Bilge 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.
