The bilge pump and fuse circuit feeds directly from the power distribution post/buss. The main power feeds via the red
wire to the accessible fuse holder outside (located on the back of the boat top), then through the green/brown wire to the
pump.
The bilge pump is a 24VDC sealed, brushless, automatically-activated unit. The self-contained, solid-state electronics
energize the pump motor on a pulse method; if the amp draw is above a preset threshold, it indicates that water is present
and the pump will continue operation until the amp draw drops, indicating that no water is present. Note: If the inlet is
suffi ciently blocked, no water will enter the inlet and the pump will not sense amp draw, so it will shut off , even though
water continues to accumulate in the hull. It is imperative that the daily inspection includes removing the vent plate and,
using a fl ashlight, inspecting to see if water is building up in the hull.
A bilge pump fuse, which is accessible for service from the outside of the hull near the vent plate, is located in the power
feed line from the main buss.
The replaceable fuse is a 3-amp time-delay/slow-blow cartridge-style fuse.
Note:
Using any fuse type other than this specifi cation could result in poor performance and/or pump failure.
