you need to do both. but id call bob at ultra prop and ask him. he will probly tell you to change the blocks down low before you cut'em down. but im guessing 42" and some 14* blocks would give you quite a bit more rpm. is it a 3 blade?

oh. uh? well???? thats alot of drag on a 13. you may wanna get a reduction. thats the only way i see you turning that bigga blade. i was wanting to get a 4 blade 42" this week with smaller 16* blocks. but i got a new 20.8 honda im gonna direct drive. i dont suppose yours has a 1 1/8" hub? i mite be interested.
