ROUND 2
-
Well yesterday I took my boat over to Lake Lanier to spend the day at BigGrizzly's AGAIN testing props. Well it was 85 degs and approx 70% humidity, altitude is 1063' ASL, the water conditions were approx 3-4" chop wind around 5mph. To set the scene my boat is a 2001 22 classic w/454 Mag mpi w/bravo 1 100% factory stock. We tested 3 props bein that Randy sent the other props off to others on this board for them to play with.
We tested again for base line my favorite prop, Turbo 1, out of the three that I have (Mirage+ 14.625 x 23p 3 blade, Turbo 2+2 14.25 x 24p 4 blade, Turbo 1 14.25 x 25p 3 blade).
-
The Turbo 1 14.25 x 25p x 3 blade this time went
-----3000rpm----44mph
-----3500rpm----50mph
-----4000rpm----56mph
-----4500rpm----60mph
MAX 4700rpm----67.7mph vs 64.8 in first test
-
-
The Turbo 2+2 14.25 x 24p x 4 blade went
-----3000rpm----38mph
-----3500rpm----44.7mph
-----4000rpm----53mph
-----4500rpm----58mph
MAX 5000rpm----65.8mph
-
-
The Mirage Plus 14.625 x 23p x 3 blade went
-----3000rpm----40.9mph
-----3500rpm----46mph
-----4000rpm----53mph
-----4500rpm----56mph
MAX 5100rpm----68mph
-
Well the M+ and Turbo 1 are really close 68 to 67.7mph and 400rpm's difference well it looks like a Turbo 1 24P will be needed to test and the Turbo TXP would have been nice to test again to see the mph it would have attained on this day of testing, but that will have to wait for ROUND 3
-
The info below was from the first testing, the Turbo 1 this time was 2.9mph faster so day to day testing has a big variance, the weight in the boat was the same but the temps, humidity and water conditions were the variables, the temps the first time out were in the low 90's, humidity in the 30-40 range and water conditions were calm and flat no chop at all. We only did top speed logging the first time. The other props from the first test were not available to test this time. Oh well next time.....
-
Winner Round 2----Mirage plus 68mph followed by Turbo 1 67.7mph a really close one this time.
Winner Round 1----Turbo TXP 67.9 by a long shot.
-
ROUND 1
Base line Turbo 1 14.25 x 25p x 3 blade-- I can only spin to 46-4700 rpm with indicated (speedo) speed of 70mph which turns out to be GPS speed of 64.8mph.
-
Turbo TXP 14.75 x 25p x 3 blade-- 46-4700 rpm with GPS speed of 67.9mph
Turbo OSI 14.50 x 23p x 4 blade-- 46-4700 rpm with GPS speed of 65.7mph
Turbo OSII 15.00 x 24p x 3 blade- 46-4700 rpm with GPS speed of 65.4mph
Turbo Fusion 14.50 x 24p x 4 blade-- 4500 rpm with GPS speed of 62.2mph
-
Well as you can see the rpm's are all around 46-4700 with all the tested props except the Fusion which the motor could not swing.
I gained mph with all the other props from .6 to 3.1.
-
So 3.1 mph gain for just a prop change and all props were stock from the factory NO LABBING.
Testing is not done yet we are going to try some more props to bring the engine rpm's up to 4900-5000 to see if there is any more speed to be found.
-
Winner Round One TXP 67.9mph by along shot....

PS Thanks Again Randy
PSS And thanks for the ride in the Critter, Loud, smooth (except for that first jump) and different than the 22 ride.....
