Put a piece of wood on the bottom of the boat as a straight line & check how close it is to the anti cav plate. Shhould put it even or a little below. remember as the water passes under the boat the boat makes an imprint in the water as it runs lower than the top. As the water passes out the back it quickly comes back up to the lake level & the cav plate will be underwater even if it is equal to the bottom of the boat. I use a 1" x 3/4" piece of wood under the motor to raise the motor a little but be sure the clapms still get a good bite on the transom & not go too high. Use a chain to keep the motor to the boat even if it falls off, cheap insurance!!
