I am with David. I would caution and suggest you do proper investigation before you venture in that direction. Talk to Raymarine
, they are quite helpful.
The linear drive
unit also has the clutch
connections that control the clutch
mechanism. If you use a relay, you can get a good amount of current
to drive the unit, however how are you going to control it without the clutch control? How will the linear drive
know when to stop vs. the wheel pilot signals. Note that the linear drive is quite powerful. You need to make sure you don't destroy anything on your steering
quadrant. I saw a post somewhere that the linear unit when not installed properly, actually broke the tiller arm right in half! Imagine what it can do to your steering quadrant...Just my two cents.
