PYI Max-Prop EASY 2 Blade, Instruction Manual

INSTRUCTIONS

1. 

Fit the propeller onto the propeller shaft, just like a fixed propeller. Be sure that the thrust 

washer is on the spline before fitting the Max-Prop onto the spline. Without the thrust 

washer the propeller will be loose fore and aft on the spline, and will damage the SailDrive 

or propeller.

2. Tighten the nut onto the spline. Align the holes in the back of the nut with the groves in 

the central hub, so that the two shaft nut lock screws can be tightened in place. Insert and 

tighten the center locking bolt into the back of the nut. Secure it with the set screw for the 

center locking bolt.

3. Fit the zinc and secure it with the three allen bolts. Make sure that the zinc and the 

propeller are clean to insure good contact.

4. 

Fill the prop  with marine grease (supplied) using a grease fitting (supplied) inserted into the 

grease holes on the side of the propeller marked “GREASE”. The Max-Prop Easy propeller 

works properly only if the central body is completely filled with the correct grease. Verify 

that the grease is oozing from the rotating joints between the central part and the hub, so 

that all of the moving surfaces are perfectly greased. The grease used must be a type of 

grease approved by Max-Prop so it will remain fluid after years of use and will not get too 

stiff in cold water. Follow steps 4.1 through 4.9 on page 3. We recommend Lubriplate 130AA 

calcium based grease.
