I want to add a jackplate to my gheenoe classic but i dont like the manually adjustable ones on the market right now because you cannot asjust them on the water. I dont want the extra weight of hydraulic or electric rams, so i came up with a simple design to allow me to adjust my motor height quickly while on the water.
Imagine the simple bob's mini jack plate design. I want to make something similar but with a mechanism to lift or lower the motor easily. So in order to explain this, i need to first define the terms i am using to describe this.
The jack plate is made up of two halves, the back half that the motor mounts onto and the front half that attaches to the transom. These half slide up and down on four bolts that connect the two halves.
These four bolts will have large wingnuts of them so they can easily be loosened and tightened. The lifting mechanism is simple:
I will attach a plate to the bottom of the back half at a 90 angle, and one to the top of the front half at a 90 degree angle (see the conceptual diagram). A large square neck bolt will go through the centers of these two plates from the bottom. The square neck will lock into he bottom plate and the bolt will continue through the top of the top plate. A large lock nut will be put over the end and tightened until it contacts the top plate. In this design, tightening the nut on the bolt will lift the bottom plate up and therefor the motor. Losening the nut will lower the motor.
So all i would have to do to adjust the motor height is stop, losen the wing nuts, crank the motor up or down and retighten the wing nuts...
Has anyone every attempted something like this? Do you think it will work? Any comments or ideas would be appreciated.
