I'm tired of pumping out the rainwater from my inflatable dinghy
everytime I want to use it to get to my sailboat mooring
. I thought I'd build an automatic bilge pump
and leave it in the dinghy
permanently. If the pump takes care of most of the rainwater, the sun will take care of the rest, drying out the dingy by the time I'm ready to use it.
I've already purchased a small Sahara automatic bilge pump
(500 gph, 1.2 amps). I've also found a site that sells small sealed AGM
batteries for jet skis. PWC (Personal Watercraft) Battery - sealed AGM batteries
. They have several manufacturers and batteries of every size starting with 4ah and going up. I thought I'd put both pump and battery
into a plastic box, drill a hole in the bottom side of the box so water
can get into the bilge
pump, and run a hose from the pump outlet to up and over the transom.
Does anyone see any problems with this setup, either as far as effectiveness or safety
? What size battery
do I need? Should I also get a very small solar
panel to put on the top of the box to charge the battery or is there a way I can charge the battery from my sailboat?
