Construction of the drive train began at the rear strut since this section is highly integrated with the entire
rear hydrofoil. As mentioned in the previous section, gearboxes are located on both ends of the rear strut.
For this the gearboxes were salvaged off of small outboard motors and welded to either end of the strut.
A drive shaft then travels through the rear strut connecting the two gearboxes. A shaft coupler is located
at the upper end of the drive shaft so that the entire rear hydrofoil can be detached from the watercraft.
From here the portion of the strut above the detachment point, including the upper gearbox, was welded
to back end of the center tube. This welded connection is shown in Figure 33 below. Also the completed
strut assembly is shown in Figure 32.
