[Amel Yacht Owners] Repower

Danny and Yvonne SIMMS

Hi Steve, I enquired of Amel about repowering from the 80 hp to 110 and was told that the 110 required a different C drive and if the larger motor was used with the same C drive failure would result. Why don't you ask Amel yourself.
Hope this helps.

We are considering a re-power on our 1992 Perkins Prima 80hp equipped SM. I would prefer the 110hp Yanmar, but have seen on some post, the C drive on the older drives may not be built for the extra horsepower. Any truth to this, or are all SM C drives created equal?  Also, any opinions on whether the extra horsepower is all that beneficial with this boat. What special considerations do I need when ordering the new Yanmar? For example, gearbox type and ratio. 

Thanks in advance for you help, as I'm trying to make a decision in the next couple of days.

Thanks for the info. We have decided to go with the Yanmar 80hp, and not risk any Cdrive issues. I feel that 80hp is adequate, and I like the concept of less fuel consumption as well.  Hopefully, we will have the details sorted, and the engine ordered tomorrow, as we are missing some nice sailing time.
