Hey everybody. I was thinking to make the GPS guidance for my floating sauna. (Technically this can only be thought of as a big boat) I could do the control in the same way as in the example I found on the Internet. https://imgur.com/a/1fFaJ5Q In this example, is used a car air conditioning magnet switch to make traction on the shaft and, if desired also off. The windscreen wiper motor is used in the example. I thought I was using a high torque servo motor. Which solution would be better?
For throttle control, I was thinking of using two linear motors. One would handle the gear and the other would handle the throttle. As a autopilot hardware I planned to use Pixhawk 4 mini. Here’s a planned hardware.

Or maybe car windshield wiper motor and some driver for that ?2X https://www.ebay.com/itm/DC12-24V-20mm-500mm-Multi-function-Linear-Actuator-Motor-Stroke-Heavy-Duty-GK/371889646148?hash=item569659aa44:m:mdQwwa8_o2u5EGKbKgkAShg:rk:6:pf:0 for throttle and gear

I have some mechanics skills as well as electronics but no experience with ardupilot yet. So I would like you to question my plan and point me to right directon !
Thanks !
