I speak from experience with the Hurth/ZF non hydraulic gear box. The insructions that came with my new Volvo D2 75 on a helm station decal is to have the gear either in neutral (spinning freely) or reverse, never forward.HOWEVER, the purpose when in gear is to stop the prop rotating at all. The slow spin you are seeing will be wearing your plates. Put it in the gear that stops the prop dead. I have a wierd experience. Sometimes that is forward gear sometimes reverse. What I do is lift the engine compartment lid when I stop the motor and am sailing with the gear in neutral. Prop spinning merrily. I put it into gear. If there is a satisfying clunk and the prop stops dead. Thats the gear I leave it in. If it slows without the clunk I put it in the other. I have no idea why, but it has worked like that for years. I know the slow spin is damaging. There is no rhyme nor reason to this.
