No, I'm not giving it away. Let's just say it chages the boats attitude if the stern is loose or skaty.

I have wondered about these Maximus prop myself as I have experienced the following
2007 35 Lightning ICBM with 496HO, shorties and Maximus ran 82 mph
Same set up with Herring 6-blades ran 88 mph
Maximuses have been tested on my 29 Fever in both 32 and 34" pitch. This boat is balanced totaly different, so it do not make a fair comparison. BUT they tend to make the bow go up and down at full speed.... If I drop the trim a bit, the bow sucks down and I loose 4 mph. It is neccesary with more trim than on the std 4 blades, but that makes the boat slower...
Grip is phenomenal at speed, but they have spun loose more from standstill than 4 blades.
The Maximus blades seem to flex quite a a bit. I hav one centimeter (just a little less than half an inch) space to the shower pick up, but after the prop test, the blades were damaged by the pick-up.... Is this normal????? I have heared the Herrings are forged? Does this help?
The 35 ICBM is really awesome to run..... Put the throttle all the way up, and take a nap, the boat runs like on a railway track! :-)

The Herings can be faster than the competitive propellers when compared to the competition in stock or standard Lab configurations. We can create identical or similar thickness curves with non Hering propellers and achieve equal or better speeds. In short.....thin to win. We have known and done this for years. When I was first starting out with Dennis C. at Merc Racing, I would ask why we don't make all our #6 props at a KILO thickness for our race teams. Dennis would say "It is better to finish the race than to fly a blade." We can make disposable props out of the Maximus and and they will haul a$$. We have done it on different P class boats and they have won many races. A balance between speed and longevity is often the best route.
Fountain is and has always been about speed. In fact, they can even be found to have exaggerated on the performance reports. I'm sure nobody has experienced that before. HAHA. Staggered engine set ups used to be done to get the props deeper and engines deeper for off shore racing (bet alot of folks didn't know that) now they put the drives up so high you HAVE to use 6 blade props just to get on plane and control slip and driveability. When will the boys come back to earth (or at least the water surface) and realize 4-5 blade props can be as fast or faster with a little water around them?

Brett I was thinking the same thing trouble getting on plane,Ive got a buddy with a 42 stagger 525,4bl 32,its a beoch to get on plane ,when watching it you can hear it slipping and straining.but there faster

Are you saying the same boat here?
Or different boats set up the same with thw difference being the props?
And yes they are "on a rail".

The boats were two different boats, but the numbers are true.
The first 35 that Fountain staggered did 90 mph with 496s.... Now, they seem very nose heavy. "Bow-lift" / the boat to air out high is non-existent. However, they run fast. It is just so strange not to get the bow loose when trimmed out. But ONE HELL of a wave crusher! The owner used it in a offshore race without having any racing experience. Just cruised a 40 minute race in 4 ft sees at WOT. Pretty impressive. But the boat never performed the 86 mph as in the performance report. Only 82. Strange!

Bow lift is made by pushing the transom down. Props too high, no leverage to the transom no bow lift. Staggered set ups with real high "X"s can't get leverage up behind the transom. Otherwise it must have natural lift from air entrappment or it has to be a V hull going so fast their isn't any boat in the water. Stepped V's are supposed to run flat on airreated water and handle ultra high "X"s but there is a limit and we are seeing it more and more.
Changing diameter, rake, cupping and most importantly prop depth will change bow lift. Stock Maximus props have decent bow lift for a 15 5/8" 5 blade propeller because the have 30 degrees of rake and cupping in the right spots. But, all that 5 bladed blade area has to lift the transom so..........it may need to be modified for the specific application and the rotation and or depth adjusted.
High is great for top speeds in the right condition with a perfectly weighted race boat but, not always good for the family truckster.
