DRIVE SYSTEMS EXHAUST MANIFOLDS

FIND THE APPROPRIATE LISTING FOR YOUR MOTOR BELOW.

  NOTE!! You MUST PROVIDE THE ENGINE SERIAL NUMBER when ordering.
We cannot send you the correct parts otherwise!

Note: due to weight, manifolds and risers will incur an additional shipping charge, which will be what it actually costs us to get it to you. Estimated shipping is included in price. If shipping is substantially more, we will notify you.

The various manufacturers are always changing availability and prices on Mercruiser manifolds (including Mercury Marine). We list here a selection of manifolds and risers from Sierra. There are some available not listed here, and in many cases there are other brands we can also get in place of Sierra. If yours is not listed here or if you have other questions, please CONTACT us and we'll see what we can do to help.
