    Default have you ever?

    Anyone ever sheared the bolts that hold the driveshaft onto the PTO? I have had my newly built boat out about 5 times 5th time out I was showing off a little racing some boats. Laid into it hit some waves soo I let off ( cause I was in the air :S) and then when I laid into it again bang!! sheared all 4 bolts into the Pto. They were grade 3 stainless bolts but I am also wondering if it has to do with my driveshaft angle. any ideas? I just got the old bolts out cleaned up the threads and got grade 8 bolts for it! try again I guess!

    Your adapter/spacer is totally different than mine. My PTO is 4 allenhead countersunk, and then a 4 nut/bolt system.

    Also be sure you torque them. If they worked loose that could have been the issue. Grade 8 and locktight.

    The bolts they supply with those PTO's are crap, I wouldnt run them on anything other than a stock engine.

    I used RED once = huge mistake at take apart time.
    Used Blue from then on.
    And torque was as tight as I could get them with a breaker bar.
