I had the same thing happen a couple of years ago. I was sailing alone and a sheet from the jib got overboard as I was motoring back to my slip. A loud noise ensued and I came to a slow stop with the engine running. The sheet had rolled up the propeller shaft to the hull and in continuing, pulled the shaft free from the rubber coupler that connects the propeller shaft to the transmission. I wouldn't have thought that a single-cylinder Westerbeke gas engine could have been so powerful as to rip up an nine inch diameter, one inch thick rubber coupler without stopping. Not having access to a replacement, I eventually had to construct one out of a polyester-threaded tire tread. Creating the bolt holes was a challenge. It has worked just fine these past three years and I always mind the sheets now. Steve C'est La Vie C&C 27

Engine alarm and then shut off. Apaprently engine restarted ok but no more fwsd or reverse. Then the line that had fallen over the side was noticed with one end attached to boat and other wrapped firmly around shaft. Shaft seems pulled back approx. one inch. Transmission seems to be spinning but not shaft. Hope to find out today if simple fix or a time consuming expensive one. Was a lot of pressure on boat end of line so worried also about shaft and strut. Hauling boat to repair. 3GM30 Mike Persistence Frers 33 From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Bill via CnC-List Sent: Monday, September 08, 2014 10:17 AM To: jonbooc...@gmail.com<mailto:jonbooc...@gmail.com> Cc: cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com> Subject: Re: Stus-List Yanmar 4JH-TE Repower on C&C 44 Jon, This might sound to easy, but could you have wrapped something around the prop shaft? I had a similar sounding experience when a piece of heavy line wrapped around the shaft. Had to clear it with a dive knife (took about 2 hours, working with a flashlight) then restarted the engine and all was fine. I was bringing the boat up from Florida, and it happened in southern N.C., so I ran it for many hours after without any issues. Bill MYSTY In a message dated 9/8/2014 9:11:08 A.M.

Eastern Daylight Time, cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com> writes: The Yanmar 4JH-TE on our C&C 44 went bang on the weekend. It was the last thing on the boat that hadn't been replaced so in some ways it is a relief to replace it. It is unclear whether we will go new or remanufactured at this point. I have been appalled in the past at Canadian pricing on Yanmar parts and I suspect complete engines would be the same. Nonetheless I will probably get a quote from a Canadian dealer. Who in the US would be recommended to get a quote from? We were happy with Bay Shore Marine on our way through Annapolis, does anyone have experience buying a complete engine from them? Is there compatibility with engine mounts , exhaust etc between the various Yanmar models? (4JH, 4JH2, 4JH3, 4JH4, 4JH5) If so this could open up the number of potential replacements. For remanufactured Schooner Bay Imports (Al Holzer) in WI seems to be highly recommended. Our current model is 56 hp but I think anything above 46 hp would be sufficient so the non turbocharged versions would work fine and of course the more recent non turbo versions have the same or higher horsepower. Any guidance on who to contact based on your experience would be appreciated.
