Thx for all the help!
I'll definately get under it and check out the ground. Since I replaced the perfect pass it hasn't coughed once, but Id like to avoid future problems and know I have a good electrical ground.

My wife was pulling me behind it today and we hit something under the water. In my area of Oregon its almost certainly a log. afterwards anytime i throttle at more than an idle it starts to vibrate and gets worse the faster you go. fortunately i was close to the dock and pulled it out. the prop is new, and I can't see a single dent or ding in it. is it possible to bend the shaft without hitting the prop??
