The DF150 has an unusually low ratio gearbox, so don't compare it with your Yam 100 on a like for like basis.

IBWET on here has a DF150 on a Ribcraft 5.8 and he's been experimenting with different props, so should be able to help.

EDIT: I'm assuming your replacement motor is a DF150. If it's an older V6 2 stroke, then ignore all the above.
