    Lately seen a lot of cranks that have walked forward and rubbing on crank cases. I'm installing welded cranks from now on.

    Were there any warning signs before it let go, like any rpm loss?

    Yes I have been fighting rpm loss...I just thought it was from the hot weather...except when i went to one pitch less on prop I did not gain the 100 rpm's i usually get with this prop.....ordered all my parts and will be back in buisiness this month....so for now its ultra 150 time
