The Perkins M50 has run 4300 hours. It start still good on the first click, but creates some oil smoke and he oil consumption is at about 1 liter per 100 hours.
A complete rebuilt would cost about 50% of an brand new engine. Could be an option, but if you one day decide to sell the boat this would not benefit the selling price.

Yanmar still offers non-common rail motors up to at least 160 HP.  Actually they offer both versions for each HP range.  It’s your choice.   And they are great motors in my opinion😎

I agree you should avoid common rail diesels if possible however 50 Horses engines are still mostly classic injection. Volvo D2-55 could be an option. This is a re-badged Perkins that gives you a little extra power. Volvo can give nice rebates on re-powering if you push them a bit (I have experience).  These 4 cylinders run very nicely. Also have a look at Beta and Nanni. Nanni being French may have have specific experience with Amel. Keep an eye on the weight of the engine the older designs tend to be quite heavy.
Also look carefully at the design of the engine from maintenance point of view. Some engines have impellers and oil filters in places very hard to reach for some boats. For example; my engine is a D110i-C. This model was designed by someone clueless about converting engines for marine use. VP must have fired him as the later models D-H models) were very much different.
So for your Sharki look beyond the initial purchase price. Part prices, availability of parts and effort to maintain are also things to consider.

Hi gang,

If I remember correctly, Quelzal has a very nice installation...

A platform was added on the port side of the stern with a deployable telescopic ladder.  The deployable portion rests on the back bumper to prevent the ladder moving under the stern whe loaded with a humanoid...

Last year when I was in New Caledonia Marina I was alongside an SM that had fitted a very good fold down ladder to the stern, (not attached to the bumper) I will try and find my photos of it.

Ah thanks pictures I saw I thought it was fiberglass or fiberglass encapsulated wood.   Oh well it was an idea

James,

Assuming you have the OEM Amel bumper, the bumper would likely just rip off the back of the boat if you tried that.  It's made from some sort of foam rubber and held in place by just two M8 bolts with some fender washers. The bolts are meant to hold up the weight of the bumper and keep it in place in a compression load (bumping into a dock, etc.).  They are not meant to hold the weight of a ladder and person pulling down on the bumper.

I am planning to replace the original Perkins M50 on my 1989 built Sharki. Is there any advice from the community which are good replacement options and what are potential issues which I have to take care when installing a new engine.
Thank you,

Actually the capacitor may also help in reducing the sparking of the brushes and reduce the wear and tear on those things. So definitely recommend to replace. I can't tell you the value though as our Amel  is too far away to see.
