first of all nice to hear from you and your positive experience.
Moving the engine was necessary to get rid of the nasty hydraulic
power connection to the prop. The pressure tube broke three times
during the first 12 years of my ownership and always in difficult situations.
When the connection breaks there is all of a sudden no stearing control.
That happened two times in the Northern to Baltic sea canal with a lot
of big ship traffic. Moreover you will find some liters of oil in the bilge too.
I bought a new Perkins Sabre 65 which fit perfectly underneath the companionway. Space is quite narrow around, but the modern engines are fortunately smaller. The new position is better for weight balance. More important is the much more direct power after switching the gear. It makes turning in small harbours much easier.
