THREE BLADED PROPELLER RECOMMENDATIONS

1.  Use this chart to find the approximate, three bladed propeller size for your vessel. Use this chart as a guidline only. 

    Contact factory for actual propeller recommendation for your vessel and for medium and continuous duty propeller sizes.

2.  In the left column find the engine, then find the boat speed your builder expects from an engine of this HP on the top line.

    Locate the point where the two columns intersect for propeller size and shaft rpm. 

 

 Example:

  L668D in a 18 kt boat uses 1:1 gear ratio and turns a 16 X 14 prop at 2500 rpm.
