Cleaver Prop ?

I had salesman at a boat shop want to sell me a cleaver prop....
Since I know nothing about props I thought I would go to the experts and find out if this prop would work on my boat or not.. I have a 87 Pachanga 22 with a 454 motor.

cleavers

The prop will work on your boat but it wouldnt be my first choice. those are surface piercing and are made to run with a high x dimension. I would try a mirage plus or a tempest plus before a cleaver. i have tryed cleavers and there is zero bow lift with them......my two cents

That looks like an old TRS cleaver. They were the latest technology in about 1978. I had them on an old Scarab. It may work well, but try it first before paying. They aren't worth much.

Old technology. Work best on light boats with high X.

"Light boat" must be the key phrase here :).

If you want to increase you cruise speed at the same rpm , try a BravoI. About 22". It may or may not effect top end speed , but you should see a few mph gain at 3000 rpms

Thank you for your input...
After some research and everyone's input I have found a 3 blade mirage plus 21 pitch. The more I tried to find the perfect prop the more complicated it became...

Bow lifting props
Stern lifting props
Pitch
Cupping
Out drive Props
Outboard props

It is all relative to what your boat responds to.

You will never know till you try it.

A Bravo 1 prop has more bow lift that a Hydromotive.

A Mirage has more bow lift than the Bravo 1

But the difference is minimal till you are in that last bit of tuning to get the most bang for the buck.

The cleaver is similar to the Hydromotive in the respect ...they really do not perform till you are spinning them to almost top RPM. They sux for mid range performance.

The Bravo 1 is a GREAT mid range RPM cruising prop.

Good speeds for mid range RPM turned (Like MOPOWER stated 3000 RPM is great)

I run a Hydromotive around 4000-4500RPM @ 70 almost everywhere I go.(max 5600RPM) Some in rougher water almost NEVER get to run in those ranges due to water conditions.

It is a choice that you have to make depending on what kind of driving you do.

Like tires on your car.
Do you really need the Z rated 35 profile on your Toyota Camry?

Or is it needed on your Porsche?

Thanks a ton for your input..

Is a $100.00 for a cleaver cheep?
They look cool..... But if they are old school Then I think I'll stay away.

I think I'll stay with a proven prop, like the mirage.

I have found several props that are for a alpha 1... but I have a bravo 1... Will the prop still fit my out drive shaft? I can't seem to find any information on this.

Thank you

ask the seller if you can try it B-4 buying. hey... seller could go along for the ride IMHO.

If it works for you it is worth $100.

Nothing wrong with "old school" when it is $500 for "new school" and 1 MPH

If it does not work it is worth $10 for a door stop.

I figured I would just add this to this thread first. I was given a 3 blade cleaver to try on my boat. I need to know what thrust washer/nut setup to use??? Where to get it?? Anyone know?

Nstylx, This may help you out. http://www.mercstuff.com/page01.htm

What pitch are you going with?

I have all the stuff on the prop and a spare set in the boat. I'll get some more info when I get back on Mon for ya.

Even though the TRS cleavers are getting dated they are still the best prop for speed on light hulls with high X setups. They were thru Merc Racing and new are much better balanced, pitch accuracy along with much thinner blades than Mirage, Bravo and other Merc mass produced props.

I just received my labbed 23p TRS cleaver from Hydromotive and plan on testing it this weekend. Man those edges are finger slicing sharp and it looks beautiful. Before non labbed I was at 12.1% slip. After labbing we are hoping to get around 10% slip which means 3-4 extra mph.


:D

Thanks Ryan.... The prop I got is a 25 pitch. I think it will be too much prop, but we will see. I can spin the 23 mirage to the rev limiter. It needs cleaned up a little bit so it might work out in the long run. I will atleast give it a try!!!

I think there is more mph in my boat if I start playing with props. I only have two props. A 22 Hydro QIV and a 23 mirage that my brother picked up form some whole in the wall boat shop in Oklahoma. The mirage has "hammer" marks in it where they added cup!?!?!?

Good luck this weekend... Let us know how you make out!

Ryan, how did the cleaver work out. I have a similar 383 eng. build. Not getting the rpm I wanted. Turbo 23 5200. Put larger jets in 79-85 and picked up 200r's from 5k.
