David, does your accessory catalog mention these exhaust cutout’s. I have been told by some that you could buy the motors with these installed. Did some motors just come with them? Would like some documentation to know if that was really the case. Are they really a Johnson part, or aftermarket item? Were they sold at the dealership? Would a dealer install them, or were they DIY.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
