Well that backfired (prop guard bent prop)

My driveway slopes down at about a 30 degree angle, which makes a nightmare trying to get my boat trailer in the garage. Previously, I've used a 8" drop hitch and 2x10's get the prop gaurd to clear the toe of the slope. This year, I decided to bolt some trailer wheels to the bottom of the prop guard which would lift the trailer up at the toe of the slope. Well, the wheels did their job, until I noticed the prop guard deflected so much that it pushed agianst the prop and bent my new Acme 911 prop
