When I first saw your picture I was thinking you were going to use the VW to Motor Boat around the pond.
The original Beetles were able to float they were so water tight, or so I remember from back in the day.
When I was in the Navy, we were in Sydney, Au. in July 64. The local VW Dealer set one up with a shaft and propeller to be able to navagate in the bay for a promotion, Was pretty cool.
There is a guy down the road from us with a Beetle, and he was pulling a small Trailer with his Dirt Bike. Was zooming past us heading up in the hills.
