Description

Building a custom jet boat for river cruising is an involved project. The main component of the boat is the drive train; including the engine, intake, and impellor. A Kawasaki Jet Ski was provided for disassembly and major components. The engine, impellor, drive shaft, control system, and other components will be used from the Jet Ski to construct the jet boat. This senior design project focuses on designing and implementing the drive train using the existing engine, impellor, and drive shaft. To accomplish a safe and reliable operation an intake, motor mounts, and couplings must be designed and fabricated. Other components for integrating the drive train to the existing aluminum boat hull must also be fabricated and welded into place. An analysis of vibrations, stress, and other engineering concerns were addressed for components as well as the drive train. Finite element analysis of the boat hull and drive shaft were performed to ensure stability of the system. To ensure a safe design, testing of drive shaft alignment, welds, and bolts will be completed prior to operation. As an ongoing project, implementation of control systems, accessories, cosmetic components will be completed at a later date.
