If you are doing your own winterising and perhaps servicing.. I would advise getting hold of a manual for your engine. There are plenty of links for various manuals on the internet and also on this forum. They appear to be “free manuals”
In my owners manual for my outboard..and I got it free from the manufactures site..below is what it tells me to do. I don’t know what is best for your engine.. it may be the same..but with a work from yourself.. I think you will find what your engines manufacturer recomments ?
Hope that at least helps some
As a safety precaution, when boat is in storage,
remove positive (+) battery cable. This will eliminate
possibility of accidental starting of engine and resultant
overheating and damage to engine from lack of
In preparing an outboard for out-of-season storage, 2 precautions
must be considered: 1) The engine must be protected
from physical damage and 2) the engine must be
protected from rust, corrosion and dirt.
1. Remove cowling from engine.
2. Place outboard in water or install Quicksilver Flushing
Attachment over water intake by following instructions
outlined in “Flushing Cooling System” (see “Table of
3. Start engine and allow to warm up. Disconnect fuel
line. When engine starts to stall quickly spray Quicksilver
Storage Seal into each carburetor throat. Continue
to spray until engine dies from lack of fuel.
4. Remove spark plugs and inject a 5 second spray of
Quicksilver Storage Seal around the inside of each cylinder.
Manually turn engine over several times to distribute
Storage Seal throughout cylinders. Reinstall
5. If engine fuel filter appears to be contaminated, remove
and replace. Refer to Section 3 “Fuel System
6. Drain and refill lower unit with Quicksilver Gear Lube,
as explained in “Gear Housing Lubrication” (see “Table
7. Clean outboard thoroughly, including all accessible
powerhead parts, and spray with Corrosion and Rust
8. Refer to lubrication chart in this section (see “Table of
Contents”) and lubricate all lubrication points.
9. Remove propeller. Apply Quicksilver Special Lubricant
101, Anti-Corrosion Grease or 2-4-C Marine Lubricant
to propeller shaft and reinstall propeller. Refer to
“Propeller Installation” (see “Table of Contents”).
IMPORTANT: When storing outboard for the winter, be
sure that all water drain holes in gear housing are open
and free so that all water will drain out. If a speedometer
is installed in the boat, disconnect the pickup tube
and allow it to drain. Reconnect the tube after draining.
Trapped water may freeze and expand, thus cracking
gear housing and/or water pump housing. Check and
refill gear housing with Quicksilver Gear Lube before
storage to protect against possible water leakage into
gear housing which is caused by loose lubricant vent
plug or loose grease fill plug. Inspect gaskets under
lubricant vent and fill plugs, replacing any damaged
gaskets, before reinstalling plugs.
