Cleaver style wheels for xr shaft?

[JasonSmith]

Where would I start looking for some cleavers to try on? Don't care much about anything other than going faster.:mrgreen:

[BrettM]

Get in line JS!!!

I have the adaptors ready, we just need some soft water and a set of 17"x 34 some one wants to let me borrow!:mrgreen:

You may need to get out the sawzall and cut out the
area above the cav. plate, cuz I don't think it will
be able to swing a 17" diameter prop without some
clearance problems;)

He is talking about the 17's for the NXT drive.

Try Hydromotive Props out of Cleveland. They have a program where you can swap out props for a $25 re-stock fee until you get the right one. They have a cleaver style as well..

[Hell Ya!]

I didn't know Hydromotive made a clever style?

[Griff]

They don't really, just the the Q4, P5, and H6 which really are not cleavers.

[JasonSmith]

I have some P5X's already. I want a true cleaver, like the #6 spins, but in a smaller diameter.
Julie at Throttle up said she could make some, but I ain't gonna let her tune my trolling motor propeller.

What size P5X's do you have ?

I've been sniffing around for some 30's,
to use when our good friend heat and
humidity come out to play.

I got some 26s or 27s, whatever Hydromotive calls them.
They are going to be too small for my boat, but I thought they were too cheap to pass on. That & I'm thinking of spinning my motors up to 6000 rpm for fun & to see if there is any more speed up there.

And then some. [smilie=appl] [smilie=appl] 6500 is a good number for hyd rollers and 200# of valve spring pressure. Try it you'll like it. Just don't leave them up there forever. Like running to Big Dicks or something.:mrgreen:

I was talking about the NXT's. I could have been a little off though. I thought Lucky 7's spun 17X34's or a set of 17x35's.

LOL! I kinda forgot about that run.:oops:
I've never burned thru 120 gallons of fuel in a morning before that run.:mrgreen:
I guess that extra 1500 rpm getting to 6500 will help that fuel consumption number out.:twisted:

[bbladesprops]

Hydromotive does not make true cleaver propellers.

I don't believe Lucky 7's ever spun anything that big.

True cleaver propelllers can be spun on NXT drives in the older Long Hub specification or any of the new CNC'd versions.

We can also convert Maximus or P5 propellers to cleaver geometry.

If you have any other specific questions, please let us know.

Hmmmm, a cleaver would be faster than a round ear propeller, but wouldn't provide alot of bow lift, right?
I think I understand the diffs, but could you give a quick "rule of thumb" lession?

[bbladesprops]

Cleaver propellers were designed to run on the surface. In order to have a surface piercing propeller operate officially, the boats hull, weight and balance must allow for this. What I mean is the boat must be fast to begin with and capable of speed without bow lifting help. putting a round eared propeller on this style set up could create drag slowing down the boat. Or even worse, certain round ear propellers will blow out near the surface completely eliminating thrust.

Boat requiring additional bow lift can expect better top end performance via the rounded cupped blades from these style props. In order to create bow lift you must leverage the transom. Think of a toy boat in a tub. Push down on the rear of the boat and what happens? The bow comes up. This is the only way to make bow lift other than natural Hydrodynamics of hull designs. Preventing the water from leaving the blades too quickly, allows the trim button to create more bow leverage. Of course as speed increases, the natural ability to pack air under the hull helps all boats go faster until the limits of the set up are matched. Then it gets hairy.

Because of todays high "X" dimensions, new higher rake angle cleaver propellers have been designed. The reasoning is to act as a rounded ear propeller. If we can't keep the water on the blade, we can't create thrust. Higher rake angles do create more drag also decreasing speed. However, if we need more rake to decrease slip, it is the lesser of two evils and we must use it.

I often wonder when the "Raise the "X" dimension mentality will cease.

[JasonSmith]

So, just thinking here & I do take your advice VERY seriously. My boat really doesn't take much trim to get speed. About 1/3 of the available trim limit is where I typically see my best speed.
Would you think that I could use a cleaver style propeller? I have to think that my setup has to be gettin gthe propeller pretty close to the surface.
Not that it really matters, you have me running fast enough now, I'd just like to experiment so I can learn.
Thanks!
