Starting The Engine (Continued)
5
Shift outboard to neutral (N) position.
6 The engine can be manually primed by pushing in on the key
choke switch (if so equipped) or a remote choke switch can be
connected to the yel/blk wire at the engine harness connector.
(Refer to wiring diagram).
Note: Starting Flooded Engine – Advance throttle to at least 1/2 open
(gear case in neutral), and crank engine for 10 seconds. Wait 30 se-
conds and repeat until engine starts.
7 Check for a steady stream of water flowing out of the water pump
indicator (tell-tale) hose.
IMPORTANT: If no water is coming out of the water pump indica-
tor hole, stop engine and check cooling water intake holes for
obstruction. If no intake obstruction is found this may indicate
a water pump failure or internal 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.
