hey, i took the waverunner out last weekend, it was running pretty good. shut it off a couple times and fired right back up. well about 30 minutes after running, i let go of the throttle and it slowely idled down and died, and when i tried to start it, it would not turn over, it would just click. battery is fine, tested it and charged it. I have taken the plugs out(the first plug was corroded pretty bad) the rest seemed ok. and with the plugs out, i tried turning the dirveshaft by hand with a wrench on the impeller, but i couldnt budge it either way. am i supposed to be able to turn it by this? i have not checked the starter relay or selenoid, but ive doen some reasearch, and tried to turn the engine over by hand wich i cannot do with shaft. Could my engine be siezed up? or could it be in the gears? is there a better way to check if it is siezed? i jsut baught it and do not want to spend more $ at the shop getting it fixed. any help is appreciated.
