Another instruction on engine and c-drive mounts and vetus coupling alignment

Raul Schleier

Thanks for your input Eric,

Based on the comments and other articles I read on this forum it is now clear to me there are many variations. Many people report different types and brands of engine mounts and I didn’t know you don’t have to cut the bolts on later models like you describe. I guess I wouldn’t have had to cut mine either had the coupling not been stuck. I cut them so that I could pull them out backwards and insert the rods to use as an improvised gear puller (or rather “pusher”). There was no way I could remove the bolts the way they were mounted on SeaBean with the flexible coupling being stuck. Glad the design has improved on later models.

I had planned to take my hub to a machine shop too had it not been for a long weekend so I figured I’d give it a go with emery cloth and it turned out to be enough. I’m pretty confident I will get it off quite easily next time having used tef-gel on the shaft.

All the comments just go to show that there are many variations and the only boat I know for sure the document is valid for is SeaBean.

Hello Raul,

That was an amazing job. I just have 2 comments. On later Amel’s such as mine #376 you do not have to cut the bolts to remove them from the coupling.

Of course, you must use threaded rod to replace them.

Secondly, I had a machine shop cut a few thousands of an inch out of the center of the disk brake hub. This makes for easier removal in the future , I also applied Never=Seez to the input shaft of the sail drive.

About 5 years ago I replaced the donuts in the coupling. Last Spring, I replaced the engine and the disk brake slid off very easily.

Again, Great Work !!!

Hi All,

I have just replaced my Engine and C-Drive mounts and the rubber doughnuts in the Vetus flexible coupling and then realigned. I had some local talent replace the engine mounts when we first bought the boat but he screwed up so I decided to tackle the project myself. After reading everything I could find on the subject, the project still scared me but in hindsight turned out not to be too difficult. I documented the process and saved it under the files section here if anyone is interested. This thread was very useful (among many others).

There’s nothing new in my instruction I just posted that hasn’t already been covered in this forum. Nothing in the process has been invented by me. I just took lots of pictures and tried to explain what I did and what I didn’t know or understand in case it can help someone doing this the first time. If you’ve already done it, this instruction is probably of no use to you. The instruction is based on our boat, SM2k#344 with a Yanmar 4JH3-TE and may not be valid for your boat. Use at your own risk and don’t sue me if it all turns to custard. Please let me know if you find any factual errors so that I can update the file.

Many thanks for your encouraging comments and feedback. As stated, I certainly didn’t invent anything, just followed a process that was already described in several posts by lots of people including Bill and Olivier and many others on this forum. This forum was actually one of the drivers that got me on the path of becoming an Amel owner in the first place, so if I am able to contribute in a very small way then so much the better.

Cheers

Hi Raul,

What an excellent publication - you have certainly set a new high standard.  Many thanks for your time and effort to compile this.

Raul,

I assume that you used the document I sent you as a guide. It was a compilation of procedures and photos from several Amel owners, and more than a few have used that document. Like many procedures, something will either be unclear or lacking unless an expert in writing procedures actually does the job and writes the procedure.

You are definitely that expert. Thanks from all of us.

Bill
