I have a 226 with that deflector and it has a crack around the mounting screw. I’ve been thinking of removing it but I have the same questions. There had to be a good reason for Grady to go to the expense of installing them.
I've got an aftermarket top with Ebox. If I don't have the front curtain on I get blasted from wind off the ebox. Would like to see what the deflector looks like.
Mine has the same but it doesn’t do much for me to the point that I wear protective glasses when it’s dark out because of the wind. Use a cheap pair from Amazon.
This boat was not designed for a 6ft person....when sitting the top metal piece on the window blocks my vision and when standing the wind is in my face
