Trident Bilge & Bait Box Hose — Part #1201186

A 50-foot roll of corrugated white polyethylene bilge hose designed for above-the-waterline bilge drainage and bait box applications. The corrugated construction allows the hose to flex and route around obstacles without kinking, while molded-in cuffs every 12 inches make cutting and connecting straightforward at any point along the length.

What This Product Does

Bilge hose routes water from the bilge pump outlet to the discharge point above the waterline. The corrugated polyethylene construction resists oily bilge water, mild acids, and seawater without degrading, and the flexible profile allows it to navigate tight routing paths in the hull without kinking. The molded cuffs every 12 inches mean you can cut the hose at any cuff and get a clean, consistent end for barb or clamp connections.

Installation Tips

Cut the hose at a molded cuff for a clean, consistent end. Use stainless steel hose clamps at all connections and ensure the discharge end terminates above the waterline. Route the hose with gradual bends rather than sharp angles to maintain flow. Secure the hose at regular intervals to prevent sagging or chafing against hull components.

Technical FAQ

Q: Can this hose be used below the waterline?
A: No — this hose is not rated for below-the-waterline use. For through-hull or below-waterline applications, use a hose specifically rated for that purpose.

Q: Can I use this for my livewell supply line?
A: This hose is not recommended for pressurized livewell supply connections. It is suitable for livewell overflow or drain lines on the unpressurized side.

Q: What size bilge pump outlet does this fit?
A: This hose has a 1-1/8" inside diameter. Confirm your bilge pump outlet barb size before ordering — common bilge pump outlets are 3/4", 1-1/8", and 1-1/2".

Parts Desk Insights

Best use case: This is the standard choice for bilge pump discharge hose on most recreational boats — the 50-foot roll gives enough length for most single-boat installations with material left over for future repairs or a second run. The 1-1/8" diameter matches the outlet on many common bilge pumps in the 500–1500 GPH range.

Common issues we see: Customers occasionally order without confirming their bilge pump outlet diameter, then find the hose doesn’t fit the barb. Always check the pump outlet size before ordering. We also see installations where the hose is routed below the waterline — this hose is not rated for that use and should be replaced with an appropriate below-waterline hose if that’s the application.
