Part 3 of the Gator Conversion Kit is the Turbine part. Simply glue it to the back of the boat, just below the ejector lip for the waterbomb. Make sure you don´t accidently hinder the articulated ejection mechanism. Attention! Once glued on, there is not enough clearance anymore in the back to fit the boat into the Jeep, so you need to carefully trim the back of the black chassis.
