P5-X Props
 
Anyone want to buy the left hand?
I would buy the right hand.

Keith, you out there?

UNSANE 04-18-2007 01:12 PM

I might. I bought a regular P5 and the boat didn't like it. Julie and Matt are working with me to figure things out. They were a little surprised that my Fountain didn't like it. I already PM'd her about her thoughts on the 'X' version. Do we know if they're setup for XR drives?

t-islands 04-18-2007 01:21 PM

Pat, have you ever run a lefty on your boat?

No, I have not.
My boat runs perfectly flat with a right hand and just me in the boat. No port tab required until I have a passenger.
T, have you tried a LH?

I have a friend with a 29' Fountain I'm bugging too. He doesn't seem to want to spend the $$...
The props don't look like they have hubs installed.

No. I might just borrow one of my brothers this summer, just to see what happens.

Been away Pat, got your PM too - replying with #

Keith

Pat McPherson 04-19-2007 09:19 AM

It was great to talk to you Keith.
Bummer the props got sold.
I'll keep my eyes open for 25p or 26p.

krakmeup 04-19-2007 09:51 AM

Yep, same here - next time at the shop I'll ask what's around - someone's always changing up.....

Pat McPherson 06-04-2007 08:55 AM

Hey Guys,
I ran a box stock 25p RH on my boat yesterday.
2 guys, 40gal of fuel in conditions ranging from a 6" chop in the River to 2-3 footers in the Sound.
73mph top speed @ 5000rpm vs. 75mph @ 4800 with my 28p B1.
The boat handled vary well in the rough water. Better than with the 4 blade for sure.
I'm just not sure I want to spend the $600 for a prop that pushes my boat 2mph slower.
Opinions?

Hey Keith,
If you want it, it's yours. The prop came from a fellow OSOer that sold his boat.
I do think your were considering a lefty.
My boat ran flat with no tabs. With the 4 blade and two people I do run with a little port tab a lot of times.

Stormrider 06-04-2007 09:22 AM

pat, what was the diff at cruise speed?

Pat McPherson 06-04-2007 09:36 AM

The cruise speeds are vary similar. Maybe 100-150rpm more at 50mph with the 5 blade. Remember the 5 blade is a 25p and my 4 blade is around 27p though.
The 5 blade really shines in the rough. The boat does definately run more stable at high speed in the rough.

Not necessarily true.
Some of the guys that have run them on 30' Supers have reported the same or even faster top speeds vs. a 4 blade.

krakmeup 06-04-2007 09:50 AM

Pat, sent you PM. I'm considering Whipple options so I would have to re-prop, but I'm still interested. With my buddy's 26PX5 I saw increases across the entire range - + 5 mph mids, +3mph top end and more stability.

Stormrider 06-04-2007 10:38 AM

Mark, i would take losing 2 up top for 3-4 more at cruise.

Pat McPherson 06-04-2007 02:28 PM

The P5X does seem to be the best prop for your hull Keith.
I do know that on OH-Zone's boat the top speeds are about the same with a P5X vs. a B1 and cruise is better with the 5 blade as well.
On my 24' the P5X is only better for rough water handling. I will probably not spend the $$ on this prop as I do have other items on my boat requiring attention/$$ right now.

krakmeup 06-06-2007 09:34 AM

Thanks for all your help and input Pat. I'll keep looking for a PX5-25 LH until I make any other changes.

No problem Keith. Keep me in mind if you find a killer deal on a pair.
The timing is just a little off for me to buy this prop. I was ready to pull the trigger a month ago, but.
Just got other items on the boat to spend $$ on right now...:rolleyes:

krakmeup 06-06-2007 02:38 PM

I hear ya! Don't worry, if Ifind a smokin' deal on a pair you'll be second to know about it!

SUPER AIR 06-13-2007 12:48 PM

Any one use a prop like this - I got a 598ci - in a 1985 24' Superboat and was thinking of bidding on this propeller labbed 25 pitch 5 blade and double cupped.

That is an outboard prop.
I was told the High 5 does not have enough blade area to carry a heavy i/o boat.

SUPER AIR 06-14-2007 09:38 AM

Whats the diffrence, Mercury V6 ob props fit, bravo, alpha ect ?

I'm just relaying what BBlades told me.
"Not Enough Blade Area"

SUPER AIR 06-18-2007 01:20 PM

I talked to a few people - they said this will work on most V6 applications and outdrive Mercruiser, TRS and others which may need a hub chenge.

superboat1989 06-18-2007 02:25 PM

The high five is a small diameter prop in the 12 inch range . as compared to A Bravo one 15 inch range for same pitch.

You will be disapointed as there is not enough blade area to carry your weight boat IMO.

High fives are mostly for light weight outboard bass boat applications.

Pure Energy 06-18-2007 05:59 PM

I just tried the p5X, the speeds were the same and 1 mph less at top end. Boat felt a little sluggish compared to the 4 blade.

Anyone need a 28 LH P5X before I return it?
