Get your boat’s maintenance ready for the water.
Make your next marine service a planned job. Find AMSOIL marine products, confirm the engine and gearcase requirements, and build a shopping list before the season gets busy.
Which marine oil should I choose?
Identify the engine manufacturer, model, year and engine type. Separate two-stroke and four-stroke requirements, then check the manual and current product applications. Engine oil and lower-unit or gearcase lubricant are separate decisions.
Prepare one clear service list
- Record the engine model and serial information needed for identification.
- List the oil or lubricant specification for each component.
- Check quantities, filters and the manufacturer’s service procedure.
- Note what was serviced, when and at how many operating hours.
Have a two-stroke application?
Confirm the product’s intended use and your engine’s instructions for injection or premix. Use the specified procedure and ratio where applicable. Bring the exact engine details if you need help locating the relevant product information.
Planning storage or a return to service?
Follow the boat and engine manufacturers’ procedures, including any fuel-system and corrosion-protection instructions that apply. Organize supplies with our seasonal equipment checklist.
