Connection to the water propulsion drive. The rounded end of an edge-on bossless Pawl is visible between the 1½” × 1” Corner Brackets. The Corner Bracket assembly slides on a Long Threaded Pin and the linkage is then traced to a 3½” Crank Handle on the lower left where it drops behind a right-hand chassis member then runs to the cab. After the Chain, 26t Bevels send the drive to a propeller on each side.
