The Flow Max Scupper only comes with one screw. The screws that screw it to the boat do not come with it. They will be different for every boat depending on the hull thickness but you will need a flat head screw. Screw included is a #4 x 1/4" Phillips Pan Head Stainless Steel Screw.
Upgrade your boat's drainage system with the T-H Marine Supplies Flow-Max Ball Scupper in clear finish. Designed for reliable performance, this positive sealing ball scupper features a larger exit hole that allows for 70% more water drainage compared to standard models, helping to keep your deck dry and safe. Its multiple mounting holes enable quick and easy retrofitting without the need for filling or re-drilling, making installation straightforward and hassle-free. The neutral buoyancy of the ball prevents it from floating up and breaking the seal, ensuring consistent operation in various conditions. Crafted to meet all ABYC standards, the Flow-Max scupper provides a durable and dependable solution for marine drainage needs. The twist-off design simplifies maintenance—just twist counterclockwise to remove the ball cavity, clean debris, and reassemble effortlessly. A stainless steel security pin adds extra safety, ensuring the cap stays securely in place during operation. This model is compatible with slotted seals designed to fit over 1-1/4-inch motor well tubes, making it suitable for a wide range of vessel configurations. Please note that the package includes only one screw; mounting screws are not included because they vary depending on hull thickness. The included screw is a #4 x 1/4-inch Phillips pan head stainless steel screw, but installation may require different fasteners based on your boat's specifications. Whether replacing worn-out flapper scuppers or upgrading to a high-performance drainage system, the Flow-Max Ball Scupper offers a reliable, easy-to-maintain solution to improve your vessel's drainage efficiency and overall safety.

The Trident Marin Extra Flex Corrugated Wet Exhaust hose works great. I had to replace the old hose coming from the generator muffler to the exhaust pipe going out the hull. The hose needed to be curved and the flex was perfect. Delivery was fast with no issues. Thank you
