I have repowered my Kettenburg 32 with a Yanmar 3gm30. I pulled the old engine and founda that it had a stuck rings in one cylinder and it would soon be due for bearings. It's biggest problem is the cylinders are .005" out of round. It is on the border line between honing and boring. Everythingthing else works great. Newly rebuilt are the alternater, cyl head,& fuel injectors.
