Mounting a 25hp Yamaha

[Rumbles1960]

I mounted my new Yamaha 25hp to my Grizzly Tracker which does not have any wood on the transom for the motor to rest against. The Yamaha has a couple of pointed bosses on motor support that now rest against the aluminum transom and actually keep the whole engine support from completely sitting flush against the transom. After my first test ride it seems as there is some minute movement between the two making a bit of a snapping sound. So now I wonder if I should be putting a piece of wood on the back of the transom for the motor to sit against, any thoughts?

I would put a piece of 1/2 inch plywood in there,seal it with water seal,and use 3M 5200 to caulk around it after everything is mounted.

Cabelas sells a rubber piece that wraps over the transom.
