The SHURflo Series float switches are reliable switches for your boat. They come in a complete line that includes a solid-state control, mechanical, standard float switch, and protected cage switch. The installation location for the pump should be at the deepest position in the bilge, away from high heat sources like engines, etc. The switch will activate the bilge pump when the water level reaches 1-3/4 (44mm) and will turn off the bilge pump when water level falls to 3/4 (19mm).

Product Usage Instructions

  1. Locate the pump at the deepest position in the bilge and mount it to the hull or pad with stainless steel screws.
  2. Use 16 AWG wire for wire leads. For installation over 20 feet, use 14 AWG wire. Wire is tinned to prevent corrosion.
  3. To reduce water wicking corrosion through wires, make all connections with waterproof connectors above all splashing bilge water.
  4. Keep all wire connections above the highest water level and seal the wires with a waterproof marine sealant to prevent corrosion.
  5. Install the Bilge switch cage for optimal performance.
  6. Always test pump and switch before operation.
  7. Do not pump oil, diesel fuel, gasoline or other flammable liquids overboard. This switch does not prevent the discharge of oil or chemicals into the water. Please take appropriate measures to prevent discharging oil and chemicals.

If replacing the SHURflo Piranha Bilge switch (359-101-00 or 359-111-00) with SHURflo Bilge switch (359-101-30 or 40), use the following procedure for installation. Please contact SHURflo customer service for any questions.

Installation

Location
Locate the pump at the deepest position in the bilge. Keep away from high heat sources; engine, etc. Mount to hull or pad with stainless steel screws.

Mounting
For best performance, switch should be mounted horizontally. The maximum mounting angle is 20° from vertical.

DO NOT DRIVE SCREWS THROUGH THE HULL
Operation
The switch will energize the bilge pump when water level reaches 1-3/4” (44mm) and will turn the bilge pump off when water level falls to 3/4” (19mm). SHURflo recommends installing the Bilge switch cage for optimal performance.

Electrical:
Wire Leads
Use 16 AWG wire. Installation over 20 feet, use 14 AWG wire. Wire is tinned to prevent corrosion. To reduce water wicking corrosion through wires, make all connections with waterproof connectors above all splashing bilge water.

Wiring tips

  • Twist wires together to reduce RFI (radio inter-ference)
  • Always use waterproof splices and connectors. Make connections above water line, if possible.
  • Use recommended fuse stated on bilge pump label.
  • Fuse MUST be between battery and panel switch. Some panel switches may have a fuse in them.
