Yamaha Outboard Marine Parts & Spares

Yamaha outboard parts: from 2.5 to 425 hp

At Repuestos Marinos we specialise in Yamaha outboard parts across the whole range, from the 2.5 hp portables to the big 425 hp V8s. More than 700 references in stock spread across 73 sub-categories, covering both the classic two-strokes and the current four-stroke line-up.

Yamaha is the most widespread outboard on the Spanish coast, which means there are engines from every era still out on the water. We work with genuine Yamaha parts and approved aftermarket alternatives, covering both current models and the eighties and nineties two-strokes that are still going strong.

Yamaha outboard parts diagrams and search by model

If you would rather locate the part on the drawing, we have the Yamaha Engine Breakdowns and the Yamaha Lower Drive Breakdowns, organised by figure and callout number just like the official catalogue.

We cover the F (four-stroke) ranges: F2.5, F4, F5, F6, F8, F9.9, F15, F20, F25, F30, F40, F50, F60, F70, F75, F80, F90, F100, F115, F130, F150, F175, F200, F225, F250, F300, F350 and F425; and the two-stroke series: 2A, 3A, 4A, 5C, 6C, 8C, 15F, 25B, 30H, 40X, 55B, 60F, 70B, 85A, 115C, 150A, 200A and 225D. The full model designation and the serial number are on the plate on the transom bracket: that is the information we need to confirm fitment.

Yamaha outboard servicing: kits and intervals

Water pump kit (impeller): inspect annually and replace every 2 years or 200 hours. This is the service that saves the most engines. A worn impeller will let the engine overheat at high revs even though the tell-tale is still spitting water.

Oil and filter (four-stroke): first change at 20 hours, then every 100 hours or once a year. On two-strokes, check the oil tank level and that the injection pump is working properly.

Spark plugs: every 100 hours or once a season. Yamaha specifies NGK and CHAMPION depending on the model; match the heat range given, not just the thread.

Anodes: inspect every season, replace once they have lost more than 50% of their volume. An outboard has anodes on the gearcase, on the transom bracket and sometimes under the cowling: check them all.

Gearcase oil: change annually. If it comes out milky, water is getting in and the seals need replacing before the gears are damaged.

Fuel filter and VST filter (on fuel-injected models): every 100 hours. A blocked VST filter causes misfires at high revs that are hard to diagnose.

Genuine and aftermarket: warranty and 24-48 h delivery

Genuine Yamaha parts come with the manufacturer's official warranty. Aftermarket parts meet OEM specification and are tested for marine use. Every product page clearly states which is which and lists the engine models it fits.

Delivery in 24-48 h to mainland Spain and the Balearics, 3-5 days to the Canary Islands and the rest of the EU. Orders placed before 14:00 ship the same day. Returns within 14 calendar days, plus technical advice by phone and WhatsApp for questions about fitment or parts diagrams.

Frequently asked questions about Yamaha outboard parts

Which Yamaha outboard models do you cover?

The entire range from 2.5 to 425 hp. Four-stroke: F2.5, F4, F5, F6, F8, F9.9, F15, F20, F25, F30, F40, F50, F60, F70, F75, F80, F90, F100, F115, F130, F150, F175, F200, F225, F250, F300, F350 and F425. Two-stroke: 2A, 3A, 4A, 5C, 6C, 8C, 15F, 25B, 30H, 40X, 55B, 60F, 70B, 85A, 115C, 150A, 200A and 225D.

Where do I find the model and serial number of my Yamaha?

On the plate on the transom bracket, on the side of the engine. We need the full model designation and the serial number to confirm fitment, because many parts change between versions of the same model depending on the year of manufacture.

How often should the impeller on a Yamaha outboard be changed?

Inspect annually and replace every 2 years or 200 hours, whichever comes first. It is the service that prevents the most serious breakdowns. Bear in mind that a worn impeller can let the engine overheat at high revs even though the tell-tale is still spitting water as normal.

Can I search for the part using the official Yamaha parts diagram?

Yes. We publish the Yamaha powerhead and gearcase parts diagrams organised by figure and callout number, just like the official catalogue. You can pinpoint the part on the drawing and go straight to the reference.

What servicing does a four-stroke Yamaha need?

First oil and filter change at 20 hours, then every 100 hours or once a year. Spark plugs every 100 hours or once a season. Gearcase oil annually. Fuel filter and VST filter every 100 hours on fuel-injected models. Water pump kit every 2 years or 200 hours. Anodes, inspected every season.

The gearcase oil comes out milky, what does that mean?

It means water is getting into the gearcase, usually through worn seals on the propeller shaft or the driveshaft. The seals need replacing as soon as possible: leave it, and the water will end up damaging the gears and bearings, turning it into a far more expensive repair.
