Review on 🚰 Pair of Sierra 18-2732-9 Water Shutters (Set of 2) for Mercruiser 807166A3 (1982-1996) Replacement by Anthony Arcos

Skip them and spend more on OEM. Low quality.

Pulled my downforce with less than 10 hours on these exhaust flaps to find a half of it in the tailpipe. The rubber is torn in two. Always worked with good water flow and without overheating during these 10 hours. Spend extra money on OEM this time.

Pros
