They do not lend themselves well to retro fitting but a CPP (controlible pitch prop) would be by far the most efficient.

Also being shut down much of the time should reduce maint.

On a new build the cost is not excessive .

An EGT gauge is required to optimize performance.

One of my pet concepts for a world cruiser would be a single shaft CPP bolted to an LST style transmission.

These mount 2 engines , either or both can power the shaft.

To me twin engines is a fine idea , but 2 exposed shafts , much unfun.
