i damaged my prop blade on my boat in shallow water with a 2003 Johnson 115 hp engine. one blade has a gouge and part of the blade is turned. i guess the prop needs to be replaced. just wondering from others experience what's involved, etc.
If a propeller is only slightly damaged, often a good propeller repair shop can refurbish it. Stainless steel propellers can be easily fixed compared to aluminum ones.
In cases where the blade is very bent or deformed, replace the propeller. Follow the steps in your owners manual, use a new factory cotter pin and torque the prop nut.
