    2000 xa 1200 y

    I am at the lake and today my jet ski has a loss of power at full throttle it normally goes about 50 and won't get over 30 mph I have checked the spark plugs and put in new ones but no change. I pulled it out of the water and checked the intake but was ok. I haven't checked the gap on the plugs but it started doing it while I had the other plugs in. Any help would be greatly appreciated. Paul

    check compression first and make sure they are all close to the same reading

    if thats fine the catalytic converter may be clogged
