I made it against rules. They advice to remove prop before.
I have used some cheap plastic pond (cheap but good - after season sale)
Main idea was to avoid noise. In water E-tec sounds fantastic, without is noisy.
I have used ICON gauges (RPM).
1) Stabilize the engine’s fuel supply. Add 2+4
Fuel Conditioner following instructions on
container. Fill fuel tank.
2) If winterizing on a trailer, remove the propeller.
Attach a garden hose to flushing
port and turn on the water. Refer to Flushing
on page 46.
3) Outboard must be in NEUTRAL, and remote
control and shift linkage must be in
NEUTRAL position at all times during winterization
To winterize the engine, enter the SYSTEM menu, then:
1.) Use the UP or DOWN buttons to select WINTERIZE.
2.) Press and hold the MODE button to enter the selection.
The LCD screen will display message "PERFORM WINTERIZE?".
3.) Press and hold the MODE button to enter WINTERIZATION.
The LCD screen will display the message "RECEIVING DATA TO START
4.) When prompted, engage NEUTRAL only button on throttle and
advance the THROTTLE ONLY to at least 50%.
The LCD screen will display "WINTERIZE IN PROGRESS".
When complete the LCD screen will display WINTERIZE COMPLETE.
Do not adjust throttle or engine until winterization is complete and the
engine has shut OFF
A few minutes, full automatic process. Engine has stopped automatically on the end of process. Now she left to winter sleep
