  • jackshaft balance

    I read somewhere on this forum a while back about a kit for balancing the jackshaft. I have a vibration at 3000 rpm none below or above that rpm.Could someone that has done this explain the procedure and tell where I might purchase the kit. Thanks!

    What motor and outdrive do you have? My boat has the the same vibration @ about 3050 rpm's. Just thinking maybe it might be related to something else,but more than likely thats probably the answer. I'm still under waranty and their suppose to come out and rebalance but I have not seen them yet. After they do it I will let you know if this remedies the problem.

      Don't worry about the vib. at 3000rpms., its normal. I had the same on my 25 and so did every other 25 owner I know in my area. If you get the vib at other rpm ranges, I would be concerned.
