Starting The Engine

Before starting, read the Pre-Starting Check List, Special Operating
Instructions, in the Operation Section.
Never start or run your outboard (even momentarily) without
water circulating through all the cooling water intake holes in
the gear case to prevent damage to the water pump (running
dry) or overheating of the engine.

water intake holes are submerged.

Open fuel tank filler cap vent screw (manual venting fuel tanks).
