There rated up to 6000 RPM's, but I would try and prop it to 5500-5600 WOT with a moderate load. It uses small carbs that will run out of steam pretty early on. Same engine as a 140 with a differrent exhaust tuner and carbs.

Prop
What size prop do you think I should use..... Do you think the step lift will have a problem getting on plane with the 120

The 120 will have NO problems plaining out a V-20 if propped correctly. I would say a 15 pitch stainless prop in a 13 1/2" diameter would do the job nicely for a starter, but you may end up having it repitched to a 16(I think the 17 would make it struggle to plane though).

Keep...if you need a prop I think I have a 15 and a 17 lying around in Alum. Would be willing to lend them to you for testing.
