You’ll find references to this all over the web, but I was not able to find it on the Yanmar web site. Advisory Number: MSA08-003: DATE February 8, 2008 Dealers and OEMs TO: All Marine Distributors SUBJECT: Gear in Neutral While Sailing All MODELS: All Sailboat Engines We continue to get questions regarding the correct gear position while sailing with the engine OFF. This advisory is issued as a reminder; Yanmar requires that if sailing with the engine OFF (not running) the transmission shifter must be in the neutral position or internal damage to the gear or sail-drive will result. This damage will not be covered by Yanmar’s Limited Warranty. Please instruct customers and dealers who deliver the sailboat to the customer, of the correct (Neutral) position for the marine gear while sailing. If the customer desires that the propeller shaft not spin while sailing, either a folding propeller, shaft break, or other suitable device may be used. However, Yanmar accepts no responsibility for the selection, installation, or operation of such devices. Please also refer to Marine service advisory “MSA07-001_Yanmar Sail Drive Propeller Selection” for additional information. If you have any questions regarding this advisory please contact a Customer Support representative.

The idea is that preferably when the boat is on the hard, you set the prop so that the blades fold properly (horizontally), then you go up and mark a line on the shaft and a non moving part. Once underway and with the boat moving through the water you shut the engine off with it out of gear. Someone goes down below and rotates the shaft until the line you marked on the shaft is aligned with the other line you marked on the non moving part, which ensures the prop is set horizontally. The movement of the boat through the water folds the blades the way you want them. Then you place the gear lever in reverse, which locks the shaft in position. I have been doing this all season with great success. In fact on the 4 races you have been with us I have been doing this and you never said anything about it. You probably didn't notice I was doing that. You can tell the shaft never rotates because the lines always remain together. I don't see how the shaft is rotating.
