...Max asked if backing hard might have caused a high oil pressure condition. I said no, not likely.
You did get me thinking though. I wondered exactly what the engine looked like in an emergency backing situation. As we are now motoring across Buzzards Bay in flat calm conditions I decided to find out! Now my wife believes I am a little crazy bit she dutifully participated in the experiment that I recorded and then posted to YouTube. The video is of our Yanmar 3jh4e going from about 2400 rpm's and 7+knots to full reverse. You can hear a click/thunk as Dorsey selects reverse. Do you notice any unusual vibration? All seems pretty mundane to me from this view. Dorsey says it sounded much more dramatic from the cockpit.....
