hello Scott,
I remember mine is a Davis. I just looked it up in the WM catalog, where it is called a Motor Caddy. I remember I tried every which away to get it on. It was sewn where it had to slip under the motor by the clamp. It couldn't come apart to bypass the electric lift wires.

I will swear, therefor that the elaborate description in the catalog does not apply to the Yamaha hi-thrust 8/4.

There's another on the same page that looks just the same. Like you do, you have to leave them on if you unship the motor frequently. Obviously these harnesses should be designed to be put on the motor from the top.

Seems to me there should be a two part model made that has aa adjustable collar with D-rings on it that goes round the neck of the motor. It could be kept in the proper position with velcro dots And two, three or four adjustable straps with hooks on one end and loops on the other for the crane.

Why not invent something that people won't have to get p.o.'d at all the time!

Keep thinking I must have missed something
