Boat Maintenance Kits

Due for scheduled engine service? A boat maintenance kit groups model-specific replacement parts in one package. DK Hardware carries kits for select Mercury, MerCruiser, Yamaha and Suzuki engines, including options for 100-hour and 300-hour service.

Start with your engine details and the maintenance schedule in its owner's manual. Then compare the kit's application and contents with the service you need to complete.

How Do You Pick the Right Boat Maintenance Kit?

Horsepower helps narrow the search, but it does not confirm a fit. Before ordering, check:

Engine brand and full model: Match the exact engine family and application, including whether it is an outboard, sterndrive or inboard engine.
Serial number and model year: Check the engine identification tag against the kit's listed fitment range.
Kit part number and exclusions: Read the full application details. Engines with similar names may use different filters or other service parts.
Service interval: Choose the kit that matches the work due under your engine's maintenance schedule. The contents are not a substitute for the manual's inspection and service checklist.

For example, the Mercury 8M0094233 300-hour kit is listed for 150hp FourStroke outboards with serial number 1B905505 and higher. Check that full application before selecting it for your motor.

What Comes in a Boat Maintenance Kit?

Contents vary by engine and service interval. These examples show why it helps to compare the individual parts list:

Kit example	Listed components
Mercury 8M0094233, 150hp FourStroke 300-hour kit	Oil and fuel filters, gearcase drain seals, four spark plugs, thermostat kit, water impeller kit, alternator belt and anodes
MerCruiser 8M0147051, select V6/V8 100-hour kit	Oil filter, fuel filter and gearcase drain seals. Check the listing's engine and filter-configuration restrictions
Yamaha 63PW006A0000, F150 100-hour kit	Water-pump components, thermostat, spark plugs, fuel filters, anode and other listed parts
Suzuki maintenance kits	Depending on the model, water-pump components, impeller, spark plugs, anodes and filters. Confirm the selected kit's exact contents

Check Fluids, Tools and Kit Contents

Do not assume engine oil or gear lubricant comes in the box. The Mercury and MerCruiser kits listed above specify that these fluids are sold separately. Check your manual for the required fluid specifications and quantities.

Compare your service checklist with the kit contents, then add any missing boat maintenance supplies and boat repair tools needed for the job.

Ordering Boat Maintenance Kits for a Shop or Marina?

Check availability and estimated dispatch timing before scheduling service. For multiple engines, confirm each engine's fitment separately and request volume pricing with the kit part numbers and quantities.
