When you are checking your boat over before heading out, don’t overlook the propeller. Check the propeller as part of your pre-launch routine. Use a deep well socket to remove the propeller several times during the season to make sure discarded fishing line hasn't become wrapped around the propeller shaft. While you have the propeller off, inspect it for nicks, dents and other signs of damage. The smallest dent can cause your boat to lose performance and burn excessive fuel.
