Thanks to the old brochure, I have found the Checkmate I had when I was a kid. It was a 1971 MX-14. In the brochure it is rated for 100HP. I had an inline 150HP on it and it was a handfull to drive. If anyone has one of these in any condition I am interested in buying if they want to sell. I do prefer one in need of restoration. My goal is to restore it with an merc 85xs, and restore with a factory interior and silver metalflake. Who's got one they want to unload, I have cash in hand and will travel.
