JLM MARINE Outboard Fuel Pump for Yamaha 115–300 HP (Pair) — Aluminum Alloy Direct-Fit Replacement

JLM MARINE 6E5-24410-00 is a pair of aluminum outboard fuel pumps designed to replace Yamaha 2-stroke 115–300 HP models and restore reliable fuel delivery. Whether you're a professional mechanic or a weekend boater, having a direct-fit replacement fuel pump on hand prevents extended downtime and keeps your vessel running smoothly. These two pumps match multiple Yamaha OEM part numbers and Sierra cross-references, fitting common 2-stroke outboard engines from 115 through 300 horsepower. Built from corrosion-resistant aluminum alloy, they balance strength and heat dissipation for repeated marine use.

Which Yamaha engines will these pumps fit?

These pumps are engineered to fit Yamaha 2-stroke outboard engines across a broad horsepower range, covering many popular mid- to high-power models. They replace several OEM part numbers and offer a straightforward swap for compatible models when the original pump shows wear.

• Compatible horsepower: 115, 130, 140, 150, 175, 200, 225, 250, 300 HP
• Replaces Yamaha numbers: 6E5-24410-00, -01, -02, -03, -04, -10
• Sierra cross-reference: 18-7349
• Fits typical 2-stroke outboard fuel pump mounting patterns

How does construction affect pump durability and performance?

The assembly is machined from an aluminum alloy chosen for corrosion resistance and thermal conductivity, helping the pump shed heat and resist saltwater environments. Those material properties improve longevity while maintaining dimensional stability for a secure fit and consistent fuel flow.

• Aluminum alloy body for rust resistance in marine settings
• Good thermal conductivity to reduce localized overheating
• Precision machining for proper sealing and flow rates
• Supplied as a matched pair for spares or dual replacements

What symptoms indicate a fuel pump replacement is needed?

Common signs that a fuel pump is failing include intermittent stalling, hard starting, or sudden power loss under load; these symptoms often point to inconsistent fuel delivery. If you notice those behaviors, replacing the pump promptly can prevent being stranded and restore predictable engine response.

• Intermittent engine stalling or flameouts while underway
• Difficulty starting after cranking the engine
• Loss of power or hesitation under throttle
• Visible fuel leaks or damaged pump housing

How easy is installation and what should I prepare?

Installation is direct for compatible Yamaha 2-stroke models—mounting holes and connections match OEM geometry for a straightforward swap. Basic mechanical skills and common hand tools are sufficient; always follow manufacturer torque specs and inspect fuel lines and fittings during the service.

• Direct-fit replacement; no major modifications expected
• Requires basic tools: wrenches, screwdrivers, and thread sealant if specified
• Inspect and replace fuel hoses, clamps, and filters during installation
• Install both units if you want an immediate spare for future reliability

Who is this for Boaters and marine technicians who maintain Yamaha 2-stroke outboards from 115 to 300 HP will benefit most from this set. It's ideal for owners who prefer keeping a ready spare on board, fleet operators minimizing downtime, and repair shops replacing worn pumps with an affordable, corrosion-resistant aluminum assembly. The twin-pack provides convenience and value for routine maintenance or emergency replacements.
