Prop thoughts
 

I recently purchased a 1988 Pachanga 22 with a 330 HP 454 and an Alpha drive. It currently has a 19P Mirage prop on it, and I know that is not enough prop. I think I need to be in the 23P-24P range. I'm looking for anyone that owns or has owned one of these boats and what prop worked best for them. Also, suggestions from anyone with some thoughts on this matter are welcome. Trying to gather as much info as possible so when it comes time to start testing, I'll have a good idea where to start.

How many RPMs are you turning with the 19P?

Had a buddy with a 22 Pachanga with a 415HP 454 and it ran good with a 21P 4 blade.

With the 19P I turned around 4700-4800 at WOT. This was good for about 57 mph. I know there's more speed in there somewhere.

Be warned: That alpha is seriously border line with that engine. Merc did it for one year and learned their lesson very quickly.

Yeah, I'm not real excited about having that Alpha behind a BB. Replaced the engine this year, and hopefully next fall I can replace the Alpha with a Bravo. Whenever I do that, I'll probably get to go through the whole prop testing ordeal all over again.

On a 454 with a bravo I had real good luck with a 22 Hydromotive Quad -IV

I'm going to take your advice from yesterday and contact Julie at throttle-up and talk to her, see what they can do for me. Thanks for the info. Trying to gather as many opinions as posssible. Can never have too much info.

Thanks again.

Ditto:

Hydromotive QIV is the ticket for your boat!

21 PITCH ACCLERATOR
 

The 21 pitch Mirage conversion to ACCLERATOR WILL deliver a great hole shot ,great midrange accleration that will set you back and gain 3 to 4 mph on top end on this application.here is a picture of the ACCLERATOR.

let me know and we will let you try one out.

I have a quad -I-V that you can try out.its not labbed but that we can do, if needed.

Although I never owned a 22 Pachanga, I boated with two guys for several years that owned them. Both had 454/330's but one had Bravo and one Alpha. They were 3-4 years apart in manufacture. The Alpha was just a little faster on top end. It also broke twice while we boated over the course of 5-6 years.

My experience is that you can't really afford to hook up the Alpha as well as is possible with today's props because of the lack of drive strength. That is, although there are plenty of props that can potentially improve performance, the Alpha just can't safely use the extra bite. There's probably a good prop guy that can improve top end, but low end might suffer.

By the way, the Alpha would run 60 mph easy.

Good luck. Those are really nice boats.

Had a P22 with a 383 SBC and 350hp. Best overall prop was 21 Mirage, boat topped out at 62mph GPS @ 4900 rpm. Best topspeed though on that boat (and thats the experience of at least 3 other P22s) is with the original 21 Cleaver...but nowadays not the way to go (poor acceleration and blow out in turns)
I would try Darins accelerator, cant go wrong there...Just my 2 cents..
Great boat, have fun...BTW never had issues with my Alpha, but that was SBC torque....

YOUR PROP WILL BE SHIPPED ON Monday,Thanks very much over there in Germany!:D

I had serious problems keeping a Mirage hooked up with a 454 and Bravo. The Q-IV hooked up nicely and never blew out for me all summer long. Might be lots of props that would work, but you would have to prove them to me right now.
I had such good luck with the Q-IV.
Repowering this winter and will be trying a 27 Q-IV to start with and working from there.

Hard to go a way from something that has worked. Most Pachangas with a Bravo have a higher than normal X-dimension and need a prop that lifts the stern not the bow.

Which is why the Q-IV works well with it. May have Julie try a few tricks once I get the right pitch dialed in this spring. Can not say enough about the service I have received from Throttle-up. Even if I just called with questions Julie spent as much time with me as was needed to find out what would work best with my boat. She called Hydromotive to find out what would work and was awesome to deal with!

My neighbors been running a 21p Spinelli cleaver on his '87 P22 / Alpha for 10 years. 68 MPH on any day, 71 on a good day. Stock 330 - 454.

Anyone have any thoughts on a Bravo1 4 balde 15 1/8 x 24? It's been labbed, but would it be too much wheel for my application. I found one locally for $250.00 which seems to me to be a pretty good deal.

I run that 24 Bravo on my 23' SeaRay with 385hp 454. I like it much better than the 3 blade 23 picth Mirage that it replaced. It planes quicker and planes at a slower speed, and handles good in the corners. The rpms with the Mirage were too high.

Now the only problem is, I think that this 24 pitch 4 blade is just a little too much pitch for me. My WOT rpms are around 4750 right now. I am thinking about having a little pitch taken out of it.
