I have an Autohelm
pilot and the actual wheel
drive portion of it is giving me problems. Can I just replace it with a newer version - like from a Raymarine
ST4000, an SPX 5 or even the brand new EV100 and still keep my control head
It seems to me that all that the wheel drive unit is is a motor
attached to the wheel with a two-wire power cable that reverses polarity to reverse the motor
. It doesn't look like the basics of that unit has really changed in 25 or 30 years (it's just gotten more sturdy).
I'd appreciate your thoughts...
