Hi All,

Have seen question pop up a few times.   Does anyone know the "why"
involved in Yanmar's recommendation of neutral?
My thoughts, having had to disassemble and deglaze the cones on my Kanzaki
'box:
- If in neutral and the shaft is rotating you wear bearings, stuffing box,
shaft, but you do not transmit any load to the gearbox, clutch, crank.
mounts etc.
-If the shaft is not rotating you transmit some load via the drivetrain,
esp with a fixed prop..
- IF the gear is engaged AND the shaft is rotating, (whether forward or
reverse) you risk polishing/glazing the mating clutch surfaces, which are
touching but are not forced together by the thrust load (the opposite in
fact, in fwd).  This is indeed debilitating wear, and is well worth
avoiding.
I'm not an expert but the latter case is the only thing that makes sense to
me.
Thoughts?

Dave

It depends on your transmission and engine. Yanmar had a bulletin a while
back for their engines with Kanzaki transmissions stating that they should
always be in neutral when sailing. Damage or wear to the transmission would
occur otherwise.
Cheers,
Paul.
