So last year I had to replace the cone drive in my Kanzaki KM3A and really don't want to do this again prematurely. After reading comments I feel validated about my practice when I sail with the motor shut down. Now, what is collective advice on transmission setting when motor sailing? At times I find the wind is perfect for a sail (not talking about rails in the water sailing), but also have need to run my Yanmar 3GM to charge batteries after long time on hook. My current practice is to leave tranny in forward setting and reduce engine throttle to find sweet spot where prop shutter is minimized. Look forward to your opinions.
