No first hand knowledge but it looks interesting.
I read the linked info, also the linear drive
version. It too looks interesting. Can it be used on deck
But, my Raymarine
ST4000GP drive unit is over 9 years old and works fine. It's now connected to a Raymarine
X5 Smart Pilot. It's been out there on the aft deck
so long the anodizing has turned to a bronze
color. I have a new spare drive unit, don't know how long I've had it.
But we've been using this type of Raymarine st4000GP drive (Autohelm) for 23 years. We've replaced the drive unit maybe three times (once when I walked on it and broke it in half). A few times we've broken the thrust cap or the tiller drive pin, but fixed them every time.
Of course, if you rarely motor
and never use the autopilot
unless motoring, they last a long time.
So, I guess what I am saying is, "Do we need a new kind of unit?"
