Marine Engine Belts, Hoses, Fuel Lines, Coolant Hoses & Clamps
Shop replacement belts, hoses, clamps, and related engine-service parts for marine cooling systems, fuel systems, raw-water plumbing, exhaust hose runs, accessory drives, alternators, and routine maintenance.
Fitment Check
Ask Parts Desk
Match belt profile, length, pulley style, hose inside diameter, hose rating, clamp size, engine model, and fluid type before ordering.
Belts, hoses, and clamps are small parts with big consequences. Confirm dimensions, material, pressure or temperature rating, and the system being serviced before installation.

Fitment
Measure First, Then Match the Rating
Belts should match the correct profile, length, width, and pulley system. Hoses should match inside diameter, wall construction, bend radius, temperature rating, pressure rating, and the fluid they carry. Clamps should match hose diameter and service load.
Why It Matters
Heat, Salt, Vibration, and Pressure Wear Parts Down
Cracked belts, soft hoses, swollen fuel line, rusty clamps, loose connections, and chafed hose runs can lead to overheating, leaks, fuel odors, loss of charging, and avoidable downtime.
Search by engine brand, part number, belt number, hose size, hose type, clamp size, or the system being serviced.
Belts
Drive belts, V-belts, serpentine belts, alternator belts, raw-water pump belts, and accessory belts for engine service.
Hoses
Fuel hose, coolant hose, raw-water hose, wet exhaust hose, water hose, heater hose, and replacement hose runs.
Clamps
Stainless worm-gear clamps, T-bolt clamps, constant-tension clamps, and clamp hardware for secure hose connections.
Service
Inspect the Whole Run, Not Just the Failed Part
A belt, hose, or clamp failure can point to worn pulleys, poor alignment, heat damage, corrosion, chafe, age, pressure, vibration, or the wrong replacement material. Check the whole system while access is open.
Check belts under loadLook for cracking, glazing, squeal, dust, frayed edges, poor tension, or pulley misalignment.
Inspect hose conditionReplace hoses that are soft, swollen, cracked, oil-soaked, chafed, kinked, or heat-damaged.
Use the right clampChoose clamp material and style for the hose size, pressure, heat, and location in the engine compartment.
Carry sparesCommon belts, clamps, and short hose sections are useful onboard spares for trips and seasonal service.
FAQ
Belts, Hoses & Clamps Questions
How do I find the right replacement belt?
Use the engine model, existing belt number, belt profile, width, length, and pulley setup. If the old belt is badly worn or stretched, verify the correct part by engine information.
Can automotive hose be used on a boat?
Marine systems often need hose rated for fuel, exhaust, coolant, raw water, heat, pressure, and engine-compartment conditions. Use hose approved for the specific marine application.
When should hose clamps be replaced?
Replace clamps that are rusted, distorted, stripped, loose, over-tightened, or no longer holding evenly. Critical hose connections should be inspected regularly.
What should I check before ordering fuel hose?
Confirm inside diameter, fuel type, required rating, hose route, bend radius, fitting size, clamp style, and whether the hose is used for supply, return, vent, or fill service.
