bracket question

[bdeep]

I have a 1974 20 center console with a yamaha f150 with a 20 inch shaft. It takes a fair amount of water over the back and I would like to mount a bracket and enclose the transom. Has anybody put a bracket on a 20 with a similar motor(440lbs)? As it is motor sits on the transom at it's original hight. Any insite would be appriciated.
