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.
Engine Oils
Marine gasoline, diesel, 2-stroke, synthetic, and OEM-approved oils help protect engines under load.
Drive & Gear Fluids
Gear lube, lower-unit oil, transmission fluid, and hydraulic fluid protect drives, gearboxes, trim, and steering systems.
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.
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.
