Balance weight detached from the propeller shaft

A detached balance weight may create a sliding, scraping, or ticking type noise during acceleration or deceleration.

  1. Inspect the propeller shaft and tube for a detached balance weight.
  2. Replace components, as required. Do not attempt to reattach the balance weight to the propeller shaft.
