Boat Thru Hull Exhaust Fittings

Marine Parts Source is where to find thru hull exhaust parts from leading brands like Buck Algonquin, Corsa Performance, Vetus and Centek. Running the exhaust through the hull allows the engine to run cooler and increases exhaust flow, giving a small but noticeable horsepower boost. These fittings are the most essential part of a thru-hull exhaust kit as they connect to the pipe so the exhaust gases can escape. You can have a boat thru hull exhaust exiting above the water for a big, head-turning sound or below the water for a quieter ride with fewer fumes.

We offer an assortment of side and transoms thru hull boat exhaust fittings in different sizes. They’re made of rust- and heat-resistant materials like fiberglass and stainless steel for lasting excellence. A thru hull exhaust fitting with a flapper valve is a must for underwater exits to help prevent backflow. Order high-quality marine exhaust parts that ship the same business day when they’re in stock.
