Important Information

IMPORTANT DAILY INSPECTION BEFORE EACH USE

Any outboard mounted on the boat must have the mounting hardware

inspected and checked to ensure that the hardware has not become loose. A

decal on the transom bracket reminds the owner to check the fasteners

securing the outboard to the transom before each use.

Decal on the transom bracket

BEFORE STARTING THE ENGINE

NOTICE

Lack of oil pressure in the system can cause severe internal engine damage

during start‑up. Prime the oil injection pump on new or rebuilt engines or after

performing maintenance on the oiling system.

Refer to 

Outboard Installation 

 Priming the Oil Injection Pump

 for

instructions.

FUEL REQUIREMENTS

Do not use premixed gas and oil in this engine. The engine automatically

receives extra oil during engine break‑in. Use a fresh supply of the

recommended gasoline during engine break‑in and after engine break‑in.

OIL RECOMMENDATION

Recommended Oil

OptiMax Oil or Premium Plus 2

Cycle TC

W3

Outboard Oil

OptiMax Oil or Premium Plus TC‑W3 is a higher grade oil that provides
