Compatibility and Fitment
This assembly is built to suit Yamaha and Mariner outboards (all years noted by suppliers) and Mercury outboards from approximately 1989 to 1998 that use the corresponding connectors. Because models and fittings vary, check your engine and tank connectors before installation. The RWB Fuel Line Assembly Yamaha/Mercury 2.1m offers a practical plug-in replacement where 10mm hose and primer bulb assemblies are specified.
Compliance and Safety
Use only marine-rated fuel hose and secure all joints with the supplied clamps. After installation, prime, then inspect for leaks while the engine is running. Replace hose assemblies that show abrasion, hardening, or swelling. Dispose of fuel-contaminated components responsibly.
Marine Applications
Ideal for portable tank setups and repowers on runabouts, tinnies, and trailer boats using Yamaha, Mariner, or compatible Mercury outboards. The 2.1m reach suits common tank-to-engine distances while keeping bends gentle for good flow.
