PYI Max-Prop EASY 2 Blade, Instruction Manual

7

6.  If you place the zinc bearing ring in its seat again, matching the “L” tooth with the hub 

reference mark, you have a left hand rotating propeller, on the contrary, with the “R” tooth 

you have a right rotating propeller as in Fig.6. 

7.  Replace the “Circlip” in to its seat.
8.  Tighten the nut and secure it with the locking-nut screws. 

9. 

Place the zinc again, and secure it with the 3 proper screws.

10. 

Be sure to change the pitch setting bolts to reflect the pitch setting for the new 

rotation.

PROPELLER USE

The Max-Prop EASY works automatically. By putting the transmission in gear the 

blades will 

engage in either forward or reverse 

(WARNING: do not change from forward to reverse and 

vice versa  when the engine is running at high RPM)

 and feathers from forward position 

when you turn off the engine and lock the shaft.    

The best way to feather the propeller is:

•  Power at 2 to 3 knots in forward.
•  Kill the engine while still engaged in forward. 

If your propeller has been greased properly it will feather in a fraction of a second as soon as 

you stop the shaft from freewheeling. 

DO NOT

 kill the engine while in reverse. In this case the 

blades will be in the reverse position and cannot feather. You can actually use this feature to 

drive a shaft alternator, or regenerate with an electric motor.

Modern transmissions are either mechanical or hydraulic. With a mechanical transmission, the 

best way to stop the shaft freewheeling is to engage the transmission in reverse 

(WARNING: 

engage the reverse only after the engine has stopped completely)

. With a hydraulic 

transmission you must shut off the engine while still engaged in forward. The remaining 

hydraulic pressure will in effect lock the shaft for a few moments, enough for the Max-Prop to 

feather.

MAINTENANCE

•  The p

ropeller must always be completely filled with recommended Lubrilate 130AA grease. 

The propeller should be greased at least once a year. This can be done with the boat in or 

out of the water.

•  Make sure that you always keep the zinc anodes in good condition. They must be replaced 

at least once a year, even if they still look ok. The propeller must be protected by a lot 

of zinc, so also use a zinc on the shaft when possible. When replacing it make sure that 

you clean the surfaces between the zinc and the propeller shaft in order to have a good 

electrical contact.
