Hello gchabs, I too have a
Morgan OI 41. As a side note, my
Morgan is a 1973 413
ketch that wieghs ca 26,000 lbs. empty. I was surprised at your 29,000 lb weight. What's your year and model? I also have
hydraulic steering and I'm using the original Benmar drive
autopilot that I combined with a Nexus control
head around 1990. My system does me well, but today's technology would allow me to
pump the hydraulic fluid at the same rate with fewer amps than my
current 1/4hpDC
motor. I don't imagine that I'll update my 37 year old drive unit as long as it keeps working so well, but I will be interested in following the results of your inquiry. Take care and joy, Aythya crew
