Engine Oil Recommendations
We recommend the use of Mercury or Quicksilver SAE 10W-30 multi-viscosity 4-Stroke Outboard Oil for general,
all-temperature use. If SAE 25W-40 multi-viscosity oil is preferred, use Mercury MerCruiser 4-cycle engine oil or
Quicksilver sterndrive & inboard 4-cycle engine oil. Never use 4-cycle engine oil that is not certified to meet or
exceed any one or combination of the following American Petroleum Institute (API) Service Classification SH, SG,
SF, CF-4, CE, CD, CDII. Severe engine damage may result from use of an inferior oil.
Recommended SAE Viscosity for Engine Oil
a - SAE 25W-40 viscosity oil may be used at temperatures above 4 °C (40 °F)
b - SAE 10W-30 viscosity oil is recommended for use in all temperatures.
Checking Engine Oil
IMPORTANT: Do not overfill. Be sure that the outboard is upright (not tilted) when checking oil.
1. Position the outboard vertical and remove the top cowl.
2. Remove the oil filler cap. Wipe oil off the dipstick and screw the oil filler cap back into the oil fill hole completely.
Remove the oil filler cap and check oil level on dipstick. Oil must be between full mark and add mark. If oil
level is low, add oil to bring level no higher than full mark.
NOTE: If oil level is at the add mark, add 100 ml (3 oz.) of oil.
IMPORTANT: Inspect oil for signs of contamination. Oil contaminated with water will have a milky color to it; oil
contaminated with fuel will have a strong fuel smell. If contaminated oil is noticed, have the engine checked by
your dealer.
