My Sabre 30 has a Westerbeke 20B Two engine and JS
The engine manual says the tranny should be left in neutral while sailing. But, the Sabre manual says it should be in reverse.
The Sabre manual says less drag when the prop is not moving and oriented vertically. No explanation of why in engine manual.
Is there harm in letting the prop free wheel?
I don't race, so not too concerned about the drag...unless it's significant.
