Instead of fogging??

[babikov]

Instead of fogging into carburator, why not to remove spark plugs and spray directly into cylinders? I see the following advantages: I don’t have to start the boat, no muffs, hose, no water and oil on the driveway, etc. Also, I am sure that every cylinder got a definite amount of oil. Disadvantages of fogging into carburator: sometimes the engine dies too soon (bad), sometimes does not die at all (bad). I know that one can play with RPMs, but this is a hassle! Why not to remove spark plugs and spray directly into cylinders?Thanks for your input!

Engine: 4.3 LX/V6 Alpha One Balanced Shaft/Thunderbolt IV Ignition, 1993, serial number 0F024564

Ayuh,.... Why fog/ oil at All,.... My motor is down, maybe 6 months,...

So what, it don't rust in that amount of time,...

Foggin' oil is for mothballin' a motor for Years, 'n Years,.... Not a few months,...

A marketin' strategy by Marine retailers,... like usin' Antifreeze for winterizin',...

All marketin' hype,....

Dear Bondo,
I think I did not write my question carefully. I had to go back and edit it. Yes to fogging, of course, but why not to spray directly into cylinders, instead of the carburetor’s air intake. Please, reflect.
Thanks.

Ayuh,.... Same answer,... it's Un-necessary, unless yer layin' up the motor for Years, not a few months,...

But hey,... It's yer boat, 'n if ya feel the need to squirt oil into, or for that matter, onto yer motor,...

Go right ahead,. it won't Hurt a thing,...

No upside, nor downside to yer through the plug hole oilin',...
though if yer goin' through the effort, turn the motor over a few times to distribute the oil film,....

fogging via the carb intake on a running engine also fogs the valves / valve seats and on a two stroke carbed engine also the crankase. fogging directly into the cylinders it fogs only them.

beyond that i,m fully with bondo. i personally never fogged an engine, outboard or inboard, and never ever had any issues next season.

best regards .

Re: Instead of fogging??

If you have a fuel injected motor you have to fog via the pull the spark plug method as the computer will not allow the motor to stall. I tried to fog one year on my 4.3 MPI and realized that it was a useless venture as the motor would keep on running and burn off the oil and I did not want to pull the plugs.

I have fogged motors that sit outside. If stored inside, even unheated, then I will pass on the extra work. But outside, with the temps swinging from -45 to -10 fogging can prevent stuck rings. But our boats sit for 10 long months.
When I was a kid, our two stroke bikes were usually stuck by spring time.
