winterizing suzuki four stroke outboard

11 posts in this topic

I just got a new suzuki fourstroke (50hp) for the pontoon in mid-august and will be winterizing it for the first time this weekend. I have winterized my other two stroke outboards for years so I know how to do it.

I always use Stabil in my gas and unhook the fuel line while its running and just let it run out of gas before fogging the cylinders.

Someone recently told me that you are not supposed to let the fuel run out on a four stroke by unhooking the gas line as I have always done on my two strokes. Any advice on this?

I've heard of people leaving fuel in the carbs and not leaving fuel in the carbs, as long as the gas is stabilized by some manner.

The only concern I would have on any carb is drying out the seals by leaving them dry over the winter, but this wouldn't be any different for a 2 stroke vs a 4 stroke.

In my manual for a DF90 (90hp suzuki 4-stroke) it explains to run the engine at idle for 15 minutes to cycle the fuel stabilizer. Next spray the fogging oil in the air intake port on the side until the engine smokes while at idle, and then shut it down. After stopping the motor you're supposed to remove the plugs and spray fogging oil in each cylinder and turn the the motor over by hand. (I just turn the key with the kill switch removed). Don't forget to replace the oil, oil filter, and gear oil. According the the manual you don't have to drain it.

Thanks guys. Sounds like I can do pretty much like I always do with this motor. I left the owners manual at the cabin so I thought I'd put it out here so I could prepare myself if I needed anything special.

As always, a very helpful site!

I cant seem to find that manual.. Would fogging oil go into the side air intake port too? I just did it to the cylinders last year..

    • that is great!!!!   good for you guys!!!!
    • Your right rs_ld,  a full smoker is the way to go, leftovers can always be frozen and re heated..good eats.
    • 195 degrees on these butts. Like they say, if you are going to spend 9 hrs smoking 5# of meat, you just as well spend the same amount of time smoking 45#. The local grocery had these on sale so had a few friends take the offer to throw a roast on for them. Took two off early for slicing  Pulling the rest cost them each a beer though!
    • Very good stuff, kinda tasted like ribs with this recipe,  I'll keep at it til I find the right one!! Good luck moon lake!!
    • It will be interesting to see how the Warriors react in free agency.  Will they be able to keep the team together?  It seems like all these guys value winning above a paycheck so they might be willing to sign deals that will still allow the team flexibility to keep good role players around them.    
    • That's too bad.  The fish were ON FIRE up there.  I went out with my dad and uncle with our tiller walleye boat, and hardly a clue what we were doing, and we crushed them!  Ended up with 118 pounds of packaged salmon fillets.  I think I can honestly say it was the most fun fishing trip I've had in my life.  Here's my biggest of the trip, 25 pounds.    
    •   It's amazing to see a thoroughly talented team like Cleveland just get dissected like a back alley pick up team. I agree--GS will be THE team to beat for several more years if they keep their nucleus. I think we can make them sweat a little bit now, though, so that's pretty exciting for a change! 
    • dang I can see why anyone would slobber!!!!
    • Fletch's hands are totally tied by his own doing, keep in mind our 1st round pick this year was 15 games of Hanzal...definitley not worth it. Fletch needs to get off his duff and pull the trigger on a Scandella trade real soon for a decent Forward and not pass up an OK opportunity by "hoping" for the homerun and missing out on a good opportunity.  IMO our only hope is that other teams are "watered down" more than we are and that our vets can hang in there one more year.
    • Wondermous!!  Anytime, fivebucks! Years of workin' on that stuff does count for something!!!  I wish ya WOULDA bet me!!     Glad ya got 'er done!!!
