    Default Tested the new Mercury Pro Max

    We tested the Mercury Pro Max prop

    Well it lived up to the hype

    Our team has done extensive prop testing over the last four seasons

    With many of the top named prop companies

    The Mercury Pro Max non labbed prop worked very well

    Its a over/under 4-blade prop, great hole shot and top end

    but what is really great is the hook up in corners !!!

    Its Mid and Top end is close to our BBlades props

    I love my BBlades props !!! and they are great to work with

    I will have them do the lab over Mercury, not that Mercury doesn't do a good job

    But BBlades is really great to work with and can figure the tweaks you need.

    Last year at the Parker Enduro we ran three different props each having a advantage and a disadvantage over the other props

    It was funny that three different props and three different drivers could all avg the same lap times for 300 miles

    After the race we did more testing, we were forced to race with the prop shaft height even with the bottom

    Just raising the prop x -dimension up, had a dramatic effects on overall performance and speeds on some of the props

    All testing was done on a 19 Cougar w/300xs best speed 113 mph

    Best props we found so far
    BBlades 4 blade Mid range and top end !
    Hackney 3 blade Top end 112, but trim sensitive
    Hackney 4 blade 34 pitch 113 MPH
    Hydromotive 4 blade Overall control in rough water ie Parker 300
    Mercury Pro Max -4 blade Across the board performance
    Mercury Pro et 4 blade Mid range and top end

    Thank you for the write up. I have a 19' Eliminator Daytona and it is very difficult to find information on these hull types. Were the speeds you have listed at even with the pad?

    Thanks, Geoff

    The 19 Cougar, will run 105 even with the bottom.

    We also have a 21 Cougar w/2.5 Merc runs 114 MPH 1 1/4 above the pad

    And we also have a very light 19 DCB/ Daytona that has run 118 in the Quarter mile tops out at 127 MPH w/ 2.5 drag w/nos

    There are a few different bottoms on the 19 Daytona.We have a double stepped
    and notched transom on ours 1 of 1 that I know of

    The Cougar and Daytona have completely different bottoms
    apples and oranges

    The Cougar will eat a Daytona in rough water conditions !

    I have a 2.4 Bridgeport on the boat now and will be switching to a 300X this winter. I also have a 21 Liberator. Both boats seem to favor the same style of props.

    My Eliminator is heavy, I have not weighed it but its definitely not a light layup. It has the rounded hump on the bottom of the center pod. Not sure why they do that?

    I ran with a 19 Cougar this summer. As you say, the bottom of his boat was different from mine. He had no interior and a little more horsepower, so he was a little faster. His boat walked pretty bad when running two of my drag 4 props between 90 and 100. It looked scary to drive. Do you have the same issue? Is it something you have to drive through?

    Our 19 Cougar and Daytona are both center steer boats and
    having the weight centered is the way to go

    The hull will take a much better set and give you a rock solid ride @ speed

    We our changing the 21 Cougar to center steer and putting a big Opti Max on it

    I think you and your friend should try the Pro Max props

    Do you add holes like the bravos have for slip?

    We ran the Pro Max box stock

    The under/over hub allows for a fair amount of slip out of the hole and

    works pretty good.

    I would like to experiment with trophy prop vent plugs maybe 2 per blade 8 total

    will have to modify the prop for them. This would allow us to dial it in to our standards

    We modified our 30 hydromotive for Parker with two holes per blade for a better hole shot

    As for Bravos we were modifying them with holes and cutting off the diffuser rings
    years ago

    I think Mercury copied us when they came out with the O/B bravo prop

    The O/B bravo runs a 10-12 % slip and the Pro Max is around 4 1/2 to 5 % slip

    The best thing I can say about a Bravo is they can run hundreds of hours without breaking but the performance sucks
