Fitment Check

Match oil type, viscosity, specification, engine model, drive type, transmission model, and service interval before ordering fluids.

Ask Parts Desk

Use the oil, lubricant, and fluid specifications listed by the engine or drive manufacturer. Confirm viscosity, marine rating, capacity, filter match, and service procedure before maintenance.

Fitment

Use the Correct Specification, Not Just the Brand

Marine oils and fluids are selected by viscosity, certification, application, and equipment requirement. Check the engine manual, drive manual, transmission plate, or existing part number before mixing or replacing fluids.

Service

Fluids Tell a Story

Milky oil, burnt smell, metal flakes, dark gear lube, low fluid level, or repeated contamination can point to leaks, water intrusion, overheating, wear, or improper service.

Record hours, date, oil type, filter part number, quantity, and observations at every oil or fluid change.

OIL

Engine Oils

Marine gasoline, diesel, 2-stroke, synthetic, and OEM-approved oils help protect engines under load.

DRV

Drive & Gear Fluids

Gear lube, lower-unit oil, transmission fluid, and hydraulic fluid protect drives, gearboxes, trim, and steering systems.

GRS

Grease & Additives

Marine grease, anti-rust agents, corrosion inhibitors, and service additives support long-term maintenance.

Maintenance

Build Oil Changes Around the Whole Service

A proper oil or fluid service includes filters, drain plugs, gaskets, pumps, absorbent pads, inspection, correct disposal, and a final leak check after running the engine.

Change filtersReplace oil filters and seals when changing oil unless the service manual says otherwise.
Use clean transfer toolsKeep oil pumps, funnels, hoses, and containers clean to avoid contamination.
Check for waterMilky engine oil or gear lube can indicate water intrusion and should be investigated.
Dispose properlyUsed oil, filters, and absorbents should be handled as waste fluids according to local rules.

FAQ

Oils & Lubricants Questions

What oil should I use in my marine engine?

Use the viscosity and specification listed by the engine manufacturer. Marine gasoline engines often require NMMA FC-W oil, while marine diesels and OEM engines may call for specific diesel or OEM-approved oils.

How often should boat engine oil be changed?

Follow the engine manual. Many recreational engines are serviced annually or by engine hours, whichever comes first, and more often after contamination or severe use.

Is gear oil the same as engine oil?

No. Gear oil, lower unit lube, engine oil, transmission fluid, and hydraulic fluid are different products with different specifications. Use the correct fluid for the component.

Why is my gear oil milky?

Milky gear oil usually suggests water contamination. Inspect seals, drain plugs, gaskets, and pressure-test the drive or gearcase as recommended before refilling.
