    Here are the results I achieved with all props, starting with each at AV plate level with hull with 5-1/2" setback (jackplate) with no pad. I raise in 1/4" increments until RPM rises with no speed gain or control becomes an issue.
    Again, this is an aluminum Deep-V with a 200 'Rude on the rear and Nauticus Mobster-tabs.
    Lake conditions were very good, with a very light chop of 3-6" with an air temp stabilized around 62 degs F.
    Boat was re-fueled after every run, and 400lbs of sand tubes were added to simulate 3 aboard.

    Prop #1. Turbo1 19P........0-30mph 2.9 secs 0-50mph 7.5 secs. Top speed 53.7mph 5950RPM 10.5% slip
    #2. Apollo 19P Large blade....0-30mph 2.9 sec 0-50 7.9 secs. Top speed 52.6 5910RPM 11.1% slip
    #3. Enertia 18P.......0-30mph 2.8 secs. 0-50mph 7.7 secs Top speed 53.1mph 6020RPM 7.85% slip
    #4. Enertia 19P.......0-30mph 2.9 secs. 0-50mph 7.5 secs. Top speed 54.4mph 5990RPM 9.4% slip
    #5. Mirage+ 19P.....0-30mph 3.1 secs. 0-50mph 8.0 secs. Top speed 52.4mph 5960RPM 11.7% slip
    #6. Vengeance 19P..0-30mph 3.0 secs. 0-50mph 7.9 secs. Top speed 52.4mph 5970RPM 12% slip
    #7. Rapture 19P.....0-30mph 2.9 secs. 0-50mph 7.8 secs. Top speed 53.0mph 6000RPM 11.4% slip
    #8. Stiletto 19P.....0-30mph 2.8 secs. 0-50mph 7.9 secs. Top speed 53.1mph 6000RPM 11.3% slip
    #9. Lexor (solas) 19P.0-30mph 3.0 secs. 0-50mph 7.9 secs. Top speed 52.6mph 5965RPM 11.58% slip
    #10.OMC Raker 18P...0-30mph 3.2 secs. 0-50mph 7.8 secs. Top speed 51.9mph 6010RPM 10.7% slip.
    #11.OMC Raker 20P...0-30mph 3.6 secs. 0-50mph 8.1 secs. Top speed 55.8mph 5830RPM 10.45% slip


    Final placing....
    MWC Apollo 19P large-blade

    0-30mph..........4-way tie as the second quickest in acceleration.
    0-50mph..........4-way tie as well, but number 4 to 50mph...not bad considering the props tested
    Top speed.........Only 1.8mph slower than the fastest 19P tested
    Ave. slip ratio........10.74%, #3 in comparison to all 19P's tested.

    This is just a comparison of "some" 18-20P props and not all fall into the same catagory.
    I feel the Apollo has the ability to be above average in performance and is targeted at the medium price-range of the SS market and I see that it hits that mark in performance and price.



    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.

    Re: Walleyehed's Testing

    Thanks guys. Sorta confusing coming from Tail Gunner rather than Kenny. Did you guys work together on this?

    I guess, unless you are a purist out to get every 1/10 mph out of your rig, regardless of cost, the Apollo is the way to go.

    If you are new to boating or have a new boat, a knowledgeable friend could show you how to operate your boat and save you a lot of grief, maybe some money, and maybe your life.

      This was a sticky prior to the new software, kinda go lost in the schuffle.
      It's all Ken's work, i just found the link and got her back up so hopefully the mod's will pin it...

        Re: Walleyehed's Prop Test Results

        I love this sort of comparison; it puts things into prespective.

        If I ski, the difference between 2.9 sec and 3.6 sec in 0-30 mph translates into something..., strong hole shot, get my fat butt up outta' the water! If I fish offshore..... it doesn't mean much at all, unless I'm big and heavy or if I want to be up on a plane at a lower speed, but both are necessary considerations.

        If I'm racing or competative fishing in a bass boat, the difference between 51mph and 56mph top end is huge! Again, if I'm fishing off-shore, it doesn't mean much at all.

