Well, just to give an update in case anyone else is thinking about it, I put it on last night and lowered the motor to see how it held up over night. Worked fine. I took the boat out today to see how it did on the road. It seems to do what they say. The boat seemed secure and I didn't see any unusual bouncing of the motor going down the road. Really easy to put on and takes up no space to store. For $40 I am pretty pleased. We will see how it holds up long term. It seems to be made of pretty stiff rubber like material and has just a little give for about an inch when you lower the motor onto it.
