The boating industry can be expensive for the typical weekend boater. That is, keeping, maintaining, and using a boat and all of its various accessories is a constant cost for the owner. In the Midwest and inland it is necessary to store boats and outboard boat motors out of the inclement weather and harsh conditions of seasonal change. Specifically, removing or installing an expensive and awkward outboard motor can be both dangerous financially and physically (damage or injury). It is not uncommon for motors to cost several thousand dollars.

The purpose of this project was to research, design, and implement a rugged, easy to use outboard motor mount that helps the user both install and uninstall their outboard motors in a safe way. It was imperative that the design be applicable to many outboard motor designs and handle the stresses caused by the use of these motors. By using 3D modeling software and sample boats and motors the designer was able to design and construct an effective solution to these problems.

This project resulted in a design that allowed the user of the motor to not have to induce a force of more than a third of the weight of the outboard motor, install their motor in less than 30 minutes while alone, and do all of this safely. Through frictional and torque analysis the designer was able to meet these goals and more, in this paper the process of the design, construction, and testing will be presented in detail.
