This is the brain box. Dyno cable in, 12V in, guage output, reset zero button, bounce/delay adj knob. Mounts on transom. All the automotive weatherproof connectors. Also does the math to convert Tq into Hp.

One view. This is the Stellings piece found in the extension box. Normally there is a 1 1/4" gap between the backside of the flange and the bearing carrier. An universal bolts to one side with a shaft which bolts to the engine and the other side is where the bravo shaft goes into. Stock there is the flange and shaft going into the bearing carrier. It is on this shaft that I mount the strain guage in that 1 1/4" gap.

Side view. The strain guage and a few electronics are then sealed in the liguid black to harden and form the 'rotor' which is the donut like piece on the backside of the flange. It is fixed to the flange and rotates. It is the transmission of TQ thru the flange and shaft which is measures. Any shaft with TQ applied to it will twist slightly and this twist is what I measure and is propotional to TQ applied.

Another view. Right next to the rotor is the 'stator' which is attached to the bearing carrier. It is stationary and it provides power to the rotor and them picks up the TQ signal from the rotor. A cable comes out of it and runs to the control box.

Digital gauges sure. But I wanted to have white on white to match most every one's gauges out there. The resolution on my gauges is to about 10. Digital would have resolution to 0.01!

Marty, that is a 10. Is the connection inductive?
I will want to talk to you about making one to put on the back of our transmissions.