        It's not all about the numbers, but what the numbers mean in real world application. The differences depend upon the application. Z,

          "if I'm fishing off-shore, it doesn't mean much at all."

          Actually, the faster, more efficient props(less slip, better MPG) are a HUGE plus in off-shore....(as long as they will run at the top of the RPM range)that's where the efficiency really shines through.
          Just the fact these lower slip props hold better in adverse conditions makes them good choices for off-shore use.

            You can run off shore at WOT? Different boats, perhaps (I have a light weight 21' Sea Pro CC with 150 Johnson). I find that I'm always throttling back and forth, up and down, trying to stay on a plane vs. jumping off the back of the swells and beatin' us and the boat to death. My Viper excells at WOT. It grips and hauls a** at WOT! I love it when I can out run my friends with bigger engines. But I can't run that way offshore. Get us outside in the slop or with a big swell, and the low end slippage will not let us get up and stay upat a comfortable speed. I'm considering a four blader so I can grip and go at a lower speed and lower RPM. It is all in the application. I'm hot to trot in the river and suck wind offshore 'cause I can't run at the WOT that the Viper excells at.
            I would dearly love to hear advice to the contrary, as I ain't any kind'a prop pro and I ain't lookin' forward to seending the $$$. If I have it all wrong, PLEASE tell me! Thanks! Z

              Re: Walleyehed's Prop Test Results

              Maybe I was not real clear about efficiency....By using the "TYPE" of prop that creates a lower slip ratio, you effectively gain more "Bite".
              As I've said many times, speed is only a result of the set-up...this does not mean speed is your goal....in this case, mid-range cruise efficiency is the goal...a higher tech prop will, in most cases, provide just that.
              Yea, we can run a prop with little if any cup in the right place, to get the R's up, but control and efficiency are lost in doing so.
              I should also add...By setting up with a prop that allows the top of the RPM range at WOT, the cruise will increase in efficiency.
              As for the Viper..well, it's a good all around GP prop. If I had to choose a prop for my rig for what you are doing, I can't say the Viper would be on my list....It's a newer design blade than the SSTII's (Black) and really intended as a step-up from the standard aluminum in BRP/OMC.

                Thanks for the clarification. I once had a statistics professor who used to say, "There are liars, there are damned liars, and then there are statistics! I can make the numbers say any thing I want them to!" It's often difficult to translate the numbers into actual function. That's one of the reasons I love this site. I can read the numbers, you've run all these props! Z

                  This test was for the MWC Apollo and was wrote up as you read it to go to MWC.
                  Props tested to present date are about 600 now.
                  The test posted before this one had about 30 Load pushing, heavy boat props and about 25 High-performance wheels..all SS. I should find it in my saved documents and re-post. It's a couple of years old, but most of the props run are some of the most common yet today, again, all SS props, but this test did not include the Apollo, Merc Enertia and several of the new Turbo designs.

                    I've decided to leave these test results and add the new as I get them done....there are an incredible amount of views for this thread and I don't want to remove any useful info.
                    I'll add as the paperwork gets done.
                    Thanks.

                          MY Thanks to Walleyehed and Tailgunner for the info and keeping it up on the site.

                          I'm new to this forum, and I posted a question two days ago "HELP IN CHOOSING A PROPELLER" With the suggestions I have received, and these test results I feel fairly confident that changing from the 3 blade Laser II 14 1/2 X 19 to the four blade Apollo 14 3/8 X 18 will improve my hole shot and mid range performance. If you have anything to add It would be appreciated.

                          Thanks again for keeping this info posted. I would have definitely missed it.

                            you have to remember that your carb jetting and altitude have everything to do with prop selection. all of the tech facts does not mean anything when running at different altitudes

                              Actually, prop selection is a matter of jetting for the proper altitude and temp, then the final timing adjustments, then prop for the same RPM you have at any altitude as long as it's the top of the rpm range.
                              The "TECH FACTS" remain the same regardless of altitude.
