My CnC 36 has prop shaft offset to port and therefore under power boat will
steer to port unless rudder counteracts with starboard angle. When motoring my
wheel is proabably two inches off dead center to starboard to steer straight
course. The more rpms = more thrust = more port turn = more counteracting force
required. Having said that, no issue with autohelm 4000+ handling this.

I was on a long cruise last weekend and we ended up motoring for many hours.
installed a new Raymarine EV1/ST4000+ wheel pilot last winter and this was the
first extended use. I found that it was frequently cutting out while motoring
(not sailing). The unit would simply freeze up and stop steering while the
boat drifted slowly off course. No error on the P70 controller screen until I
got an off course warning. I also noticed the wheel pilot getting warm/hot
when this was happening which may be why it cut out.
I also notice that while motoring, there is significant pull on the wheel that
has to be fought to keep the boat going straight. Is that normal? I am
guessing that the wheel pilot is overheating due to the power needed to
continuously fight that pull? Thanks- Dave
