Removable Manual Bilge

Decided to add a manual bilge to my Sib for two reasons.

1 Bailing water accumulated by spray, breaking waves and rain when out in the boat on the water.

2 Pumping out wash water after the Sib has been washed out (the drain plug is around 25mm from the bottom of the sib so there's always a good few litres of water left in there after washing that don't come out the drain)

I wanted the pump to be mounted to the transom but didn't want to drill more holes in the transom.

I decided to use my existing fishing rod holders to attach the pump.
I widened the block to accomodate the pump.
The block is a piece of pressure treated wood wrapped in duct tape.
I've used this for my rod holders for 5 years with no need to paint or replace the tape.
A simple wipe with a soapy cloth cleans the salt off.

I use the factory fitted honwave eyebolt (permanently sikaflexed in the transom) to clamp the block to the transom. SEE BOLT IN THE PIC

The aluminium transom runner which holds the floor in serves to hold the block to the transom by preventing it rotating.
The eyebolt clamps it to the transom.

Had to modify the suction end of the pump to accept a smaller hose to fi through the space in the floor at the drain plug.
Pump works well and expels the water out over the transom.
Cheap and cheerful - the way I like it.

This forum really needs a "most holes drilled in a transom" competition!

Hi Jeff yep the the pump works like a champion with the tapered extension and small hose.
If anything it's suction has been concentrated / improved due to the smaller siphon.
I used epoxy to fit the tapered extension piece (old air bed pump adapter) into the end of the pump.
It was a snug fit and worked fine even before I used epoxy on it.
After thd epoxy set I built up sheets of glass matt and resin over the top to strengthen it further.
Works a treat.

cheers going to get one was looking yesterday but the gap i have is only 3/4 inch so a squashed hose will do fine just for the bit of water left in that the drain wont empty.
