I know CMB used to make boat engines back in the day ,but haven't really heard to much about them in the United States.
I have found another distributor of the CMB Engine
Ashford Hobbies
I found this information also under the engine page, it provides some added info.
Mr. Rich Reid hangs out here also maybe drop him a line
