I need measurements for motor placement and center ski pylon placement. Over the past few years I have been collecting parts to build a ski boat. I just acquired a 1991 ski Nautique hull. unfortunately it is completely bare, no motor mounts and the floor where the ski Pylon goes was taken out to repair the hull. Overall the hull is in really good shape. I just need measurements for the motor and ski pylon placement. measurements from the rudder hole to where the motor and transmission connect, and to the center of the Pylon would probably be the most accurate.
