View Black Heat ShrinkBilge and Livewell Hose Installation Tips
- Match hose ID to the pump, thru-hull or plumbing fitting.
- Use the correct clamp size for the hose.
- Avoid sharp bends that can restrict flow.
- Keep discharge runs as short and direct as practical.
- Support long hose runs to reduce sagging.
- Route hose where stored gear cannot crush or kink it.
- Inspect hose and fitting connections for leaks after installation.
- Protect electrical splices from moisture.
Why Hose Diameter Matters
The hose inside diameter should match the pump discharge or plumbing fitting. Installing a hose that is too small can restrict flow, while oversized hose may not seal correctly on the fitting.
For a bilge pump, using the correct discharge hose helps the system move water as efficiently as the installation allows.

Pro Marine offers the heavy-duty bilge and livewell hose in both black and white. Choose the color that best fits the boat's layout and installation preference.
Both colors are available in 3/4", 1" and 1-1/8" inside diameters.
