Amel owners who did an engine replacement, please help!

We are replacing the old Volvo penta engine with the new Yanmar engine. we have problem - vibration. Did you have such a problem?

There are several threads on this forum on the topic.  Here is one with a description of the alignment process after changing out engine mounts:  https://amelyachtowners.groups.io/g/main/topic/29770137#42520

Both the original poster Alan Grayson and I used this process AND the alignment tool after changing our engine mounts and it worked well for us.

The simple answer is that either the soft coupling rubber donuts were not replaced, or the engine/transmission output - The Vetus Coupling and the C-Drive are not aligned correctly.

If you did not use a fixed coupling to align all of this, it was done wrong. Don't use it until all is aligned correctly.

Following the previous advise about proper alignment procedure and replacing the rubber "donuts" in the flexible coupling, I've had no vibration issues after repowering SM243 from a Volvo TMD23 to a Yanmar 4JH4HTE 110 HP.

Good luck with it and let us know how you make out.

Mark McGover, thanks you! This information is very useful! We are doing as Olivier wrote. Unfortunately, the link with files and pictures on Yahoo does not work. Could you send me the pictures? I would be very grateful to you

Mark McGovern
 

No problem.  All of the old Yahoo messages, files, and photos can still be found here on the new forum. You just have to use the "search" function. Search Messages, Files, and Photos separately using keywords like "engine alignment" and you will find a ton of great information.

Here is a link to the File folder with the information that I uploaded:  https://amelyachtowners.groups.io/g/main/files/Yanmar%204JH3-HTE%20Alignment%20Information

Last, it is customary on this forum to have a "signature" at the bottom of your post with your name, your boat's model and name, and your current location.  It not only makes the forum "friendlier" since we know who we are talking to but it also helps to know what specific boat you have and where you are in the world.   Another Amel owner might just be in the same port as you and willing to lend you a hand!  You can set up this signature to happen automatically whenever you post in your Profile.

Good luck with the alignment!

Does anybody know the thread size in the center of the top gearbox input shaft of the C drive on a super maramu 2000?
The thread has damage and needs to be tapped again so we can press the coupling back on to the 35mm shaft.

Are you talking about the thread shown in the picture below?



I am not 100% sure because the print is really small, but it looks like it is 55mm x 3.5 Thread Pitch from this diagram:



To be 100% sure have a mechanic measure it for you.  You can also email Maude at Amel.  She should be able to get you an answer.
