A cheaper way
Unless you REALLY want to spend the money, there is a cheaper and, I think, much more effective solution. This is called a "Soft Patch" and I gleaned the idea from someone else, so I'm not really a genius. The "Soft Patch" consists of a bungee cord from the starboard stern rail seat support to the starboard rear side of the motor. This causes the back of the motor to go to the right. A solid line connection then goes from the left side of the motor to a 12 inch eyebolt that fits nicely in a hole on the tiller shaft. Adjust this line so that, when the tiller is centered, the motor is as well. When the tiller is moved to the right, the motor follows and vice versa. Attaching the "tiller line" with an open hook allows it to be disconnected easily when not in use. Now, when you are using the motor, turn the throttle handle up to almost ninety degrees so that speed adjustment can be easily accomplished by reaching back and twisting the throttle. Sure, reverse and neutral require bending backward, but it's so seldom that it's necessary to do either than I live with that. For pictures of this, go to www.geocities.com/opahay and look under projects. Like I said, it works very well for me for the last 3 seasons.
