Amel Repower or not

[Mango51]

I have a 1983 amel mango with a Perkins 4236.
10k hours which I don’t trust. I’m having health issues constantly that don’t go away. I’m going to have to sale the boat at some point a year or three from know. I have free dock and love working on her.
My choice of engine would be a Yanmar 80 C Rail. I know everybody hates computer controlled engines.
If you were in the market for the amel mango would avoid mine because of the 4jh80 common rail?

No. It wouldn't make me reconsider.
Some like them, some not...but I doubt many would reject a boat due to that specific feature.

Good luck, and enjoy working group on her.

If you are going to change to a different make/model of engine, you had best REALLY love working on her. All the hoses, cables, wiring, and engine mounts will be in the wrong places. The new engine may not even fit in the tiny space the designer allowed. If you really want to do it, one recent poster actually made a wooden mockup of his new engine so that he could figure it all out.

The most economical route would be to pull the engine and have it overhauled.

I have a 4.236 and am thus biased. I would not avoid your boat because of the CR Yanmar, but, all else equal, I'd prefer either the original engine with 10k hours (assuming not known sick), or, a fresh rebuild on the original Perkins. Logic being that, even if the Yanmar is a good engine and installation was done professionally, overall the installation is less proven in that specific boat. If you install the Yanmar and go flog it for a couple hundred hours this would change things.

The above said, some buyers are enamored by "new" and will pay a premium for the same.

Nice boat BTW.

I too would rather have the engine that Amel chose to install. It would give me piece of mind knowing what I was buying.

I’d probably prefer the Perkins too, but the Yanmar certainly wouldn’t scare me away from the boat. Shows you care a lot for the boat. A repower is one of the most “non cheapskate” things someone can do for a boat and shows they have not been shy about spending money to keep her in top shape.

Rebuild the perkins parts are cheap it is a sound engine and you will have another 10000 miles on her , there is a reason most late 8os boats and 90s onwards and aaildrives get new engines while your perkins keeps on giving yes I am a fan boy I love my perkins 39 years old and runs and starts since the day she was born

My question would be what would be the return on investment given your health and your boats age? Just something to ponder.

Having the engine removed and rebuilt at a factory or large shop specialized in rebuilding trucks engine would be the way to go, in my experience.
1- the Perkins you have is a very good engine and many versions of it are used in many indutrial applications(Genset, pumps, agriculture equipement, etc. ). This implies that parts and experience abound.
2- Industrial, large shop specialised in diesel engine repair and rebuilt have the right equipment and methods to make total overhall of engine for a good price. And fast!. They do that all the time and their process is well refined. They will dismantle the engine check all the parts for wear(as per manufacturer specs) and will clean everything install new gaskets and often provide better the OEM replacement(Gaskets, seals), as it ewas the case for my engine head. They offer a good waranty on their labor.
3 Small shop, single mechanic, are not equiped and can't provice such industrial approch to engine rebuit, and should be avoided for a total rebuilt.
Amazingly, in my experience, this industrial rebuilding of engine is in the end cheaper than a other ways of rebuilding engines, and much much cheaper than a new engine . The trucking business use this kind of service all the time and a shop specialized with truck engine rebuilt are the best... and the cheapest!
If you go trough a marina services, they often farm out the work and add a significant cost without any benefit to the customer.
Once the engine shipped, you will still have some work to do like refurbishing the enfine room, painting, cleaning etc... The fun!

A diesel engine in a boat like that, a true world cruiser, that depends on electricity to keep running after starting, the C-rail, makes little to no sense. I believe that any serious Amel purchaser would walk away from that engine, regardless of new or not. People who buy Amels are most likely to be knowledgeable folks who look for quality and simplicity of systems. C-rail is NOT simplicity.


If someone with a boat like mine, you know a Production boat for protected waters, folks would jump at a new engine, regardless of whether my Universal M25 was replaced with another Universal, a Beta or a Yanmar. If they knew anything at all, they wouldn't buy my boat with a C-rail replacement either.


Come to think of it, have you considered a Beta? Always hear good things about them.


Good luck.

No. But I also avoid one with a Perkins with 10K hours at probably a lower price as long as the engine surveys as good.

10,000 hours is not huge for a well maintained diesel engine. Have it pulled and rebuilt if it bothers you and let the next owner pay for the new engine ( most of the cost of a new motor you'll never recoup in the sale)

Sorry I didn’t reply to anyone I was at work. Thank you for all your opinions and thoughts.
