coastal crusing requirements, but I would prefer the ease and piece of mind of an electric pump. As I will also be on a mooring and am assuming this will draw between 6 and 8 amps so I'm also concerned about coming back to dead batteries after an extended period away from the boat. Thoughts and recommendations about how others have handled this??
