Hello! I have a J/30 sailboat with a transom-hung rudder and the EV-100 tiller pilot. I'm considering adding the M81105 rudder reference sensor to maximize performance of the autopilot.
I'm wondering if there are any issues mounting the sensor on the transom (high enough that it will not submerge when heeling of course). I know these units are typically installed belowdecks.
Mounting above decks isn't recommended but, we do have installations where it is needed. There is a bottom plate on the Rotary Rudder reference unit, and if you remove fill the open area with RTV or Silicon sealant, it will protect the pcb within, then remount the plastic plate.
