45-degree water bypass fittings increase engine performance by diverting water from the cylinder head to the bypass fitting, rather than forcing all of the water thru the exhaust system, thus drying out the exhaust. These machined bypass fittings are angled at 45 degrees and fit a 1/2" id waterline and 3/4 inch hole thru the hull. Anodized for protection against corrosion. Can be used to replace the stock water bypass or to add additional bypasses for added cooling. Fits many PWC models such as Sea-Doo, Kawasaki, Yamaha, Polaris, and Honda. Also fits the Yamaha AR series boats with the TR-1 and 1.8L engines.
