Re: Walleyhead's Prop Testing Post
As this is copied from Wordperfect 10, it didn't format perfectly, I apologize for that...the prop, manufacture, rpm and speed are listed after each prop and if you read carefully, you can extract those numbers.
I hope this is of some use to all who read it. I learned many things about blade design during this testing and some designs are just not suited for some applications, but I did get a very good feel of how each design performs and where it is best suited.
If you have any questions, please, ask away.
Remember, these are all SS props.
PROPELLER TEST RESULTS
FOR 3-BLADE STAINLESS, THRU-HUB EXHAUST DESIGNS.
BY KENNY SANDERSON
2 PROPELLER DESIGNS WERE THE FOCUS OF THIS TEST
#1. WAS TARGETED FOR HIGH-END PERFORMANCE, THRU-HUB DESIGNS FOR HIGH-PERFORMANCE, OUTBOARD TYPE HULLS.
#2. WAS TARGETED AT THE HEAVIER, STERNDRIVE AND CENTER CONSOLE-TYPE BOATS WHERE LARGE BLADE AREA IS REQUIRED FOR BEST PERFORMANCE.
THE BOAT COMBINATION USED FOR THE TESTING IS AN 18FT., ALUMINUM DEEP-V WITH A 6 INCH JACKPLATE WITH TRANSOM MODIFIED TO HANDLE A 2.5L, 200HP EVINRUDE.
MOBSTER TABS BY NAUTICUS INC, WERE INSTALLED TO ALLOWED THE SPEEDS ATTAINED
DURING THE OPERATION OF THIS BOAT AND CREATED A SAFE PLATFORM WITH EXCELLENT HANDLING QUALITIES.
SOME PROPS ARE LISTED TWICE, NOT ALL PROPS WERE TESTED ON THE SAME DAY, BUT EACH PITCH GROUP WAS RUN ON A SPECIFIC DAY, SO DATA FROM EACH PITCH WILL BE UNIFORM TO CONDITIONS.
TEST CONDITIONS ARE AS FOLLOWS FOR THE DEEP-V ALUMINUM PLATFORM.
FOR LOAD SIMULATION, SAND BAGS WERE USED FOR WEIGHT, POSITIONED WHERE PASSENGERS WOULD NORMALLY BE.
FOR THE HIGH-PERFORMANCE PROPS, 19P AND UP, 200LBS OF SAND BAGS WERE PUT WERE THE PEDESTAL FOR THE LEFT SEAT WOULD BE.
FOR 17P AND SMALLER, 600LBS OF SAND BAGS WERE ADDED TO SIMULATE A HEAVIER TYPE BOAT.
FOR THE LARGE BLADE AREA PROPS, 200LBS OF BAGS WERE PLACED IN THE LEFT SEAT POSITION AND 400LBS IN THE REAR WITH AN ADDITIONAL 200LBS FORWARD OF THE CONSOLES.
ALL REQUIRED GEAR PLUS 175LBS OF TACKLE, A 24 VOLT 62 INCH MINNKOTA TROLLING MOTOR WITH 2 GROUP 31 BATTERIES WERE ALSO LEFT MOUNTED TO SIMULATE ACTUAL, REAL-WORLD CONDITIONS.
PLEASE KEEP IN MIND, MY RESULTS ARE UN-BIASED, I WAS NOT PAYED OR REIMBURSED IN ANY MANNER TO TEST THESE PROPELLERS, THIS TASK IS ALL MINE AND TOTALLY INDEPENDENT OF ANY AND ALL MANUFACTURERS.
THE HIGH-PERFORMANCE PROPS WILL LIST TOP RPM AND SPEED VIA GPS. THIS LIST WILL ALSO INCLUDE VENT HOLE SIZE IF SO DESIGNED BY FACTORY.
HOLE-SHOT CHARACTERISTICS WILL BE LISTED AS WELL.
IN SOME CATEGORIES, THERE WILL BE PROPS OF 1" TO 2" DIFFERENT PITCH AS REFERENCE PROPS FOR COMPARISON.
ON THE FOLLOWING PAGES, THE BOAT, PROP MANUFACTURER AND SIZE WILL BE LISTED, WITH SPEED VALUES AND RPM. HOLE-SHOT AND/OR VENTING HOLES WILL BE NOTED AS WELL. ALL PROPS WERE RUN TO MAX EFFICIENCY AND ONLY TOP FIGURES WILL BE LISTED.
