    Storage with Compressed air

    According to BRP storage procedure 2010-7, Air can be used instead of anti-freeze to protect the exhaust system. Can this be done with engine off, or will it blow water into the engine when air is injected into the flush port. ?

    use antifreeze, air will prevent freezing but wont help against corrosion.

    Also the compressed air will not get all the water out of the water box. Use antifreeze. Add until when running blows some out the exhaust if you blip the throttle.
    I always pull the sparkplugs, spray in some marine storage seal, crank the engine at WOT (to turn off injectors) and reinstall sparkplugs with a light coat of antiseize on the treads.
    Don't forget fuel stablizer in any remaining gas. (first step to be sure it get ot injectors too)

    Kinda wanted to know if the compressed air will blow water into the engine when its not running. I blow the water out first then put the antifreeze in . This year I did not have the engine running for some ransom when I did the procedure.

    There won’t be enough residual water left in the hose or manifold to make it into the engine.

    That's what I was hoping. I ended up pulling the plugs and cranked it over, no water came out. I fogged some storage oil into each cylinder. Used a drinking straw to get the oil in the plug hole, and keep the hole area clean.
