Shop Outboard Parts Impellers 100-Hour Kits
Fitment Check

Use your outboard brand, model, horsepower, year, serial number, shaft length, and current part number before ordering service parts.

Ask Parts Desk

Outboard parts can vary by engine family, model year, serial range, lower unit, fuel type, and factory replacement history.

Find Outboard Parts Faster

Search by Brand, Horsepower, Serial Number, Part Number, or Service Job

Outboard service parts are highly specific. Search by exact part number when possible, or combine the engine brand with the item you need, such as Mercury impeller, Yamaha fuel filter, Honda thermostat, or Suzuki anode.

Cooling & Water Pump Service

Keep Cooling Water Moving

Impellers, water pump kits, thermostats, gaskets, housings, and tell-tale fittings are common outboard service items. If service history is unknown, inspect the pump and cooling parts before the season.

Water Pump Parts Thermostat Gaskets Tell-Tale Parts

Fuel, Oil & Ignition

Service the Parts That Keep the Engine Starting Cleanly

Fuel filters, oil filters, spark plugs, plug wires, fuel pumps, primer bulbs, and related service parts help protect starting, idle quality, fuel economy, and engine life.

Primer Bulbs Plug Wires Fuel Lines
01

Match Horsepower and Serial Range

Many outboard parts change across the same horsepower family. Serial number and model year matter.

02

Confirm Two-Stroke or Four-Stroke

Filters, plugs, fuel parts, oil service items, and service intervals can be different between two-stroke and four-stroke engines.

03

Order the Whole Service Job

Impeller work may also need gaskets, wear plates, housings, drain seals, and lubricant. Check the full parts list before checkout.

Outboard Fitment Help

Part Number First, Engine Details Close Behind

Outboard service parts can look nearly identical while fitting different engines. When possible, search by the original part number. If you are not sure, send the Parts Desk the engine brand, model, horsepower, serial number, and photos of the part being replaced.

Ask Parts Desk Service Kits Maintenance Parts
Portable outboardsSearch filters, plugs, impellers, fuel fittings, props, and small-engine service parts.
Midrange outboardsLook for 40 HP to 115 HP service kits, cooling parts, fuel filters, and ignition items.
Offshore outboardsSearch Verado, SeaPro, Yamaha, Suzuki, Honda, and high-output service parts by exact model.

Outboard Motor Parts FAQ

Choosing the Right Outboard Parts

What details do I need to identify outboard parts?

Use the brand, model, horsepower, serial number, model year, shaft length, and the original part number whenever possible.

Are outboard impellers universal?

No. Impellers and water pump kits vary by brand, horsepower, lower unit, and production range. Match the exact engine application.

What is usually included in a 100-hour service?

Typical 100-hour service parts may include oil, filters, spark plugs, gear lube, drain plug seals, fuel filters, anodes, and inspection of the water pump. Always follow the engine maker's service schedule.

Can the Parts Desk help confirm fitment?

Yes. Send the outboard serial number, model information, photos, and any part numbers you have so fitment can be checked before ordering.
