Question About Length

Postby digginfool » Fri Sep 02, 2016 4:31 pm

I've got a 68" Q that I'm not using. What's the difference between a 68" and 72" prop; the hub? If so, which hub would I need to make it 72"?

you add 2" to diameter for each hub size. (70-72-74 on Q or signature series)

I believe the 68" is a cut down size, I believe did some H's and maybe cuts in the short cut down size or maybe done later in blades life. I think 70" is normally the shorts want to say the blades measure something like 35" each. your short prop gives it quicker snap up or for a engine lacking the hp or even cage restrictions where a Longer prop snaps up slower but has more push for running ground etc etc it really depends on what type of riding you do on how you want the prop.

if you where around here I say stop by and we'll go to the lake and try all three hubs ...lol

I had a 3 blade 72" Q on my last boat. Don at Sensenich swapped a 2" larger extended hub for mine and I picked up a lot more push.
I like low cruise rpm .... less gas, less sound, so it worked great for me.
