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:
2, 3 & 4 Blade Easy
Available for shafts 3/4" to 1-3/4" or metric equivalent also available for SailDrives.
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.
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.
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.
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.
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.
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.
