xvz12, a picture would be nice, but it's no hurry. I'm still unsure of what kind of "boat" I'll put it on, either a homemade flat bottom simple hull, or one of those knee boards that are used to pull behind real boats. I made one a few years back with a .35 glow engine on it, and it was waaay underpowered. Once I figure out which boat I'll use, I'll come up with a way to mount the engine.
Thanks for letting me know the adapter will fit. I just can't imagine finding a cheaper solution! Looks like I'll be placing an order for one soon.
