Thanks Sean
I was able to trace the wires back and I have figured it out.
I have had some success with this project now, I have everything mounted on the boat and I have tested it (out of the water),
The auxiliary engine is following the main engine very nicely. I actually had to reduce the speed of the actuator as it was moving faster than the main, so it would start and stop every 50ms instead of moving smoothly along with the main.
I still have some zip ties and improvised angle brackets I need to replace with proper mounts but so far I am very pleased with how it works.
