11. Push in the primer/idle speed knob after engine starts. If engine begins to
stall, reprime until engine is running smoothly.
NOTE: Starting flooded engine ‑ Push in the primer/idle speed knob and turn
full clockwise. Continue to crank the engine for starting.
12. Turn the primer/idle speed knob counterclockwise to obtain desired idle
speed as engine warms up.
13. Check for a steady stream of water flowing out of the water pump
indicator hole.
NOTE: Engines equipped with a thermostat ‑ The amount of water flow can
vary due to the thermostat operation. It may take several minutes for the
engine to warm up enough for water to start spraying out of the indicator hole.
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 serious engine
damage.
