Attempted building a 1/8 scale hydroplane in the early 2000’s and unfortunately due to finances had to sell before finishing the boat. Saw this for a good price the other day and decided why not. There isn’t much info online about this CMB 67. Who can share what they know? Year, model, output power. Recommended tips to tune or make more power. Are there spare parts available? How does it compare to the green gold or blue heads? How many ports. Are parts available to do a remote needle? Any helpful info or documentation.
