A misaligned or damaged propeller can have a major effect on your boat’s performance and fuel economy, so inspect yours for signs of damage before the boating season starts. Also, consider keeping a spare prop onboard in case your main one suffers damage on the water. It could be your ticket back to the ramp or dock.
