INTRODUCTION

Thank you for having chosen a Max-Prop automatic feathering propeller for your vessel. This 

instruction booklet is designed to answer all your questions on installation and use of the Max-

Prop. Please read he instructions carefully and verify the correct working of the propeller before 

installing it on your boat.

IMPORTANT NOTES

The propeller is shipped already assembled (unlike Classic Max-Prop models). The rotation (left 

or right hand) and pitch has been determined at the time of the order and is therefore ready 

to be fitted on the shaft. Please note that Max-Prop parts are NOT interchangeable so make 

sure that if you receive more than one propeller (for a catamaran for example) you do NOT 

interchange parts.
