JLM MARINE Outboard Fuel Pump for Yamaha 115–300 HP (6E5-24410-10) — Aluminum, Corrosion-Resistant

JLM MARINE 6E5-24410-10 is a direct-replacement outboard fuel pump engineered to restore reliable fuel delivery on Yamaha 115–300 HP 2-stroke outboards.

If your Yamaha outboard stalls, hesitates under load, or has trouble starting, a failing fuel pump may be the cause. This JLM MARINE assembly is built to fit a broad range of Yamaha 2-stroke engines (115HP–300HP) and replaces multiple OEM part numbers, offering a corrosion-resistant aluminum construction designed for marine environments. The following details explain compatibility, performance features, and typical installation considerations so you can decide if this replacement suits your boat.

Which Yamaha models and old part numbers does this fuel pump replace?

This pump is made as a compatible replacement for Yamaha 2-stroke outboards across the 115–300 HP range. It covers many model years and specific part numbers to simplify sourcing.

• Fits Yamaha models: 115HP, 130HP, 140HP, 150HP, 175HP, 200HP, 225HP, 250HP, 300HP (2-stroke series).
• Replaces OEM codes: 6E5-24410-00, 6E5-24410-01, 6E5-24410-02, 6E5-24410-03, 6E5-24410-04, 6E5-24410-10.
• Also cross-references Sierra part 18-7349 for easier aftermarket sourcing.

How does the JLM MARINE pump stand up to saltwater and regular use?

The pump housing is machined from an aluminum alloy chosen for thermal conductivity and improved corrosion resistance compared with lower-grade metals. That construction helps the assembly handle marine conditions when maintained correctly.

• Aluminum alloy body dissipates heat to reduce thermal stress on internal parts.
• Surface treatments and precision machining limit corrosion in saltwater atmospheres.
• Designed to meet the mechanical fit and mounting locations of the referenced Yamaha units.

What symptoms indicate you should replace the fuel pump now?

Early detection prevents being stranded: look for loss of power, stalling at cruise, hard starts, or inconsistent throttle response. If those signs appear, testing and replacement of the pump is a practical next step.

• Engine stalls or flames out under load — common sign of fuel delivery loss.
• Difficult or intermittent starting after sitting — fuel pressure may be low.
• Irregular idling or power drop at wide-open throttle suggests restricted flow.

How straightforward is installation and what should a DIYer expect?

Installation typically follows OEM mounting points and hose connections, but confirm model-specific service manual steps before starting. Basic mechanical skills and standard marine tools are usually sufficient; professional installation recommended if you’re not comfortable with fuel-system work.

• Requires depressurizing fuel system and disconnecting battery before work.
• Follow torque specs and replace any worn clamps, gaskets, or hoses while accessible.
• Bench-check fuel flow and inspect for leaks before final engine start-up.

Who is this for: Boaters and marine technicians who own or service Yamaha 2-stroke outboards from 115HP to 300HP and need an OEM-compatible replacement fuel pump with durable aluminum construction. It’s suited for routine maintenance, repair after pump failure, or pre-season replacement to help maintain dependable fuel delivery. If you require exact-year compatibility, compare the part numbers listed above with your engine’s service documentation or contact a technician for verification.
