You need to contact Baker Marine at www.scaryfast.com. You do not need an ugly grandpa planing plate, rather a nasty lookin' polished aluminum drag style planing plate. They do not extend out past the back of the motor, rather they extend off of the side of the motor (top of the gearcase is where it mounts) and they don't look bad. I am going to put one on my 19' tunnel this winter. Everyone I talk to says it helps tremendously in planing. Good Luck.
