323 Repower

I bet this topic has been covered ad nauseum, but want to turn the MD 11c into an artificial reef and Repower. What is the easiest way to go? Beta engines have my interest. Is there one that is a direct replacement, mounting on existing mounts and mating up to the Walter v drive. Money is not an obstacle, it's why I work in my retirement. Just don't want to cobble up the boat.

Many opinions out there.  FYI, mine was repowered with a Westerbeke 30B three. Somehow the yard installed it without cutting the vertical support in the galley between the engine cover and the small door...

Removing the engine is also a great opportunity to refurbish, clean and repaint the engine compartment! And look at the wiring while the engine is out; it ia a lot easier to upgrade any electrics with the engine out, as some of the wiring id difficult to reach otherwise.

Whatever engine you install, do look at ways to make maintenance simpler; for example, positioning the oil filter in an accessible location; some engines may also need the oil sump drain plug relocated. Probably obvious stuff, but just in case!

Bill1188:
I see Beta engines are pretty much a replacement as they will configure mounts to those of the engine you are replacing. Also, the Walter V-Drive can be used. And horsepower for horsepower, a smaller package. May be a win-win.

Eddy:
Mine had been repowered by the original owner. He bought the Westerbeke direct replacement for the atomic 4. It's a marinized Kubota (Beta) v850 4 cylinder diesel. Mine has a hurth v drive. The divider between engine panel and cabinet door was cut. If pictures would help let me know and I can snap some next time I'm down.

The 3cyl Beta is a good HP match for the displacement of the 323.
Rule-of-thumb is one HP per every 500 lbs displacement.
I was not aware that they now had an option to match the Walter V-drive.
Six years ago, when I talked to a Beta rep at the Annapolis Sailboat show, this was not the case, and you had to use a Hurth V-drive.
