Re: Apparently I'm not meant to have a boat...
Your two shots of the aft strap are a bit inconclusive.. looks to me that if the strap is on the shaft it is barely so, right at the exit point. I think the front strap was released during the 'drop'.. so operator error seems likely.
Closer photos of the suspect areas/alleged damage would be good!
