Crankcase Oil - Inboard Models

To help obtain optimum engine performance and to provide maximum protection, we strongly recommend the use of a quality 4-cycle marine engine oil. If not available, a good grade, straight weight, detergent automotive oil of correct viscosity, with an api classification of sg/cd ii, may be used.

At ambient temperatures below 32° F. (0° C) sae 20w is advisable. In all cases a quality 4-cycle marine engine oil is preferred.

IMPORTANT: The use of non-detergent oils, multi-viscosity oils (other than 20w-40 or 20w-50), low quality oils or oils which contain solid additives specifically are not recommended.

Oil filter should always be changed with oil.
