    Just out of interest, what is the preference for position of shifter when under sail? I've heard arguments for forward, neutral and reverse.

    There are a huge number of threads here which address that. It's not a matter of preference or opinion. The transmission manufacturers all clearly state what you should do. What transmission do you have?

    The only correct answer to this, other than leaving it in neutral, comes from the gear's manufacturer. For example, Hirth specifies reverse, and I think says you can damage the gear by leaving it in forward. JS specifies forward, and says you can damage it leaving it in reverse.

    It may be different for the different engines and transmissions. Always review your action in light of the recommendations of your product manufacturer.

    It is recommended the transmission be left in NEUTRAL position while sailing.
    Leaving the transmission in NEUTRAL while sailing alleviates unnecessary drag on the vessel because the propeller is able to freewheel (spin).
    However, to stop the propeller shaft from rotating while under sail, place the transmission in REVERSE.

    The manual for my Westerbeke 38B with JS gear says this:
    Sailing Operation

    The JS transmission should be left in NEUTRAL while sailing. Leaving the transmission in NEUTRAL while sailing alleviates unnecessary drag on the vessel because the propeller is able to freewheel (spin). However, to lock the propeller shaft and to prevent it from rotating, place the transmission into FORWARD gear.

    First, their assertion that allowing the prop to spin produces less drag is debatable; but in my case, with a Max-Prop, I will using neutral gear when sailing, after making sure the prop is feathered.

    If you have a folding prop it probably doesn't matter

    Universal / Hurth says neutral or reverse. Reverse is quieter but more drag.

    The documentation on my Borg Warner transmission from 1973 says "Do what ever pleases you.. "
    The transmission is oil cooled so the prop when sailing can be in or out of gear.​
