DO NOT misinterpret propeller shaft movement with propeller movement. If pro-
peller and propeller shaft together move forward-and-aft, this is normal; how-
ever, propeller should not move forward-and-aft on propeller shaft.
9. After first use, retighten propeller nut and again secure with tab washer (Steps 7 and
8, preceding). Propeller should be checked periodically for tightness, particularly if a
stainless steel propeller is used.
