Works fine then it will not pick up and motor vibrates. Replaced gas. If left to cool down after an hour or so will again work fine.

Do you have a question?

[dcrusha1]

what is the problem. why does it work fine then go into safe mode

motor will vibrate vigorously. water comes out of pee hole

[99yam40]

Just because tell tail has water coming out does not mean the motor is not overheating or if there is some kind of oil problem.
What are your gauges telling you and is the alarm buzzer sounding?

[dcrusha1]

gauges do not work

mechanic says it may be the power pack heating up.it will work fine until its on full throttle for awhile then it will only go slow, if I try to plane out the motor will shake violently. if it sits off for 45 minutes to an hour it will work again. can I use Freon to cool the power pack to troubleshoot to see if that's the problem
