Mercury Mariner Marine Parts & Spares

Mercury and Mariner outboard parts: 2.5 to 350 HP full catalogue

At Repuestos Marinos we specialise in Mercury and Mariner spares for the whole outboard range, from the portable 2.5 and 3.3 HP units to the large V6 and V8 FourStroke engines, the Verado series and the classic OptiMax and 2-stroke models. We carry over 2,000 Mercury/Mariner references, with genuine Quicksilver parts and quality-matched compatible alternatives, real stock and 24-48h shipping to Spain and the EU.

Mercury Marine covers both 2-stroke engines (classic, Seapro, OptiMax DFI) and 4-stroke engines (FourStroke, EFI and supercharged Verado). As Mercury and Mariner share the same parts breakdown, one reference usually fits both brands; that is why identifying the part by serial number or by the model breakdown before buying is key.

Mercury / Mariner parts by model

If you know your model and cannot find the part by family, look it up by the engine breakdown. We cover 2-stroke and 4-stroke from 4 HP to 300 HP: classic 6-9.8, 25-30, 40-50 and 65-90 HP series, the modern FourStroke EFI 25-60 HP, the V6/V8 65-225 HP and the Verado 135-300 HP series. The fastest-moving stock is the FourStroke 40-60 HP, the 25 HP and the 2-stroke V6.

Mercury Marine maintenance: service kits

We cover the full scheduled services in the Mercury manual: oil and filter change (4-stroke engines), water pump impeller inspection and replacement, spark plugs, anodes, thermostat, belts and lower-unit seals. Mercury recommends the first service at 20 hours or 30 days and then every 100 hours or once a year. The water pump impeller should be inspected every season and replaced every 300 hours or 3 years (sooner if the engine runs in silty water). In salt water, check the anodes every season and replace them if they have lost more than 30-50% of their volume.

Genuine and compatible: warranty and 24-48h shipping

All genuine Mercury / Quicksilver parts carry the manufacturer's official warranty. Compatible parts meet OEM specifications and are tested for marine use (brass, stainless steel, salt-resistant seals). 24-48h tracked shipping, 14-day returns and technical support by phone and WhatsApp for parts-breakdown or fitment questions.

Frequently asked questions about Mercury / Mariner parts

Which Mercury and Mariner models do you cover?

The whole outboard range, 2-stroke and 4-stroke, from the portable 2.5-3.3 HP units to the V6/V8 FourStroke and Verado up to 300 HP. As Mercury and Mariner share the same breakdown, most references fit both brands.

Are the parts genuine or compatible?

We stock both. Each product page clearly states whether the reference is a genuine Mercury / Quicksilver part or a compatible one. Compatible parts meet the technical specifications of the original and are approved for marine use.

How do I identify the right part for my Mercury?

Three ways: by OEM breakdown number, by engine model and power (e.g. 40 HP FourStroke EFI) or by asking our technical team by phone or WhatsApp with the engine serial number.

How long does shipping take?

24-48 hours to mainland Spain and the Balearic Islands. 3-5 days to the Canary Islands and the rest of the EU. Orders placed before 14:00 go out the same day.

How often should I change my Mercury impeller?

Mercury recommends inspecting the impeller every season and replacing it every 300 hours or 3 years, whichever comes first. In silty or muddy water, halve that interval.

Can I return a part if it is not the right one?

Yes, within 14 calendar days of delivery, in perfect condition and unfitted. We issue a refund or exchange for the correct reference.
