    Spark plug coils keep popping out

    2012 seadoo gtr 215 modded. For some reason my coils keep coming off of my sparkplugs. Any ideas why

    Are you using the correct plugs that the cap must be screwed off?

    NGK DCPR8E #4339 With cap removed!

    Is there oil collecting as well in the spark plug tubes?
    Remove valve cover and see if the seals from spark plug tubes are seated properly.
    Seen it first hand happening once.
    Otherwise big zip-ties

    Go with the 300 valve cover and coils. The coils are bolted down and you can use the same spark plugs with the caps on instead of removed. Works great.

    I just had the coils replaced on my '17 RXT (again) under warranty because they wouldn't stay in place. The reason I was given is that the spring that grips the threaded tip of the spark plug gets worn and loses the gripping ability. There's really no way to prevent the wear so they need to be replaced periodically.

    Those ignition coils are very expensive vs the new 300 coils. Get a 300 valve cover and 3 used ignition coils. The sparks use the same ignition coils as the 300s or from quite a few older suzuki cars/suvs.

    Remove sparkplugs look down inside the sparkplug tube where the plug threads. The area around where the plug threads in should be be clean and shiny aluminum. What happens is water gets in around the coil sits around the sparkplug and causes corrosion when a new spark plugs is installed the corrosion keeps the crush ring of the plug from sealing against the head letting compression into the sparkplig tube creating pressure pushing the coil out.

    Spark plug not seating/sealing properly, and leaking compression.

    My coils are so hard to remove it hurts my fingers doing it. Always wondered how people manage to pop them.
