    lots of raw fuel in the exhaust. lucky you weren't hurt.

    I had a resonator blow out as a result of a defective emm on a spring startup a few seasons ago..the whole affair ended up costing me a good customer

    new resonators are still available $125..just don't be shy with the4 sawzall cutting the foam out around the resonator In my case only a seam had split but it was just painful getting it all out and back in place. I had to take the reverse box out blah blah blah

    My resonator is right in the open on right hand side

    I doubt it's an emm issue..likely a sticky injector that flooded the engine

    if my memory serves the ski I dealt with was a 99..resonators buried.

    my issue came from trying to start a ski that had been badly flooded the week before ( due to the bad emm)

    not a bad idea to run a air blower into the exhaust to clear fumes before your next startup attempt..the water box could have lots of fuel in it.

    once the resonator was replaced, it was all good..the guy was being so difficult I told him "no charge"..with the silent and understood message "don't ever come back either"

    I take a much harder line these days with folks that leave out vital information when they bring a ski in for service.


    They say:

    started running bad and I have no clue why..it was just fine last time we had it out"

    what they didn't tell me...

    "my son put diesel fuel in the tank by accident..is that a problem?"


    They say:

    "The starter just goes click..no idea what is going on..was fine yesterday"

    what they didn't tell me

    "It was hard to start it after we launched it and didn't put the drain plugs in then my son spent an hour jump starting it with my duramax..then there was some bad smelling smoke and...."

    yup..I am working on a book....

    thanks,
    I have a resonator that fits
    I removed the emm....
    there are bubbles in the gel....
    I think my emm might be bad again???
    I never used it, it was in mechanic's shop last several months
    guess I am going to send it in again to check it out
    and also air out exhaust
    thanks,
    Mike

    Sounds like DFI either did not get the repair quite right, or perhaps one of the injectors has an electrical problem. Possible, I suppose, but not common.

    My suggestion is to talk to DFI and offer to send the two injectors along with the EMM. Mark them with the cylinder numbers before you remove them from the engine. If an injector is bad DFI can tell.

    bubbles in the gel are quite common and not a cause for concern. I always inspect emms after they are returned after I got one back two years ago that didn't have the gel applied over the repair area. It's two part stuff so mixing it can easily introduce air bubbles. Stale fuel can also set you up for a backfire, but to play it safe let dfi have a look if you can wait a few more weeks to get her in the water again.

    just as a reminder..do not fire an injector when it is not bolted to a cylinder head

    I called DFI today.....
    He said to send it back and he will take a look at it, and check it out
    also said that backfiring sounds like an EMM problem...
    Also said if there is bubbles in gel, it doesn't always mean that systems are bad
    oil or grease on components will make it bubble when they mix up gel
    I asked them about injectors last time, and he said just send it EMM
    so I am not sure if they check out injectors????
    anybody have them checked out?

    Have you ever had this one running? Is this the ski you had in for the new flywheel? Did it ever run since the flywheel replacement?
