To replace a windshield on a boat, detach the old windshield by removing the corresponding screw caps and screws, and place the new windshield in the correct position. Using grommets that come with the replacement windshield and screws, secure the new windshield. Replace the screw caps.
To detach the old windshield on a boat, first pry out the windshield's plastic screw caps using a screwdriver with a flat head. Screws that secure the windshield to the boat are located beneath the screw caps. Undo these screws using a screwdriver.
Keep the screw caps and the screws safely aside in two separate containers, as they are required for attaching the replacement windshield.
Then, gently pull the old windshield upward to lift it off the boat. Position the replacement windshield in the same location as the old one. Ensure that the holes for the screws located on the bottom edge of the new windshield are aligned with the screw holes on the boat.
Position a grommet on each of the screws, insert the screws into the aligned holes, and tighten them using a screwdriver. Ensure that the screws are tightened in a straight direction, as screws that are inserted crookedly can damage the windshield. Finally, press the screw caps into position over all of the screws.
