Bought this to put in my boat tool box. Takes up less weight and space than a 2x4. Actually had to use it on a trip when a bunch of fishing line got tangled around prop and shaft. Worked great. No busted knuckles trying to hold it in place and stayed put.

This worked exactly as it was supposed to on my Mercury 9.9 hp outboard. More convenient that trying to balance a wooden block.

It doesn't keep the propellor from rotating!
