Replace your rusty, cracked or just poor performing Mercruiser 4.3L Exhaust Marine Manifold (Part No. 99746A3 and 99746A8) on your Mercruiser Chevrolet Engine with a Direct Replacement Mercruiser 4.3L V-6 Exhaust Manifold, MC-1-99746. Barr has been building quality marine products for nearly 80 years. Manifolds by Barr are covered by a manufacturer's 3-year warranty. It is recommended that replacement manifolds be done in pairs and to also replace the risers and elbows at the same time.

Made in the USA

  • Replaces Merc # 99746A3 and 99746A8
  • Fits Mercruiser 4.3L V-6 Chev engines
  • Includes all mounting hardware, gaskets and plugs
  • Sierra also makes a replacement manifold for (99746A8) MC-1-99746


Peace of mind and power to spare! Barr Manifolds are designed to reduce back-pressure and often when replacing OEM-installed manifolds, more horsepower is achieved.

When choosing a Manifold, it is recommended to also choose the appropriate new risers / elbows. Although Manifolds such as Barr, Osco and others including original equipment often look alike, it is recommended to buy manifolds and risers as sets.
