I've recently bought a 3.5 Honwave and spotted in the manual that it isn't recommended to trailer and tow the boat with the outboard attached. I find this odd as just about every SIB I've seen towed does, is this Honda covering themselves or is it really not the thing to do.

I tow all the time with my motor on, and use a spring loaded transom saver. When stored on the trailer, I put a cinder block under the motor then stack a wood pieces until the motor weight is transferred to the ground.
There are a couple of different styles of transom saves. As you can see in the photo above it is designed to fit over a roller. Mine is the same thing which I got for $15 so I modified it to work with my trailer which does not have a roller, so I built some brackets to keep it in place. Your trailer setup dictates the type you need to purchase.
