I had my 2001 2 stroke Yamaha stolen in 2001 4 months after I put it on! I had a bar lock across the clamps, and I didn't see any damage to the lock.... I think they knew how to pick locks or had a master key, the boat and motor were right beside my master bedroom and I have 2 labs that didn't hear a thing or they would have barked....go figure. I now have my new 8 hp bolted and welded no probs yet.

I learned a lesson the hard way from my insurance company I didn’t have enough coverage and it cost an extra grand for a 4 stroke since Yamaha quit making 2 stroke 8 hp.

The big lesson that I learned was make sure if you have your boat insurance through your home owners that it's not a rider with the same policy # or it counts against the # of claims on your home owner’s policy... Case in point, we had an electrical fire in our stove and it and the floor had to be replaced about $1400. And the motor claim was $1200. My insurance company gave me a notice of non renewal because of 2 claims on my home owners insurance in 5 years after I had been with them for 14 yrs. with no other claims, all insurance companies are tightening up there belts and dumping policy holders for as few as 1 claim. They call the small claims like mine nuisance claims and mark you as high risk and my insurance doubled with these 2 claims, best I could find after talking to 10 different companies. Good Luck keeping the motors on without them being stolen!
