Can I make my own throttle control w/ a potentiometer

Can I make my own throttle control w/ a potentiometer

I’m in the process of adding my new 2016 Honda 9.9HP kicker engine to my homemade dive platform (still under design and construction).

I want to electricalley control the throttle from inside pilot house.

Can I obtain the servo http://www.iboats.com/TrollMaster-Servo-Kit-TrollMaster/dm/view_id.887115?cm_mmc={cmids}

Example I won’t spend a dime at this iboat site.

Then use a potentiometer to control it like are the controllers work off resistanse correct?

Anyone here own a https://www.amazon.com/CONTROLLKING...0032N03P4/ref=cm_cr_arp_d_product_top?ie=UTF8
That can mearsure the resistance values at closed throttle then at WOT.

Thanks TB

While the product in the link shows a potentiometer there is waaaay more to the system. What is not shown is the electrical actuator/motor and control electronics that attaches to the tiller for which this box is the control head. The price shown is not for a "potentiometer in a box". I have a degree in electrical engineering and would not attempt to build this myself for a one off....unless I had nothing else to do for a couple of weeks.... and was bored.
