1-1/8 Boat Bilge Pump Hose Kit - 1100 gph Automatic Pump

In this review of the 1-1/8 Boat Bilge Pump Hose Kit the bottom line is simple: it is a compact, practical kit for small boat owners who need a reliable automatic discharge kit without a lot of extra plumbing work. The kit centers on a 1100 gph 12V automatic bilge pump with a built-in reed sensor, paired with a 6 ft 1-1/8 in kink-free PVC hose, an ABS 1-1/8 in thru-hull fitting and two 304 stainless steel hose clamps; the single biggest reason to buy is the ease of installation and a complete matched outlet system that avoids cutting corners when routing bilge discharge above the waterline.

Key Features

• 1100 gph automatic pump: Provides strong 1100 gallons per hour flow for rapid bilge clearing without a separate float switch thanks to the built-in electronic reed sensor.
• 1-1/8 in outlet match: The kit is designed for pumps with a 1-1/8 in external outlet, ensuring a snug connection and fewer adapters when installing the discharge line.
• 6 ft kink-free PVC hose: The flexible hose contains iron wire and a corrugated spiral anti-kink structure that preserves flow and resists deformation when routed.
• Durable fittings and clamps: The ABS thru-hull connector resists breaking and seals well while the 304 stainless steel clamps resist rust and hold the hose securely.
• Cuff-less smooth hose end: The inner hose is smooth and cuff-less to reduce leak points at the connection and offer a stable, low-friction flow path.

Who It's For

This kit is aimed at owners of small powerboats, sailboats, inflatables with onboard pumps, RV owners using a 12V pump, and anyone who needs a compact discharge package sized to a 1-1/8 in pump outlet. It suits DIYers who want a ready set of components to route a bilge pump discharge above the waterline without sourcing mismatched parts.

Those who should look elsewhere include owners who require below-waterline thru-hull installations or pumps with outlets other than 1-1/8 in; the product is explicitly not intended for below-waterline thru-hull connections and will not fit pumps with a larger or smaller outlet without additional adapters.

Pros & Cons

Pros

• Complete matched kit speeds installation by including pump, hose, thru-hull fitting and clamps.
• Automatic 12V pump with built-in reed sensor removes the need for a separate float switch.
• Quality materials-PVC hose with iron wire, ABS connector and 304 stainless clamps-improve durability in marine environments.

Cons

• Not suitable for below-waterline thru-hull use, so it is limited to above-waterline discharge setups.

It is a sensible buy for small-boat owners who want a ready-to-install solution that avoids adapter headaches.
