Manifold – late model (aftermarket) with block off plate, manifold gasket not included.
Original factory manifolds were produced in two different types: Those with exhaust openings only in the reversing gear end and those with openings on both ends. The double-ended manifolds accommodated engines with “V-drives” and other boats which had exhaust systems that exited the vessel other than through the transom.
We made the decision to produce all our aftermarket manifolds in the double-ended style so that they will fit any Atomic 4 engine in the fleet, thereby alleviating any confusion as to what style of manifold would be needed on any particular engine. With a bit of re-plumbing of the cross over tube between the front of the head and the manifold, our aftermarket manifolds will also fit early model engines.
