140 Johnson 4s for 20 cc?

[riffraff]

I found this picture of how I would like to rig my boat...it has a bracket and fully glassed transom. Do you think I will have to raise the floor? My intent is to use a flotation bracket. I should contact Jwilliams and pick his brain! Blackfin, how fast is plenty fast??
