[I'm guessing you are on the Fox Chain. Last Saturday the wind was brutal. We used to have a smaller 2 toon Sylvan. Once we got the JC tritoon it changed pontooning, we no longer fear the chop - though still don't enjoy super windy days. Wind coupled with the chop from the 38' offshore boats churning the chain water makes for an uncomfortable ride on any boat that can't get above the chop. Anyways...]
I used to winterize myself, I've done it over the years on many boats, but now w/o a trailer I have the marinas do most of my work. Here is my checklist developed over a long time. I used it for the 2001 Merc 40 HP oil injected 2 stroke we had on the Sylvan.
Requires:
socket set/spark plug wrench
prop wrench/chunk of 2x4 (wedge to assist in removing prop)
linesman pliers
needlenose piers
gap gauge
spark plug gap info. for engine
silicone spray
fogging oil
1 can Seafoam
new set of lower unit gearcase drain plug washers
new spark plugs (optionally)
grease gun w/ marine grease
drain pan
measuring cup (to catch gas out of bowl drain)
lower unit lube & pump
vinyl conditioner
plenty of rags
Steps to Winterize 2 Stroke O/B:
take boat for a nice 1 hr ride with 1/2 can of Seafoam in 1 full 6 gal. tank of gas
shut off engine at dock
pull cowl & plastic carb port plug. start motor, let idle
spray fogging oil slowly into carb port until engine dies (don't run oil injected motor out of gas)
disconnect fuel line at engine
raise motor
trailer boat & pull from water
------
lower engine all the way for 1/2 hr to drain all water (continue with steps below, thru "grease motor zirk fittings" as water is draining)
replace carb port plug
pull kill switch lanyard
mark plug wires order with permanent marker or tape
pull plug wires
remove spark plugs; inspect for condition. set aside or discard.
fog each cylinder
crank engine by hand by spinning flywheel (or giving key a quick turn)
re-fog cylinders
regap and reinstall plugs or install new, gapped, fresh plugs. dab clean oil on threads.
replace ignition wires
loosen brass drain plug on carb bowl bottom to drain fuel from bowl (use TBSP measuring cup to catch fuel)
tighten brass drain plug. do not overtighten!
lightly mist silicone spray over power head. AVOID ELECTRICAL CONTACTS.
replace cowl
------
place drain pan under lower unit
remove lower drain plug first, then remove top to relief pressure
drain lower unit lube into drain pan
fill with fresh lube from bottom port
replace top plug (using new gasket) first once case is filled and CLEAN LUBE comes out of top port (be sure to replace plug washers each lube change)
if old lube is milky white (contains water) or has metal shaving, further investigation into cause is warranted
replace lower plug using new gasket
grease all motor zirk fittings including cowl latch
------
raise motor
engage tow pin
remove battery; store in basement. do not set battery directly on concrete.
remove prop; grease shaft generously with marine grease. replace prop. tighten nut & insert cotter pin
cover prop with thick plastic bag and duct tape around it
Treat spare fuel tank with Seafoam & shake gently a few times
grease trailer wheels thru grease fittings using grease gun
------
remove & store indoors:
fire extinguisher
battery
1st aid kit
fenders (fenders will deflate in cold)
------
throw moth bags all around deck & under seats
wipe all vinyl generously with vinyl conditioner
cover boat
call for shrink wrap
DONE
Sounds like a LOT but it's really not. It's 2 hrs work total, and you have peace of mind. I promise you, if you pay someone they wont do everything above.
Some people change the gear lube after the winter. If there is ANY water inside you may be sorry you did so. One season we had water, because the drain plug gasket was old and hard and flat and let water seep in. Had we not found that in the fall, and it froze, and we used the motor in the spring w/o knowing - goodbye gears, hello expensive fix.
Antifreeze: some feel you should use a "beer bong" contraption on the dog ears to draw marine antifreeze into motor. That is so that if ANY water is trapped, it is treated. I never had a problem w/o doing this.
