Don't speak too soon!
Tbh, you just need something that is approved by your insurer more than anything, and take a photo of it on to ensure you're covered in a claim.
If they want to steal it, they will. Chainsaws have been used on transoms and most lock nuts just get ground off anyway.
Other option is a tracker, then you and/or police can go get it. But it's a cost benefit scenario.
A newish 4stroke 140-250 is worth tracking as its a significant amount of money and left anywhere outside unprotected, will eventually go! It's what the bigger professionals seem to be after!
An old Yam 90 is prob the less professional outfits choice, so bolts etc may deter that type of criminal hopefully.
