5. Cold Temperature ‑ It may be helpful to prime the engine 1 to 3 times
using the manual primer knob before starting.
IMPORTANT: 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.

the fast idle speed feature to increase idle speed until engine is warmed
up. Keep engine speed below 2000 RPM.

approximate halfway (1/2) setting. After engine starts, immediately reduce
engine speed back to idle.

8. Starting Flooded Engine ‑ Advance the fast idle lever or throttle only
