WARNING
To avoid possible injury when flushing, remove
the propeller. Refer to Propeller Replacement.
1. Remove propeller (refer to Propeller Replace-
ment). Install the flushing attachment so therub-
ber cups fit tightly over the cooling water intake
holes.
2. Attach a water hose to the flushing attachment.
Turn on the water and adjust the flow so water is
leakingaround therubber cupsto ensurethe en-
gine receives an adequate supply of cooling wa-
ter.
3. Startthe engine andrun itat idlespeed inneutral
shift position.
4. Adjust water flow (if necessary) so excess water
continues leaking out from around the rubber
cups to ensure the engine is receiving an ade-
quate supply of cooling water.

Storage
The major consideration in preparing your outboard
for storage is to protect it from rust, corrosion, and
damage caused by freezing of trapped water.
Thefollowingstorageproceduresshouldbefollowed
to prepare your outboard for out-of-season storage
or prolonged storage (two months or longer).
CAUTION
Never start or run your outboard (even momen-
tarily) without water circulating through all the
coolingwaterintakeholesinthegearcasetopre-
vent damage to the water pump (running dry) or
overheating of the engine.
Fuel System
IMPORTANT: Gasoline containing alcohol (etha-
nol or methanol) can cause a formation of acid
during storage and can damage the fuel system.
If the gasoline being use contains alcohol, it is
advisable to drain as much of the remaining gas-
oline as possible from the fuel tank, remote fuel
line, and engine fuel system.
Fill the fuel system (tank, hoses, fuel pump and car-
buretors)withtreated(stabilized)fueltohelpprevent
