Not trying to jack a thread but that story made me think back a couple years.
Putting my boat on the trailer down in Shelter Island, San Diego, me and my buddy had a system. He would back the truck down while I stayed in the boat in the water. He would back in and I would drive on. He would get out, tighten the strap and off we go. Whole process takes like 20 seconds tops.
So the story goes, this guy watches us do it. Has his buddy stay in his boat, owner goes up and gets the truck, backs it down. Buddy sticks the boat in gear, swings the ass of the boat around and is now trying to back onto the trailer.
Attempts this 4 or 5 times before he realizes with his buddy (owner) is yelling from the back of the truck.
Probably the funniest sh!t I've ever seen. Oh yeah.... Lower unit and prop, fukced!
