SOLAS STAINLESS STEEL 13 X 21 PITCH PROPELLER

Description

WHICH PROPELLER PITCH IS APPROPRIATE:

1. Check the RPM range recommended by the Outboard Motor Manufacturer in the manual.
2. Check the maximum RPM range by reading the instrument panel to determine the optimal pitch and speed.
3. If maximum RPM exceeds the recommended range, lower the RPM by using one level higher pitched propeller. Repeat this procedure to figure out the appropriate pitch propeller.
4. If maximum RMP is lower than the recommended range, raise the RPM by using one level lower pitch propeller. Repeat this procedure to figure out the appropriate pitch propeller.

How to Count the Splines On Your Shaft:
The image below shows how prop shafts generally look, the marked area is referred to as the splines. To count these splines correctly it is recommended to mark the first spline you are counting and stop once you reach the marked spline again.
