6E5-24410-00 Mechanical Fuel Pump Pair (2)

Mechanical Fuel Pump Pair — Compatible with select Yamaha 115–300 HP 2-Stroke V4 / V6

Which pump is this?

This listing is a pair: two complete Yamaha 6E5-24410 mechanical diaphragm fuel-pump assemblies. Many 115–250 HP 2-stroke V4 / V6 motors run two of these pumps (port and starboard, or upper and lower on the block). OEM stamps include 6E5-24410-00-00 with the same-family suffixes -01 / -02 / -03 / -04 / -10 and superseding -09. Compatible with the Yamaha 2-stroke V4 / V6 rows in the table. If your parts diagram shows one pump only, do not buy this pair — use the single-pump page (17FP012). This is not an electric VST pump and not a 26FFK pump-plus-filter kit.

Signs yours is due

• V6 150–225 2-stroke goes lean on one bank at cruise while the other bank still smells rich — one of the two diaphragms has torn; this pair replaces both while the cowl is off.
• Fuel in the cowling around a 6E5-24410 body, or one pulse hose hard and cracked and the other still soft.
• Hard hot restart on a big 2-stroke that still has spark and compression on both banks.
• Not EFI four-stroke VST failure (F150 / F200 electric pump). Not a cooling impeller in the lower unit.

Will it fit?

Compatible with the same Yamaha 2-stroke V4 / V6 codes as the single 6E5-24410 family (examples: 115B, 130, 150, 175, 200, 225-class and later V6 rows in the table). Factory catalogs often skip serial fields. Suffix -00 vs -10 vs -03 is the same pump family. This page still ships two assemblies. Horsepower name alone does not prove you need two — read the parts diagram.

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 (126 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 a one-pump order. If you only need a single 6E5-24410, that is 17FP012, not this pair.
• NOT 692-24410 / 6A0-24410 — 25–90 HP 2-stroke family (17FP008).
• NOT electric / VST pumps 6E5-13907 / 63P-13907, and NOT Tohatsu 3C7-04000-1.
• NOT 26FFK047–051 kits (pump plus extra filter / hose parts).

What ships

Two complete mechanical fuel-pump assemblies. No hose, no filter, no extra gasket kit unless it is on the pump bodies in the photos.

Often replaced together

The single-pump page for this family is 17FP012. Pulse hoses and fuel filters on 115–250 HP 2-stroke kits are separate 26FFK SKUs. Electric VST pumps are a different product line.

Install

On V4 / V6 2-stroke Yamaha motors label port and starboard (or upper and lower) before you pull either pump. The pulse passages sit in the gaskets. Photograph both hose layouts. Replace both original-age pumps together if you bought this pair — mixing a 20-year-old mate with a new pump is how the second side fails a month later. Clean both pads, align both pulse holes, and snug the flange screws evenly. Prime, leak-check both bodies, then a muffs run. Do not install these diaphragm pumps on an EFI four-stroke VST system.

Frequently Asked Questions

Do I get one pump or two?

Two complete 6E5-24410 assemblies. If the diagram shows one pump, buy 17FP012 instead.

Will this fit my Yamaha 150 / 200 / 225 2-stroke?

Those HP names appear throughout the table. Compatible with the listed 2-stroke V4 / V6 codes only — and only if that motor uses two of these pumps. Four-stroke F150 electric pumps are not this part.

Is 18-7349 the same family?

18-7349 is a cross-ref number for 6E5-24410. We list the number only. This page is still a pair.

Can I install only one from the box?

You can, but this SKU is sold as a pair for motors that run two. Keep the second pump labeled if you only change one side.

What ships?

Two mechanical pump assemblies. No filter kit.
