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.
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.
Just like other Max-Prop propellers, the Easy feathers to a low drag position while sailing. Under sail the Max-Prop will increase sailing speed by about 15%, the largest difference being noticed when sailing in light air. When sailing with a fixed propeller the vessel has to overcome the fixed blade drag, installing a Max-Prop maximizes sailing performance.
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.
I replaced a fixed 3 blade. The recommended maxi prop by PYI was the same diameter. The blade side is wildly different however. The Maxi prop does not generate nearly the same thrust as the fix blade. More sea trials will be needed to see if this even works. The staff at PYI were a bit unorganized so you need to keep on them to be sure the order is processed.
My experience was great, from the selection process to ordering the right unit Fred Hutchison was very responsive to both emails and phone calls. The commitment on the shipping date was helpful in planning my haul out, PYI was just a great experience. Love the change in performance.
Thank you, received my max prop. The team at pyiinc are really professionnal. They gave great recommendation to replace my existing propeller, lots of exclamation. They took the time to answer all my questions. Now waiting for next summer to try it!
The only thing that didn't live up to the name "easy" was getting the old prop off.
The new feathering prop is a gorgeous work of craftmenship and it took less than an hour to install.
The boat is now ready to go into the water, looking forward to my first sail without a dragging prop.
Service for the purchase was excellent, a couple emails and a phone call from them to verify the dimensions, and a little over a week later the perfect prop arrived. Thanks
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.
