| MerCruiser V6 262 4.3L Chevy Marine Exhaust Manifolds 1983-2001 |
The Moore Performance manifolds are an exact replacement for
the MerCruiser V6 manifolds. The external dimensions are
identical with all holes drilled and tapped like the original
manifolds.

The aluminum manifolds come with
anodes that can be installed inside
the manifolds water jacket to
prevent corrosion. The cast iron
manifolds have provisions for
installing the anodes as well.

The manifolds come with new water
inlet elbows that have drain plugs
for quick winterizing.

Each manifold comes with a new gasket. This is the best gasket on the
market. It is a sandwich style gasket consisting of a metal core with
graphite gasket material on both sides. The metal core keeps the gasket
from blowing out under pressure. Never use a cheap paper gasket that
is simply stamped out of exhaust gasket material!

Every manifold comes with a stainless steel "sandwich style" riser gasket.
This is the "restricted" gasket used with most Mercruiser cooling systems.

All of the external dimensions of the
Moore Performance manifolds are
identical however the inside of the
manifolds are quite different than the
stock MerCruiser manifolds. Dividers
have been placed inside the manifold
plenum. These dividers separate the
exhaust pulses from each cylinder and
guide the exhaust gases towards the
outlet. The effect of the dividers results
in an increase in performance and fuel
economy. The original MerCruiser
manifolds have no dividers only an open
plenum.
