Re: [Amel Yacht Owners] Rough engine at idle

Hello Miles. Many of us eager to help you suspected you had a 46/48’ Amel Maramu because of your mention of a Perkins M60 and a cutlass bearing. Much of the advice you got was in reference to the later 53’ Super Maramu, much of which is not applicable to your Maramu...
I might gently suggest that all who post here always add the model, year and hull number below your sign off as well as your current exact/specific location.
Why? Knowing what model you have is very important. Sometimes in a given model year ,which runs from September to August the following year, there are not unsubstantial evolutions in standard equipment and configurations. The exact location can often give you the nearby contact information of someone who is Amel familiar who knows how to assist you with your challenge.
Always a good idea to give us all this information to get the best result.

Have fun with your Maramu! 
Joel

Hello fellow amelians
In the canaries our engine purred nicely
When we arrived in the Cape Verde’s it was a little rough on idle
On first running since the roughish Atlantic crossing (40-45kts during last 5 days) its even rougher still
I have a Perkins m65 with around 3k hours
It starts on the button but vibrates lots until the revs are increased.
Would be great to hear thoughts on any simple things I could try. I don’t think I can adjust the idle speed on the engine. Perhaps I could via the throttle cable but don’t want to make matters worse.
I’ve bled the fuel

I’m currently in Barbados where I can’t seem to find a diesel mechanic
Next stop Martinique where I’m sure I’ll find good professional
We ran the prop shaft alternator on the long crossing for 2 weeks straight. I started to notice that in the higher winds towards the end of the trip the noise from the rotating prop would change to a less regular sound at speed - almost a knocking sound
I think perhaps the prop shaft alignment needs adjusting. Perhaps the two issues are related although if so I’d imagine the vibrations to get worse with increased revs rather than get better

Any thoughts most appreciated and any pointers to good mechanics in Martinique would be great too

All the very best

Miles
