Remove TW

The stock thrustwasher prevents the propeller from contacting your gearcase and allows the prop to turn freely without binding. Some Piranha propeller hubs have the thrustwasher built in. Failure to remove your original thrustwasher in these cases causes the propeller to be “double spaced” and you will consequently have less prop shaft sticking through the prop. This might make it tough to get the prop nut tightened. Also, this can cause exhaust to leak between the prop and the gearcase, causing the prop to slip excessively.
