I keep getting conflicting advice and am hoping to find some consensus here. When under sail and the engine shut off, should you put your transmission in gear to avoid the prop spinning or should you leave it in neutral? If in gear, should it be forward or reverse? I've been told both. Last comment was to engage in forward gear to avoid burning out transmission cones. I don't have a shaft brake and don't really care to install one since it's a pain to get to my shaft and I don't want to have to do it every time. I have a Beneteau 321 with a 27 HP Yanmar.

sail in reverse
yes, the consensus was also based on technical advice from the Yanmar people, their reason was that in neutral or forward the tranny and even engine may turn, but without the oil pressure or speed to properly lubricate. In reverse the gears are stopped against a proper mechanical rest.

Except when....
One has a feathered prop, in which the advice is to go from neutral to reverse for 30 seconds, then back to neutral. To check if it's stopped spinning, go aft below and listen. If the prop is grinding, then no back twirl.

Reverse
Reverse has been the consensus next time put in neutral and go below and look at the shaft spinning and humming you'll run up above to get in in reverse! t.

It Depends upon the transmission
There was a long debate and it seemed to depend. My handbook for my Pearson 323 with the Walter V drive and volvo MD11C engine recommends putting it into reverse. Check your manual!!

Autoprop is the only Prop I have heard you
should put the tranny in forward gear when sailing. The reason being is the orientation of the Autoprop self pitching swinging blades will articulate backwards under sail and when the gearbox is in reverse it might actually turn the shaft. This is the only prop I have heard you do this for. Bottom line is you don't want the shaft spinning while in gear.

just to add to the confusion
I have an e-mail answer to this question from David Swain at YanmarHelp.com. I have a 2GM20F and he said ideally neutral, never forward.

He needs to explain
So far there isn't much confusion, rather a fairly good consensus with the prior discussion. David needs to offer some logic or at least reason why he differs from previous Yanmar wisdom. He agrees with forward (not using it), but perhaps thinks neutral is the logical alternative. Or perhaps he's speaking for the engine without assuming which tranny and how best to apply the brakes.

Geographic accuracy
We’d all be wise to ensure that any advice is Geographically Correct as well as “Politically Correct”, “Gender Sensitive”, etc). ie: The www.yanmarhelp.com site was first launched in July 2001 by Dick Tucker (David Swain’s predecessor), ex Service Manager for the New Zealand Yanmar distributor. Being from the Southern Hemisphere, where Reverse IS Forward (due to Coriolis effect), he (Dick who trained David), who might be called “it” (to remain “G.S.”) cautions against gearbox in forward (which is reverse to we in the “real” Northern world) - but, I believe that he/it (Dick ...), has already accounted for the fact that no-one cares about conditions on the “bottom” of the globe; so has already reversed the axiom to be understood correctly by we Northerners. Hence his/it’s axiom, “never in forward”, may be understood to really mean “never in Reverse - which is forward ... except in the Southern Hemisphere. I hope everyone is perfectly clear on this.

GordGord is right
unless Dick is left handed (so to speak). That may be right in the Southern Hemisphere but partly precluding painfully pinpointing planetary positioned, pointed, politically proper pronoun propriety proves positively paramount path - perhaps? - possibly? - Precisely providing propeller pitch produces properly positioned powerful port propulsion - probably plus prudently paying points.

My head hurts, I'm going to sail down to
Oceanside (in North American reverse) for dinner and rethink this whole Coriolis thing.

According to Yanmar
When I took my Diesel class at Yanmar, they said it really depended on if your transmission would lubricate without the engine running. Their advise was to put the engine in reverse. Since a forward motion can still allow the propeller to spin in forward.

WHAT are you doing???,,,coming up with the correct answer at this point and stopping the show when it was going great? Gords always right too and Patrick, I was going to report back on the Buddha search but,,,. We hiked the trail and looked all around the woods and rocks with no luck. When we got to the lake, the trail became very rugged. With my bad leg, we only went a sort way along the lake bank. We even brought our trusty digital camera to post a picture here but, alas, no luck. We did cross paths with the neatest black bear. Pould-pou-provide-petter-pirections-por-pur-pext-prip?

The Buddha is at the other end of the bay
from the creek and lake end - in the first little cove up maybe 50 feet to the right side as you enter. I cannot remember the actual direction but I think it was on the northeast side of the cove.

The Buddha
might have the answer to the original question. You must go back and get it. We will be waiting for your reply. Remember - it is not just the answer, it is the journey which is most important, Grasshopper. It is in Tsehum where you will see-um. Get it? Tenidos? I cannot guess what that means. Maybe "to need o's". We must all meditate on that.
