Sunday Scenario....ProMax Food For Thought

[QuickBullet]

I've heard many say that the ProMax Prop is 1-2 mph slower than this one and that one.
Well, we all know that there's a trade-off on most anything when it comes to performance, whether it be horsepower gain, engine height, set-back or propellers.
I'm just gonna throw this out there!
Take 2 identical boats....set-up exactly the same except 1 running his favorite Top End Prop set to it's best engine height, and the other running a promax, set to it's best engine height.

SO....say the "Top End Prop" is 2mph faster on the big end.....OH LET'S GIVE IT 5!
Do you realize how much lake the "Top End Prop" will have to run to catch up with a 1-2 second holeshot along with awesome zero to 80+ acceleration???
Not to mention the awesome handling characteristics......Yes, You might guess I love my ProMax Props and the Best Thing......I can and do run'em as my fishing props! The trick here is to have 2...one for haulin'da Load and one for haulin'da A$$!!!!
Jus'Sayin....Y'all Hav'a Great Sunday!!!

I think you may be onto something. My trophy prop was great top end. A little slow out of the hole and mid range. It did carry a load at top end though. It was too bad handling either. Why the crap hasn’t Merc changed the metal in those props to keep them together is what I question.

Here is a vid of a stratos running 80mph vs a stratos running 74mph. At the 3min mark we walk him down and pass him. He had a good mile head start. This was 6mph difference. 5mph is HUGE. It took us 2min30sec to pass a boat that had a 1 mile head start.

Promax are OK holeshot at best. With your theory you should be running a bravo 1 IMHO. A bravo 1 will DESTROY a promax out of the hole.

I am hoping that with a little adjustments that I may get my 1mph on top end back. I was really scared when I purchased my new prop. I was scared to death I had spent a lot of money and it would not be something that didn’t work. So when I made my first run I really noticed in just a few seconds how hard the pro max was pulling. I also notice Cecil just a second or two after that how it handled. This was not something that was like well I’m not sure or maybe it’s a little better. It was a noticeable difference immediately.
Now granted I have tried very few props and I’m sure others maybe just as good. I am just giving my results compared to my trophy that I had run for 13 years.

No, it's not as huge as you think! Evidently the guy slowed down at some point or somebody lied about their speed?
This does not consider the holeshots but at speed, figures don't lie:


Boat-1 @74mph=108.53fps= 1.233miles p/min..
In 3 mins it will have traveled 3.699 miles, (1 mile approx every 49secs).


Boat-2 @80mph=117.3fps= 1.332miles p/min..
In 3 mins it will have traveled 3.996 miles, (1 mile approx every 45 secs).


Boat-2 will only be gaining .297 or say a little better than 1/4 mile for every mile!
Also Boat-1 had the 49 second head start so he'll be approx at mile 4.932 when Boat-2 reaches 3.996!



Give Boat-1 the 49 second, (1-Mile), head start and Boat-2 will never catch Boat-1 in 3 minutes....NOT Possible!!!

As far as B-1 holeshots, yes B-1's are bad to the bone but the PM "on my boat" is ALSO bad to the bone plus without question will out accelerate and handle better than the B-1's I've ran!!!

When passing the last boat, your partner was rowing. I busted up laughing! Something we would have done.

Lol I busted out when it got to that too.

Lol when I was having issues with my motor I had to borrow a 16 foot with a 75hp. When he had passed me he was rowing and laughing. Figured we would return the favor next chance we had

You don't realize how much speed is a advantage in a tournament tell you drive something that does 40mph WFO. We have some tournaments that spots are 20 miles apart, you don't even think about it in a bullet you just make the run.

Ok here is for the let off comment, this is from his view. Don't hear no letting off. 74mph with a 250/21 stratos isn't hard to believe esp with a child in the passenger seat. We had a well setup 200sho/19 foot stratos with one of my "topend" props 28p BC performer.

Just a FYI, the last boat we passed was a tr-20 with a 225 proxs, he goes 68mph, With your math we should of never passed him either.

From almost 40 years of Drag Racing in my past I'm fairly aware of fastest vs. slowest and what it takes to overcome somebody in a slower vehicle......Laws of Physics apply to boats as well as cars.....Math is math and it's also fact!!!
BTW, Love the Vid!!



The World we live in is not flat!

[QuickBullet]

The only way you could have passed him at the 3 min mark without him letting off would be for him to have had a lesser amount of head start!
You can figure his approx head start by knowing the numbers y'all drew and the takeoff interval between boats knowing that he was traveling 49 seconds per mile....of course to be more exact you'd have to figure in the time it took you both to go from zero to max speed.

QB where did that video of your holeshot with the promax go?

Exactly why haven't they?

When my old Stratos was in the shop and I had to resort to a borrowed 18’ tracker with a 60hp, I found out the difference. It sucked! lol

Vid must be in fast forward then, i seen one of those recently someplace .

[QuickBullet]

Guess you boys up there just see faster than us gud'ol boys!!!
Do you remember this post was originally about ProMax props?
I knew this would turn into some shxt when I posted it....seems it always does!
According to some I evidently don't know anything about boats, even though I was driving one well before a bunch of ya's were born!!!

BTW, I didn't think they'd quit teaching math in schools yet??
Reminds me of a problem we had when I was in aircraft school getting my Federal A&P license that's for some reason always stuck in my mind:

A helicopter takes off and is flying 120 mph. Two hours later, it is determined that the helicopter will need to be escorted on its journey. How long will it take an F-14, traveling at 900 mph to catch up with the helicopter?
Answer: It will take 2 hours and 18 minutes....but with your figuring he might catch up in 3 mins!!
Do The Math on the boats....ooh, I've already done it for you!!
The answer is at those speeds you refer to, it will take you 3min & 42secs to catch him and y'all will be at 4.93 miles from the start!
He did not have a 1 mile head start as you say! ;)

[hyperflow]

Anyways i showed a extreme case where a boat actually has a head start. You posted not that long ago you were not even comfy driving your boat wide open. Now your giving advice? Before giving false advise you should get some seat time in your boat and try a bunch of props and come back with some real data. Not prop slip calculator pictures and mathematical formulas.

[QuickBullet]

HAHAHA, Marty I'm not comfortable but that don't mean I haven't had it to 101, I'm always uncomfortable when I'm running above 80!
The advise I give is from my own experience and is FACT, and as far as props, in the 2 years I've owned this ride I've just about covered the bases from High 5's, Old Bravos, New Bravos, Tempests, Trophy's, Pro ET's ProMax's, X-OB and Performer!
Living right here on the lake I'm in this boat about 300 days out of the year.....how much seat time do you suggest before I can drive a Bullet?
This whole post was about MY opinion of a ProMax on MY Boat, and the amount of water that can be covered with a 1-2 second plane time and extreme acceleration, compared to a lazy holeshot and average acceleration.
I wouldn't be telling peeps you gave a MILE head start unless you did!
I'm thinkin' enough has been said on this subject, I'll post a vid of 8-10 fantastic ProMax holeshots as soon as I get some play time to do'em......then y'all can beat up on them!

I'm running a 30 pitch promax on my boat for now and have been pretty pleased with it so far.

You posted 6 months ago "one day ill mash it" Running 90mph with no life jacket, 6 months later you tried all these props. You post here every single thing you do but posted nothing about any of these so called props you tried apart from a promax?

Also where did you sell all these props? odd you sold some promax on here but sold nothing else?

Post a vid of your boat running 101mph "heavy load" as you said. Then i'll eat my words and apologize.
