Do Go Devil and Beavertail frames vary by horsepower? My understanding from posts on this list is they do.

The reason I ask is I'm wanting to buy a GD or BT complete motor with the idea that I could use it with different engine, such as my almost 200lb Hatz 9hp diesel (don't ask - I bought it before I knew what it weighs, and it's a great big/little motor). But it sounds like I'd better get a frame that has or originally had a big engine on it. I'm assuming a mud motor with a 13hp engine will have a lighter frame than a mud motor that was made for a 23hp or 27hp engine.

Am I thinking right?

Thanks!
