spaz - what outdrives were you running? Composite, alum or steel? Were you running the one way or diff?
If you blew out the oneways, I don't think the pins would have helped. I usually blow them when I'm running the oneway and hit a dot - in the air the wheel is free-wheeling then when I hit the ground, all that momentum and spin of the motor slams on the outdrives. . .breaking the axles.
