OPERATION

Warming Up the Engine

Warm the engine at low engine speeds for about three minutes.

This allows the lubrication oil to circulate to all parts of the

engine, Operating the engine without warming it up shortens the

engine life. Be sure to check that cooling water is coming out of the

water cheek port when warming up the engine.

NOTE: If the engine is operated continuously without water

discharging from the water pump cooling water hole or idle hole,

the engine may overheat.

Starting The Engine

Before starting, read the Pre‑Starting Check List, Special

Operating Instructions, and Engine Break‑in Procedure in the

Operation Section.

Electric starting outboard models must not be started
manually using the starter rope, or run, without having the
battery leads connected to a battery. Damage to the charging
system could result.
