6AH-24410-00 Mechanical Fuel Pump Assembly

Mechanical Fuel Pump — Compatible with select Yamaha F15C F20B F20G F25G Four-Stroke

Which pump is this?

This is one complete mechanical diaphragm fuel-pump assembly for small Yamaha four-stroke outboards in the 6AH-24410 family. Suffixes are not interchangeable by horsepower name: 6AH-24410-00-00 and -01-00 cover F15C / F20B rows (about 2007–2026 in the table); 6AH-24410-70-00 and -71-00 cover F20G / F25G rows (about 2017–2026). Compatible with those Yamaha four-stroke codes in the fitment table. It is not the older 66M-24410 pump (17FP004), not the 68T-24410 F6 / F8 / F9.9 family (17FP006), and not an electric pump. Some catalogs mention F9.9H / F13.5B — those codes are not in this SKU’s fitment table, so do not order on that name alone.

Signs yours is due

• F15 / F20 four-stroke cranks long when hot, then runs once the primer bulb is pumped — the small 6AH diaphragm has taken a set.
• Carburetor or vapor-separator bowl goes lean after a short sit; fuel smell at the 6AH-24410 body.
• You already replaced 66M-24410 on an older F15 and it still does not look like the pump on a 2007+ F15C — wrong generation.
• Not cooling: weak tell-tale is the water-pump impeller in the lower unit.

Will it fit?

Compatible with Yamaha F15C and F20B four-stroke codes on 6AH-24410-00 / -01, and F20G / F25G codes on 6AH-24410-70 / -71, years as listed (2007–2026 depending on suffix). Read the suffix on the pump you remove. Mapping from this SKU’s fitment table: F15C 2007–2021 = 6AH-24410-00; F15C and F20B 2022–2026 = 6AH-24410-01; F20G 2019–2021 and F25G 2017–2021 = 6AH-24410-70; F20G / F25G 2022–2026 = 6AH-24410-71. F20B and F20G share a 20 HP badge and use different suffixes. Horsepower alone does not prove fit. F9.9 / F13.5 names are not promised on this page.

Engine horsepower alone does not prove fit. Match the number stamped on the pump you remove to the OEM column.

Every row is from this SKU fitment workbook (11 rows after empty-line filter). Same horsepower name shipped different pumps.

OEM and swap numbers

OEM / predecessor numbers keep the engine-brand column. Aftermarket cross-refs are numbers only.

Wrong part

• NOT 66M-24410 — older F15 / T9.9 generation (17FP004).
• NOT 68T-24410 — F6 / F8 / F9.9 / T9.9 family (17FP006).
• NOT 67D-24410 (F4) and NOT 6C5 / 6CJ midrange four-stroke pumps (17FP002).
• NOT an inline fuel filter and not an electric / VST high-pressure pump.

What ships

One complete mechanical fuel-pump assembly. No hose, no strainer, no carburetor kit.

Often replaced together

Fuel strainer / filter on F15 / F20 kits is a different 26FFK SKU. Older 15 HP 66M pumps are 17FP004. F6 / F8 / F9.9 68T pumps are 17FP006.

Install

On these small four-strokes the pump sits on the block with a pulse passage in the gasket. Photograph the inlet / outlet / pulse before disconnecting. Match 6AH-24410-00 vs -70 to the stamp — do not assume F20B and F20G take the same suffix. Clean the pad, align the pulse hole, snug the screws evenly. Prime the bulb, leak-check, idle on muffs. If it still will not pick up, check the tank vent before you blame the new pump.

Frequently Asked Questions

Will this fit my Yamaha F20?

F20B rows use 6AH-24410-00 / -01. F20G rows use -70 / -71. Both 20 HP names are in the table under different suffixes. Read the stamp.

Will this fit F9.9 or F13.5?

Not from this fitment table. Some sales catalogs list those names; our Sheet 01 does not. Do not order this SKU for F9.9 / F13.5 on a badge alone.

Is this the same as 66M-24410?

No. 66M is the older 15 HP generation. 6AH is the later F15C / F20 family.

Electric pump?

No. Mechanical diaphragm, crankcase pulse.

What ships?

One pump assembly. No filter.
