Vetted UK outboard engineers

Outboard engine servicing near you

Annual services, impellers, winterisation and fault-finding — priced up front

Outboards fail for boring, predictable reasons: an impeller left one season too long, a gearbox quietly taking on water, or fuel that has sat over winter. An annual service catches all three, and it is the single cheapest thing you can do to keep a tender, RIB or dayboat reliable.

Post the make, model and horsepower with your berth or storage location and up to three vetted engineers will quote privately. Every professional on Marine Match is document-checked by our team before they can quote, and payment is only released once you confirm the work is done.

What an outboard service includes

A typical annual service on a four-stroke outboard. Two-strokes skip the engine oil change but everything else still applies — ask each quote to state exactly which of these are covered.

  • Engine oil and filter change (four-stroke) or gearbox oil check
  • Water pump impeller inspection or replacement
  • Spark plug inspection and replacement as needed
  • Fuel filter, fuel line and primer bulb check
  • Anode inspection and replacement
  • Gearbox oil drain, inspection for water ingress, and refill
  • Propeller, shaft and split-pin check
  • Cooling telltale flow test and run-up check

When to book

Annually or every 100 hours, whichever comes first. In the UK the best time is at the end of the season so the engine is not laid up full of salt water and old oil — and because spring diaries fill first.

What drives the price

Horsepower, two- versus four-stroke, whether the impeller is being replaced or only inspected, and travel to your berth. Quotes on Marine Match are itemised so you can see labour, parts and travel separately.

Symptoms worth booking now

Weak or missing telltale flow
Usually a worn impeller or blocked cooling passage — stop running the engine until it is checked.
Hard starting or stalling at idle
Commonly stale fuel, a blocked carburettor jet or a failing fuel pump.
Milky gearbox oil
Water is getting past the seals; leave it and the gearbox can fail.
Loss of top-end power
Often a fouled plug, restricted fuel filter or a damaged prop.
Excess vibration
Check the prop for damage and the engine mounts before running hard again.

Outboard servicing — FAQ

How often should an outboard be serviced?
Most manufacturers specify annually or every 100 hours, whichever comes first. Boats in salt water, hire use or heavy season use are normally serviced at the end of the season so they are not laid up with salt and old oil inside.
What does an outboard service cost in the UK?
It depends on horsepower, two-stroke versus four-stroke, and whether the engineer travels to the boat. Small portable outboards are at the lower end; large four-strokes with multiple filters and gearbox work at the upper end. Because Marine Match quotes are itemised, you can see labour, parts and travel separately rather than a single headline figure.
Can the engine be serviced without taking the boat out of the water?
Yes, for most annual servicing. Engineers work afloat at the berth or on the trailer. Only leg removal, gearbox rebuilds and some impeller housing work usually need the engine off the transom or a workshop visit.
Do I need a main dealer for a warranty engine?
If your engine is inside its manufacturer warranty, servicing normally has to follow the manufacturer's schedule and be recorded. Say so when you post the job and engineers can confirm whether they can service it without affecting the warranty.
Should I winterise as well as service?
On a UK boat, yes. Winterisation adds fuel stabilisation or draining, fogging or corrosion protection, water draining and correct storage position. Many owners book the service and winterisation together at the end of the season to save a second visit.
