Re: Prop Not Turning -- C&C 27
Thanks for the replies. Here is some more detail from my boat partner, who is closer to this than I am.
I just bought a 1987 C&C 27.
It's my first inboard engine (Yanmar 1GM 10) and my first folding prop.
I had been having a tough time getting the prop to fold out, and was experiencing intermittent heavy vibration when, I assume, it wasn't folding out properly. I spend the last week or so, shifting back and forth from forward - to reverse, trying to get the thing to spin right.
Then the other day, I was out for a sail, and fired up the engine, and motored for about 20 minutes before I started seeing my knot meter fall to zero.
The engine ceased to provide thrust in forward or reverse.
I could see via the cockpit locker access that the prop shaft is turning a little.
So after sailing back to my mooring, I grabbed a GoPro and made this video youtube.com/watch?v=Pxl4-ZhUdvc
While filming the video, I had the Yanmar running around 1200 RPM. I shifted the engine from neutral into forward, then reverse, then forward again. The prop shaft doesn't seem to be spinning consistently or much at all.
The engine runs well, and the transmission is shifting, but something seems to be broken somewhere between the stuffing box and propshaft.
Thank you for your kind consideration - any advice would be helpful
