If? it is an original 1970 raceboat it would be fun to have. Combs built the race versions very light. They ran low to mid 50's with a 44 cubic inch 4 cylinder Mercury. They ran even better with the 55 hp OMC. They were faster than the first Allisons. Combs never tried putting a pad on this model. The first fire at Checkmate lost these molds. The next version of the 13 [MX13]was wider, heavier, had a pad and slower.
Jake ran T750 with a similar boat at Gravenhurst.
