getting winter storage lubricant into the cylinders

[fastback4]

Do I need to run my 2007 90 horsepower 2-stroke Yamaha engine to get lubricant into the cylinders for winter storage. I've treated my fuel for winter storage already. This is my first Yamaha engine but in the past on my older Mercury Motors I've used a spray bottle with full strength seafoam gas treatment, cranked the engine, not started, and sprayed seafoam gas treatment into each cylinder about 4 shots each. Any feedback on this procedure will be appreciated.

Did you buy the fogging spray? I believe the directions are to run it. Hopefully the valves, etc get some benefit too.

I do not use the foaming seafoam. I use seafoam gas treatment full strength and apply it with a plastic spray bottle. 2 stroke engines use reeds not valves and I'm quite certain the reeds and piston rings are getting sufficient coverage.

no they do not.
reeds can corrode.
wristpins,crankpins and all the other shiney metal parts can rust.
MUST do it through the intake system.
seafoam is NOT a long term storage oil.
buy a can of fogging oil.
remove the air box.
start the engine and allow it to warm up making sure adequate water is supplied.

now move the warm up lever to get about 1100 RPM.
spray about 1/2 the can equally in all the carbs.
idle it down shut it off and that part is done.
the only two reasons to winterize a two stroke outboard are 1 protect the fuel system.
2 to protect all them thar close tolerance shiny metal parts inside.

2 stroke, brain fart.....

RB, I recently read somewhere on this forum.

For 2 stroke internal lube/storage, to open up /disconnect linkage and let the oil pump run wide open (extra oil) to lube up the lower end as well...

Yea, nay?

I have done that in a pinch.
we had a few customers at salty dawg marina that did not use the boats much.
that is what we did before putting them back in the stack.

Where is Salty Dawg Marina?

[rodbolt17]

salty dawg that I worked at used to be in Manteo NC.
it is now condos.
we had roughly 300 boats in the dry stack and about 60 or so in outside racks and about 30 in slips and I was the only tech.

I stayed rather busy.

salty dawg was a shamrock dealer,yamaha dealer and a Volvo dealer and a mercrusier dealer.

10-4. Never heard of it. That explains it.

Ok, that makes sense, not a full on winterize but extra protection easy and free...Tks..

Fog the engine as Rodbolt says, cant go wrong.

Just say NO!!!

I'm in SW Florida, there is NO winterizing when mid winter it warms up to mid 70'sF, water temp about the same..

It's about 82F right now and sunny.

[rodbolt17]

yep
shiny machined iron castings and machined steel parts never rust while sitting in FL.
never saw a rusty brake rotor in Pensacola nor mobile al.

Not sure where this OP lives. I don't winterize. Cold day here is 48 degrees. Run the boat couple times a month to keep batteries charged. 70 here, perfect.
