I take mine off
I may be a bit risk averse, but I wouldn't trailer mine on the adjustable motor mount. I change the motor mount to a stronger Gaelick model on my O'Day 222, and even beefed up the backing substantially. However, I am afraid of stressing the transom while driving. I actually support mine in the forward section of the cockpit and then get some help lifting it on and off the bracket. I think the the mounting bracket on the tongue of the trailer is a good idea, and would like to see some pictures. Just my two cents worth. Best regards,Dave
