12 Volt Sump Pump
If you have a larger boat or yacht you know that one of the continual challenges you face is keeping the interior dry. Many larger boats are subject to leaking, and this water can collect at the bottom of your hull. It is always a good practice to install a 12-volt sump pump. With a sump pump continually operating, this excess water can be flushed out. The reason you want a sump pump that can be operated with a 12-volt power supply is that you can connect it up to a battery. That way, if the primary power source for your sump pump goes out, you will still be able to use the battery backup.
A good example of the kind of equipment that I’m talking about here would be the Jabsco 18660-0121. I found this item priced at just under $155. Manufactured by Jabsco, this 12 volt sump pump has a self-priming motor — and it is powerful enough to lift water up to 4 feet. This pump is able to move out your excess water at a zippy 380 gallons per hour.
