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.
