If I decide to go with the same engine stand I will just go with a 66" q series with some extra pitch.

I may try the short hub to make my Q 70"and see how that works.It just seems that most of the post on here state that the Q may be a little too wide for the 4 cylinders.

Captin, I ran a 70" Q on my 4 banger for 2 years. All around great prop, I found the NGH to have a better mid range, quieter , and a better top end. IMO I would not go down to 66" because it is going to effect the cruise!

My brother had a 66q on 180 and it was very flat. I would not go below 68 if you can help it. Capt. Just let me know I can send you a 70"Ngh and you can use the short hub to test your 70q against the Ngh .

What do you mean by very flat? Are you talking pitch wise? I have a friend with an angle valve 290 with a 66 Q and he loves it.

Q props tend to fall off on the top end!

Darren at sensenich told me he thinks they have used a short hub that I can swap for my medium hub.I will be able to try the NGH and the Q to see which one works best at 70".When I do this I will post what I find.

I had a 200av with a 70'NGH on a 12x7 hancock sled (the yellow hull/orange rigging one up for sale recently)..the NGH was a great prop for that set up, you could run on a plane with a passenger at 1200rpm and have a conversation.. it would run up and down the hill np with two people, and as for top end the boat clocked out at 71 in skinny water on the gps...i had it pitched at 2..

Sen. mailed out the short hub Friday.As soon as I get it I will try the Q and see how it performs .When I pulled my medium hub off to swap out for the short hub i put my 68" Cypress on and did at test.Hole shot in deep water 60 yards 32 MPH.Cruse speed at 2000 Rpms deep water 23 MPH.WOT deep water 38MPH.Break free on dry ground 2200-2300.This was done little or no wind.93 degrees high sun no moisture on the ground.It will be interesting to see how the Q and NGH do.Engine is turning 2800 RPMS WOT.

I run a Q-68", on my O-360- 12' Scorpion. A lot of pitch. 2 1/2. Great push, cruise at 1600- 2 people, gas is around 4 1/2 gals a hour. Truthfully, I wouldn't want it any faster for topend, I'd have to call the control tower.

I run the 72" wt wide or regular blade on my 200av. I had a 72"Q and it performed well but the wt is better on my setup. If your 180 or 200 won't turn the 72" Q then your motor ain't very strong IMHO. I tried the cut down blade wt to make it a 70 " and wasn't impressed at all. Also tried the narrow blade w/t and wasnt impressed at all. It was snappy but went flat after about 2200 rpm and I tried many settings. The longer the better IMHO. 2 other buddies 1 has a runout 180 running 72"Q on 2 mark, runs great. Other buddy has a 190 av carbed motor, fresh rebuid, he has. 70"Q it doesnt do any better or as good as the 72"Q on the 180 boat.

I have a Lycoming Angle valve 200.I didn't say the engine couldn't turn the 72" Q but that it seemed to go flat in the upper RPMS.It had a lot of push down low on the ground,and cruised 1800-1900 RPMS in deep water.From what I have seen there are a lot of 0-540 260hp running the 72".Thought I woud try a 70" on my rig to see how it performs.And by doing this I can also try the NGH.By running the short hub it gives more options to try.If I don't like what I find I can always go back.I like the idea of being able to try different props to see which one works best on my rig.

A 72" is a little to large for a 180. I would stick with a 70" and put some pitch in it!

68-70" is the ideal prop size for a 4 cyl. That's from a lot of people in the business I've been talking to.
