    Spark Plugs won't come out

    Sea Doo RXP. Have never changed the plugs since I bought it new in 2006. probably has 50-60 hours on it. Had 1 year old gas and not running good, so figured I fouled the plugs. Used the plug wrench that came with it and deformed it so it slips. Went to the local dealer bought another one, looked stronger, deformed it as well. I shot Liquid Wrench into the area and left it overnight, still nothing, all 3 won't budge. Going to buy a a heavier duty 16mm socket that fits and try that, Am I missing something? Are these things threaded backward to what I am used to, or just froze? Not a idiot, but feel like one today

    You should start you motor, let everything get nice and hot, then remove the plugs. Pulling them cold can result in a broken plug

    Pulling the plugs hot can result in striped threads. There's a product available, a spray type, which super cools the item to be removed or try penetration oil.

    Let some liquid wrench soak in there overnight, get a real spark plug socket and a 1/2" drive ratchet on those bad boys and pray you don't mess up the head.

    a real spark plug socket is a must!

    most certainly some liquid wrench penetrant and time. you bust a plug, i's going to be a far longer affair.....

    and these plugs cheese off rather easily

    a senior member with 1500+ posts and the best you can do is be critical of a new member? really?

    Frankly, I would have had something to say about the year old gas IF he had complained of poor running. This was plain and simple..stuck plug(due to no routine maintenance)

    now of course if somebody is being an asshat......

    warming a motor up before pulling a plug is. I said nice and hot, but thats a relative term. Start the motor for 20 seconds and the go for it.

    Really? I didn't mean to hurt his feelings or yours. When someone owns a ski for 8 years and doesn't perform any preventitive maintenance and then asks for advice. What do you think the kind of response that will come from a senior member that changes plugs, oil and pulls his pump every year and has over 500hrs on his ski. You want a tissue.........
