What does WOT mean?

WOT stands for Wide Open Throttle. Each engine manufacturer will specify the range of RPM that the engine can run at wide open throttle and maximum trim angle. You can find this information in your owner’s manual or on the manufacturers website. It is important to select the correct propeller to run within the WOT RPM range, preferably at higher end of the range.

How do you select the correct pitch for your boat and motor combination? First, you will need to run your boat with your current prop at full throttle and full trim with a normal load. At full throttle, note the RPM on your tachometer. Compare this number to the WOT number for your engine. Also note the pitch of your current prop.

You must have a working tach to determine the correct prop for your boat. If you do not have a tachometer, or believe your tach is not functioning correctly, consult your marine dealer or mechanic to fix the issue before continuing.

Using a propeller that gives you the correct WOT range will give you a better hole shot, better acceleration and better top end. You will get the best performance out of your boat when you are running in the correct RPM range.

Please refer to Selecting the Right Pitch article on how to use WOT RPM information to select the correct pitch of propeller (coming soon 7/2012).
