These high capacity pumps are built to industrial standards. They are built for boats that are generally permanently moored, and are at least 30 foot long. Boats over 40 foot long often have 24V electrics so we stock a 24V version of the RULE 2000. Even if you get your boat serviced by professionals, it is still not a bad idea to carry a spare bilge pump. The 24V RULE 2000 is the most commonly used 24V bilge pump in Australia. All include a snap-on strainer base and mounting hardware is provided. Work with all float switches in RTM range.
