Compact, automatic submersible bilge pump — model 03603 — designed for reliable marine bilge water removal with an integrated float switch for automatic on/off operation. This unit is offered as SKU 020-972 and sold under brand: Other.

Key Features

• Automatic built-in float switch: fully automatic activation when water level rises, no separate float required.
• 24V DC operation, suitable for most marine battery systems and offshore vessels.
• High flow performance: rated around 110–116 L/min (approx. 6,600–6,960 L/h) — effective for small to mid-sized boats and recreational craft.
• Oil-resistant, robust thermoplastic housing with stainless steel shaft for corrosion resistance in bilge environments.
• 1" hose connection (side exit), compact footprint and lightweight for easy mounting and service access.

Specifications and construction details align with common 03603-series submersible bilge pumps (oil-resistant design, plastic impeller housing, stainless shaft and 1" discharge). These build features deliver dependable performance for routine bilge clearing and intermittent duty marine use.

Typical Applications

Ideal for boats, small yachts, workboats and inland craft that require an automatic bilge pump with float control. Use as primary bilge management on vessels up to medium size or as a dependable backup pump to protect against accidental flooding.

Installation & Maintenance Notes

Mount the pump in the lowest point of the bilge on a flat surface, connect to a protected 24V circuit with appropriate fuse/cutout, and route the 1" discharge hose clear of bends or restrictions. Periodically clean the snap-in strainer/base to prevent clogging and inspect wiring and seals for corrosion.
