  • Page 6 1. INTRODUCTION Thank you for choosing a MAX PROP feathering propeller, EASY/ WHISPER / ® ANTISHOCK model. This instruction manual is used to answer your questions about installing and operating the propeller. Before installing the propeller on the boat, it is essential to read it carefully.
  • Page 7 b. Check the screwing length of the nut (refer to fig.1 where the screwing length is indicated with “X”). To check this we suggest inserting the propeller onto the conical end of the propeller shaft and pushing it against the cone of the shaft (carry out this operation without inserting the key).

  • Page 9 a. Insert the already assembled propeller onto the propeller shaft (refer to fig. b. Insert the nut into its seat, screw it in and lock it by using the two locking nut screws that must be inserted in their seats and then tighten. The nut tightening torque must not be too high (approximately 20/30 Newton/meter for propeller shafts smaller than 35 mm and approximately 30/40 Newton/ meter for propeller shafts larger than 35 mm).
  • Page 10 4. CHECKS TO BE CARRIED OUT BEFORE LAUNCHING THE BOAT a. Check that the propeller body is free to rotate with respect to the propeller shaft, so that the blades can move freely from the forward position to the reverse position and vice versa. To verify that this happens, hold the propeller body and the propeller shaft separately with your hands.
  • Page 11 5. WARNINGS FOR THE USE OF THE PROPELLER a. The reverse gear must always be engaged starting from the forward gear position. Therefore, before engaging the reverse gear, the forward gear must be engaged for a moment. b. In order to have the propeller blades feathered, the rotation of the propeller shaft must be blocked, even for a few seconds, while the boat moves forward with a speed of at least 5-6 knots and the propeller blades are arranged in the forward position.

  • Page 13 • Screw the grease inlet tube into the hole (the tube is supplied with the propeller). Start injecting grease into the propeller body by applying pressure. Keep the injection pressure applied until the injected grease begins to seep out of the propeller body both through its joints and the surfaces of the elements which, during operation, must rotate with respect to the propeller body (blades and hub).

  • Page 15 e. Fasten the puller (consisting of a perforated washer) to the zinc-holding ring by using special countersunk head screws. f. In each threaded hole of the zinc-holding ring, a countersunk head screw for locking the puller must be inserted. Check that all screws work together to hold the puller pressed against the zinc-holding ring.

  • Page 18 All the other characteristics of the propeller have negligible influence compared to the pitch and diameter.

  • Page 22 C. HOW TO ESTABLISH THE PITCH VARIATION In most cases it is not important to know the absolute value of the forward pitch and the reverse pitch already set, it is instead important to establish the possible variation you may wish to make. The user must first establish what is the target cruising RPM, and, consequently, what is the maximum RPM that the engine must reach at maximum acceleration.
