The flappers were too big, stick with Sierra, you can’t go wrong…

Visually the water shutters look the same as the updated ones from Mercury but they are about 1/16th off from the tabs fitting in the holes to keep them in place. After fighting these and modifying them for a few hours I went to the local Marine and bought genuine ones that snapped right in place. The boots worked fine and quality seems like it will hold up. As others have said toss the clamps that come with this kit and re-use the old ones or just skip this kit all together to save the headache.

Shipped quickly and well packed. The hose clamps were barely long enough, so ended up reusing the old ones to simplify installation.

Parts went together fairly easy, but the hose clamps that came with the set are a bit on the weak side.
