I'm running a standard length bravo 1 upper and lower 1.5 to 1. Will a speedmaster sport master -2" 1.5 to 1 with a 1 1/4" prop shaft fit. If the prop is 1 1/4" what is the input shaft size. What size is the input shaft on a bravo 1 lower. I've seen imco uses a plate on the upper to mount the drive shower pick up. What does speed master use.
Thanks Peter

The imput shaft is the same size on the Bravo 1 lower and the speed master lower. meaning they both bolt up to your upper. If you are not going to use a cavitation plate you could mount the shower pick up where you would normally mount the plate.
hope I answered your question
