SouthMarine Fuel Pump Assembly for Yamaha 25–90HP Outboards 6A0-24410-00 Direct-Fit OEM Replacement

This replacement fuel pump assy is built to match the fitment and routing of the original Yamaha part numbers (692-24410-00, 663-24410-00, 6A0-24410-01 through -05) so you can restore fuel delivery without modifying hoses or mounts. It supports a wide range of Yamaha outboard models and horsepower bands (25–90 HP) used on small boats, inflatables, and tenders. The unit is suited for two-stroke outboard engines and is designed for easy installation using the OEM mounting points and connectors.

How do I confirm this pump fits my Yamaha outboard?

Verify compatibility by checking the Yamaha part number on your existing pump or consulting your engine’s parts manual. This SouthMarine assembly covers the common OEM numbers listed and fits most 25HP–90HP two-stroke Yamaha engines produced roughly between 1995 and 2015.

• Compare your current part number to 692-24410-00 / 6A0-24410-00 series.
• Check engine horsepower: 25, 30, 40, 55, 60, 70, 75, 85, 90 HP.
• Applicable to many Yamaha series (C, TLR, MLH, TJRZ, TLH variants).
• Designed for outboard, two-stroke engine configurations.

What should I expect during installation?

Installation typically follows the same steps as the OEM pump: remove the old unit, transfer any brackets or clips if required, and connect fuel lines and wiring harness. No special tooling is needed beyond basic hand tools, and the pump is manufactured to align with factory mounting points to simplify the swap.

• Disconnect battery and relieve fuel pressure before beginning.
• Remove existing pump and retain any mounting hardware if necessary.
• Fit new pump to OEM mounting points and reconnect fuel lines and electrical connector.
• Prime system and check for leaks before running the engine.

What performance and durability features does this replacement pump offer?

The SouthMarine fuel pump assembly is produced to match OEM flow and pressure characteristics so it restores predictable fuel delivery and engine response. Components and seals are selected to resist ethanol-blended fuels commonly used today, improving service life when installed and maintained correctly.

• Engineered to replicate OEM flow and pressure behavior.
• Seals and diaphragms compatible with modern marine fuels.
• Corrosion-resistant materials for marine environments.
• Quality-tested to ensure consistent operation after installation.

How can I maintain the pump to prevent future fuel issues?

Routine inspection of fuel lines, clamps, and the pump body will catch wear before it becomes a failure. Replacing fuel filters and keeping the fuel fresh and stabilized also reduces contamination and stress on the pump assembly.

• Inspect hoses and clamps for cracks or soft spots annually.
• Replace in-line fuel filters at recommended service intervals.
• Use stabilized, clean fuel and minimize ethanol long-term storage exposure.
• Check for fuel leaks after initial installation and during seasonal startups.

Who is this for: Boaters, mechanics, and DIYers who need a reliable, direct-replacement fuel pump for mid‑1990s to 2015 Yamaha two-stroke outboards in the 25HP–90HP range. It is ideal for owners restoring older engines, maintaining fleet outboards, or replacing a failing OEM pump with a cost-effective aftermarket assembly that fits factory mounts and connections.
