Sounds like you had a lovely sail, Daniel.   I enjoyed that morning sailing with you.

If left in gear (something Yanmar recommends against) the transmission would lock-up with even the slightest forward motion such that the safety interlock would prevent starting the engine.     As far as I can tell the two blade prop does not spin in neutral and typically parks vertically behind the keel. Also, I did not notice any significant advantages with the three blade prop so I gave mine away and have never considered going back.     Currently sailing on Lake Pontchartrain, winds 15 gusting to 19 knots, double reefed main and 110% jib. Daniel SwordsSolitude, Hull #525Mandeville, Louisiana
