  • Description

    The Max-Prop Easy is a step forward in Max-Prop design. This propeller replaces the well-known Max-Prop Classic, facilitating simplicity for the customer without sacrificing performance. The Easy model’s main attributes over the Classic are: 1) ease of installation (simple bolt on to the shaft); and 2) flexibility of pitch adjustment without the need of a haul out.

    All the Easy models share the following features:

    • Easy bolt on installation
    • Externally adjustable pitch
    • Outstanding reverse
    • Low drag under sail
  • Two Blade Easy features:
    • Efficient forward power
    • Very low drag under sail
    • Available from 11" to 18" diameter
    • For shafts 3/4" to 1-1/8"
    • Best suited for all racing boats or smaller cruisers
    Three Blade Easy features:
    • Added forward power
    • Runs much smoother than a two blade
    • Low drag under sail (slightly more than a 2 blade)
    • Available from 12" to 26"
    • For shafts 3/4" to 1-3/4"
    • Best suited for 24’ to 55’ cruiser (medium displacement)
    Four Blade Easy features:
    • Outstanding forward power
    • Very smooth running (no vibrations)
    • Low drag under sail
    • Available from 14" to 26"
    • For shafts 3/4" to 1-3/4"
    • Best suited for 40' to 70' cruiser (medium to heavy displacement)

  • Shipping

    Please allow 3-5 days of handling before we can ship your Max-Prop propeller. This is to allow any time for boring and assembly.



EASY PITCH ADJUSTMENT

If your engine achieves either too much or too little RPM at max throttle, adjust the pitch to a higher or lower setting to attain the correct RPM. Pitch adjustment can be done in the water as the propeller does not need to be disassembled to change the pitch.


Outstanding Power

In forward the Max-Prop will offer 96% of the efficiency of a fixed blade propeller of the same diameter and pitch. The 4% loss in power can usually be eliminated by precisely matching the pitch of the Max-Prop to fit the boat engine combination. The three blade has a major advantage when going against heavy winds and seas, it will maintain the boat speed up to 30% better than the two blade.





Unmatched Reverse

The Max-Prop provides 80% more power than a comparable fixed blade propeller. The Max-Prop utilizes the same leading edge in forward as it does in reverse giving the propeller the same thrust in both directions dramatically improving control and power in reverse.

Max Prop review - pre install

I replaced a 13 inch fixed prop with a 13 inch max prop for my CAL 27 with 11 HP universal diesel. Unfortunately the blades of prop in the feather position are too large and do not clear the rudder. PYI suggested a direct exchange for a 12 max prop. I requested and received scaled drawing for 12” prop to verify will fit prior to exchange. PYI prepared drawings and sent to me via email. I scaled up to full size and verified 12” max prop will work with minor mods. I will have to shave up to 1/2” from rear of my strut to provide the 1/2” clearance required for water flow through cutlass bearing. You see, the hub of the max prop is longer than standard fixed prop and quite substantial. The max prop is quite impressive and hefty. The grease kit is well made and complete. I am planning to replace the prop shaft with new ss alloy unit and will update this review after install and performance test.. in late spring. I am giving 5 stars for customer service and visual quality of max prop. Happy sailing.

Great prop! Cannot wait for next summer to try it out...winter will be long. Super service from PYI team, perfect advice of sizing and pitch.
Thanks!

Excellent Prop - Better than expected

The Max Prop Rocks! It's really smooth and efficient. I bought the 2 blades for minimal drag and was expecting some vibrations as my boat (C&C 34+) is somewhat notorious for vibrations on 2 blade props. Much to my surprise it's almost as smooth at my 3 blades fixed prop and very close in forward performance as well ( And much better in reverse of course). I get within 1/10 - 2/10's of a knot from calculated max hull speed at my engine's cruising RPM and the engine can rev-up to max RPM when needed. It's tremendously smoother than the Old Martec it replaced and the Flex-O-Fold I ended-up sending back to Denmark prior to purchasing the Max Prop.

MaxProp Easy

Very easy to install and adjust pitch in the water. Installation using scuba; adjustment using mask/snorkel only. Performs very well in forward and reverse.
