Yea no doubt. Do a compression check, I did know a guy who had a a/c motor that would do that!

it is a/c engine only twin cylinder has 150 plus compression but is a few cylinders short so I take it the props don't spin on the larger engines I should be ok to lock the prop down from spinning thanks new to the game

A/C motors with allot of experience will very slowly turn when towed down the road, while providing continuing reliable service for a long time.

I don't really hurt anything that I have aver heard of. Prop turn 180 maybe every 10min or so. They aint like twirling going down the highway.

If using a 2 bladed prop, it is always nice to tie the prop vertically during towing long distances. This to keep the blades out of the wind as much as possible to save on gas.

Least that's how I have seen it regularly done in the past.
