sprint cat with mac 67

[Gordon Dawson]

What is a good heat race prop and strut angle to run on a sprint cat with mac 67?

I just bought one for my son to club race.

Gordon, Lay boat on flat surface and push strut all the way down. Angle should be parallel to bottom of boat. Start with an Octura X455 prop. Ray

I can't tell you about the Mac motor. I run an OPS 67 in a sprint cat. I have a Propworks specially made from Randy in Minnesota -- X457 really pitched up. Strut is pretty flat with centerline of the shaft at centerline of the sponson transoms. Runs all day long in the 50's.
