IMPORTANT: If no water is coming out of the water pump
indicator hole, stop engine and check cooling water intake for
obstruction. No obstruction may indicate a water pump failure or
blockage in the cooling system. These conditions will cause the
engine to overheat. Have the outboard checked by your dealer.
Operating the engine while overheated will cause engine damage.
Starting the Engine ‑ Tiller Handle Models
Before starting, read the Pre‑Starting Check List, Special
Operating Instructions, and Engine Break‑in Procedure in the
Operation Section.
NOTICE
Without sufficient cooling water, the engine, the water pump, and
other components will overheat and suffer damage. Provide a
sufficient supply of water to the water inlets during operation.
1. Make sure the cooling water intake is submerged.
