All the Hummels I've seen are VW powered. They're almost all metal motor box mounts, but Dennis Brooks used a welded mount for his H5. Works great. Dennis has built and assisted building on a few UCs. I'd reach out and pick his brain. He's a super nice guy. Good you tube videos as wellHello Bigshu. I am building an Ultra cruiser. Power will be a Rotax 503 mounted plugs down, B box up, to match the thrust line. Do you know of anyone that has done this using this motor box ? Any Ideas ?
