Boat motors are complex and require many parts that work together to keep your boat moving through the water. One of those parts is a marine manifold that’s responsible for supplying the fuel and air mixture to the cylinders. When your boat engine manifold or exhaust manifold gives out, Overton’s has replacements available to get you back on the water. A faulty exhaust manifold for your boat engine or a non-working intake manifold can mean less time on the water – and no one wants that. Stock up on replacements today. Use our Marine Engine Parts Selector Tool to find the right engine parts for your boat.
