I am sure that Bill Kinney will give you all of the details, but when doing your project, remember that Raymarine drives, and others, switch from one direction to the other by reversing polarity on the DC voltage drive units, linear and rotary.
The reason that I point this out to you is that the drive units need to be in sync regarding causing the boat to turn to port and/or starboard. The drive units on BeBe #387 are wired to the A/B switch with the linear the opposite polarity of the rotary because of the geometry of mounting the linear.
Also, remember that a 24VDC Raymarine Rotary or Linear drive will have a 12VDC clutch. This means that there are four wires going to the drive units:
- 12VDC positive to Clutch
- 12VDC negative to Clutch
- 24VDC positive in one direction, negative in the other going to the drive motor
- 24VDC negative in one direction, positive in the other going to the drive motor
If you can get your head around these points, the actual installation should be easy.
