Quad IV Results (Long)

[carolina killer]

I first ordered a 29 Quad IV X O/B Super Special which means it has added cup to the trailing edge and tip cup added it was to much prop for my setup so I sent it back and swapped for a 28 Quad IV X O/B Super Special Outboard Cut what they call there SST version.. It still wasn't quite right it had some porpoising and I felt it had to much tip cup as well which both combined took some speed and rpms away..
I called Mark and told him what it was doing and that the 28 Trophy and the 27 TRO4 and a 28 Bravo1 that he worked has been the only three props that I have run out of 15 different props that did not have some sort of porpoising issue on my 2006 2100 Gambler.. He said I know what do to do the prop to stop the porpoising and he agreed that it should have some tip cup taken out as well..
I wrote all the info down and sent it to Mark I got it back yesterday and I went and ran it today.. Talk about a different prop there was no porpoise whatsoever and the mid-range was even stronger than before and it was 1 mph faster than my fastest prop which is the 28 Trophy that Mark had worked for me..
The water temp was 85 degrees
Air temp 86
Humidity 50%
Light wind
I turned it 5700 at 81.1 gps
I turned my 28 Trophy 5680 at 80 gps
At 850 feet above sea level
That is with a stock 225 Pro xs
My speeds are down right now around 2.3mph because of the hot weather the reason I say that is I ran the worked 28 Trophy in cooler temps 82.3 gps..
So if the Hydromotive holds the same in the cooler weather that means it will be running 83.4 gps..
All these speeds have been with a full fishing load with drinks and ice in the cooler and around 1/2 to 3/4 tank of fuel..
I must commend Mark on a fine job he did on reworking the Hydromotive and making a very good prop a killer prop...

Sounds like ya got good results Terry, wouldn't Todd of adjusted it a time or 2 for ya to tweek it to your rig?? Usually that comes with the purchase of a new prop from them... Louis

Terry, glad you have finally dialed in the Hydro. Thanks for posting all your numbers. I wish more guys would do the same. It helps keep people in check and not stray from the truth. How did it handle in turns as compared to the Trophy? Congrats and Thanks.

[carolina killer]

It handled the turns real well... There is a little bit of wheel torque at mid-range speeds..

Great info Terry... Mark does know what he's doing.

Question for Mark if he reads this and/or anyone. Is it easier for Mark to pitch up or pitch down. If a 28 isn't hitting the limiter, is it easier for him to work the prop and pitch it down or, if you buy a 26 and its all over the limiter to work the prop and pitch it up. In other words, do you want to buy a bigger pitch or smaller pitch prop if you're just not sure what prop will work best and you're putting down the hard cash. I have a 27 Trophy, a 28 TR04 and a 30 Bravo, none have hit the limiter. If I want to buy a big buck Quad IV or ET do I go to a 26 and let Mark go from there? decisions decisions

[carolina killer]

I have always been told that it is easier to pitch down than it is to pitch up... BUT there are limits to how much pitch one can change in a prop and from what I understand it's about a pitch and a half tops..

[Largemouthlou]

Sandy, how far from the limiter are ya??? You really don't want to be hitting it anyways..

I think the 28 or the 29 would better for your combo and let mark tweek it.. I would call Mark and ask him which he thought would be the best...
