My Yamaha 150V tachs.

Another question I have is should I also install a Transom Mounting Bracket Plate before I put the motor on for stability? Its seems to me that it would add extra strength to the transom. Would there be any drawbacks to doing this?
I was also thinking of adding some Transom Support Plates on the inside of the boat. With both the bracket and the support plate, I would be adding another
5/8" to the length of the transom bolts. Would this make a difference? Has anybody done this?
