Another person who had the same results as us. No top speed loss with a 5 blade.
He didn't see a top speed drop off because he was running the high altitude prop. You have to look at the data and try to get a fair as possible comparison. If he had been running the stock non HA prop his starting top end would have been in the low 40's, I would think, and then drop into the high 30's. With my 45 I dropped from 42 to 36 - 37 MPH with the 5 blade. Not good for my use.

Maybe the 45 and 25 are completed different animals but all I know is the 45 is a barge and takes alot of power to go fast.

He does talk about top speed. It's in his post. I'm also very familiar with the X45. I have one sitting next to my X25. The HA prop doesn't make that much difference over the normal stock props. I've had both along with the 5 blade. I have lots and lots of hours in X-Stars, X25's, X45's and now I'm logging hours in a new X30. But hey everyone can have their own opinions and their own real world experiences right. Shawn tested three or four props and I don't think there was a drastic difference in top speed between any of them. I know that 95% of people buying a MC are either surfing or wake boarding and not too many redline their boats just to cruise at 40+ mph for any long periods of time. I would venture to say most people in MC spend time going 24mph and slower. I know that even when we are cruising longer distances we still never go more than low 30's. Why burn the fuel. I've only checked the top speed less than a handful of times just to see what each prop would do.

From Shawn's Prop Test:

"Top speed on stock was 37.5, 5-blade 38.5, 1285 39.
I didn't see any difference in the shape of the wake but I didn't ride at all yet.
Yes the idle maneuvering with the 1285 was pretty much the same as stock."

So he gained on top end?

Had 2011 X-45 out tonight with 4 people, Ilmor 5.7 and 14.75 X 15.5 prop. Hit 40 MPH, I wasn't driving but holding GPS, may have been more room in the throttle, forgot to ask. I love this prop! Best all around prop to date. (Haven't tried 5 blade)

So the question which should be asked then (also) would be why someone is going to develop a 5 blade with knowing that it would be only for a very small marked? If you look at the ads you get the impression that you are looking at a evolution in boating, at least concerning our MC world where we are used having 3 or 4 blades (yes, back these days I run a 3 blade on my prostar 190).

Axis and malibu guys with big weight are running the 15x12. I don't think they make a version for mastercrafts right now. I wonder if it's in the works?

I have a buddy with that setup on a axis 34 mph top speed at 4500ft with 330 motor. I bought the OJ 5 blade and like it for surfing a lot works awesome when boat is fully loaded wakeboarding bottom end is better runs 100 Rpm higher at 25 mph at 39 mph GPS checked runs at 5200 Rpms with a 4 blade never broke 5000 ever I save fuel how much hard to say I know that mcx in my xstar works a lot less harder at low speeds so I think that's the best thing about the 5 blade prop

Pulled this from the web sight:


"TZ-X5
Need more than one reason to know who the leader is? We have FIVE reasons OJ continues to lead the pack in inboard propeller development, introducing OJ’s latest innovation, TZ X-5, the first wake boat specific 5-Blade inboard propeller.
Building on the success of the large diameter XMP EDGE propellers, we teamed up with Travis Moye and Zane Schwenk to develop this revolutionary 5-Blade propeller. Travis, a world class driver and boarding instructor, and Zane, one of the best all around skiers and boarders in the world, provided crucial insight and expertise in the development of the new 5-Blade, hence the aptly named TZ X-5 was born.
The TZ X-5 provides unrivalled low end power and consistent RPM under the most extreme loads. Want to sack out the boat? Not a problem with the TZ X-5. Strong on power and more efficient under load than any other prop out there."

I think this would target a huge market of wake borders and surfers. "Efficiency under loads" should be what any avid boarder would want. However, it sure would be nice to have more data points to work with.

The Acme I posted on PG1, which is what was recomended instead of the 5 blade by the guys at Wakeprops was a 15x12. I'd sure be interested to see what it performs like for surfing and especially wakeboarding.....
