Fogging EFI????

[chpthril]

i live in texas and we are still out on the lake about every other week.. my boat will probrably sit less than 3 months.. do i realy need to winterize or can i use some good fuel stabilizer and be ok.

In your case, dont call it "winterizing" but call it an annual winter service.

Like Dog said, you will still need to drain the water after each use so it wont freeze if you get a cold snap. A few shots of fogging oil wont hurt either, just dont need to use as much as someone who is going to put it up for 5-6 months.

Other then that, change the fluids, lube the steering and throw in a new impeller in the spring.

Where he and I are at it's not too humid at all.

well i keep my boat in m shop and its insulated... so i dont know if i am realy cooncerned with it freezing.. and if it does get cold then i can just run the heaters in there.. i was more concerned with the fuel getting all gummy and stuff

Oh yeah, with it stored indoors, no fear of freezing. Must be nice. Maybe when I grow up, i'll have a garage to store my toys in.

I would just do the other yearly services and throw in some stabilizer and say "see ya"

Chptril,
When you grow up get a "toybox/garage" like Ragboy has!
He wins the "Pimpiest boat storage unit" award hands down.

I usually use fogging oil like everyone else here, but recently have read a few threads on various sites referring to the use of 2 stroke oil instead.
It’s said that this lubes both the fuel track and the bores themselves, and is a method used by numerous dealers, and approved by Chaparral ( mentioned in their Forum).

BoatsUS also mentions this :
What my manual says, and what I do is remove the fuel filter, and mix in about 4 oz of 2 cycle outboard motor oil. I then reinstall (careful not to spill any...fuel in the bilge is an explosion waiting to happen). Re run the engine for about 5 minutes or until you see blueish smoke. Remove and replace the fuel filter with a new one.

What do you think?

Dont know off the top of my head what kind of additives are in 2cycle oil, but he first thing that I would worry about would be some kind of cleaning additive that may be corrosive to the injectors that are designed for gasoline/gasoline additives only.

Now, as far as using this method. First, the injectors are so close to the heads, the entire intake will be left unfogged. No big deal as most engines have alum and plastic intakes, and they dont rust. In theory, we are talking .5 oz per cyl diluted by maybe a pint of fuel between the filter and fuel rail. As soon as you start to crank the engine, the pump starts to pump more fuel into the system and any unused fuel, highest quantity is at idle and containing our 2cycle oil, is returned to the tank. An engine needs the least amount of fuel on deceleration, fallowed by Idle. With the injector "on time" being so short at idle, I think we would have such a small amount oil/fuel per combustion event, that I'm not sure you would ever see any oil smoke.

I also like to run the engine after I change the filter so it fills up with fuel, containing the stabilizer already in the tank, and not left empty all winter.
