A buddy took my glastron out to one of the area lakes and as he was backing down an unfamiliar ramp he snagged the skeg on a poorly repaired hole ( Skeg to ramp = 3 in., concrete bump, 4 in high) He said the boat runs like a scalded ape and didn't notice the bent skeg until after he pulled out of the water. It has a nice curve to the right. Can it be/how do I straighten it?
