Browse marine engine parts and accessories for fuel systems, controls, outboard gear, anodes, propellers and maintenance projects.

Marine engine, fuel and propeller ranges

The engine, fuel and props range covers parts and accessories that support boat propulsion, fuel handling, controls, protection and servicing. Use it to navigate between engine accessories, fuel tanks and fittings, steering controls, propellers, outboard accessories, anodes and trim-related products. Each product area has a different role, so choose by the job being done rather than treating all engine parts as interchangeable. This helps narrow the choice between servicing, fuel handling, corrosion protection and propulsion hardware before comparing product details.

Common areas include engine accessories, fuel tanks and accessories, engine controls and steering and boat propellers.

Planning repairs, service and upgrades

Before buying, identify the engine type, model, fuel system, control setup and the part being replaced. Some accessories are service items, while others affect steering, corrosion protection or propulsion performance. Product fitment information and manufacturer instructions matter, especially where parts connect to fuel, steering or engine systems.

For maintenance and protection, also compare marine anodes, outboard accessories and oil extractor pumps.

Buying checks before ordering engine parts

Identify the engine make, model and year before searching for service items or replacement parts.
Confirm whether the part relates to fuel handling, controls, corrosion protection or propulsion before comparing products.
Check fitment details against the existing part or application guide rather than choosing by description alone.
Keep manufacturer service intervals and recommended oils in mind when buying maintenance items.
