Exhaust and intake parts shown in this diagram

The drawing identifies exhaust manifold, exhaust elbow, gasket and transom for MerCruiser 4.3L carburettor and MPI Alpha / Bravo. Use the callout and schedule together so the manifold, elbow, joint and sealing parts stay tied to the correct assembly.

Select exhaust and intake parts by assembly

Treat manifolds, elbows, connecting hardware and sealing joints as one matched assembly route. Confirm the engine configuration and the numbered position before choosing an individual component.

Manifolds, elbows and connecting parts

Confirm the engine configuration and the exact joint arrangement before selecting a manifold or elbow. Similar castings can use different heights, angles, water passages or connecting hardware.

Gaskets and sealing joints

Match each gasket to the faces and numbered position shown. A gasket that shares an engine family is not automatically correct for every manifold, riser or elbow configuration.

How to use the diagram and parts schedule

  1. Confirm that the equipment is MerCruiser 4.3L carburettor and MPI Alpha / Bravo and check any page-level year or serial scope.
  2. Find the required component on the exploded drawing and note its numbered callout.
  3. Match the callout to the product code and OEM cross-reference in the parts schedule.
  4. Apply every model, serial, ratio, side, material and configuration note shown for that row.
  5. Compare the selected replacement with the removed part before installation.

Fitment and cross-reference checks

The page-level route is MerCruiser 4.3L carburettor and MPI Alpha / Bravo. It helps customers reach the correct drawing, but it does not make every product in the schedule interchangeable across every version of that model family.

An OEM number is an identification cross-reference. Confirm the exact product code, model designation and any bounded selection information before ordering. A product may also appear under another make or model only where that separate SKU-to-application fitment is independently supported.

Which parts are shown on this MerCruiser 4.3L CARB MPI ALPHA / BRAVO diagram?

This MerCruiser 4.3L CARB MPI ALPHA / BRAVO page covers exhaust manifold, exhaust elbow, gasket, transom within the exhaust and intake parts drawing. Use the callout position to identify the required assembly before choosing a product.

Does this diagram confirm fitment for every MerCruiser 4.3L CARB MPI ALPHA / BRAVO version?

No. This exhaust and intake parts diagram establishes the MerCruiser 4.3L CARB MPI ALPHA / BRAVO page application, but it does not make every scheduled product interchangeable across every version. No page-level year or serial boundary is printed. Confirm the exact model and then apply any year, serial, ratio or configuration note shown on the selected schedule row.

How should I use the diagram number and OEM cross-reference?

Find the exhaust and intake parts part on the MerCruiser 4.3L CARB MPI ALPHA / BRAVO drawing, match its callout to the schedule, then confirm the supplier reference and OEM cross-reference. The OEM number helps identify the part, but the selected row's application notes still control fitment.

Can a similar-looking manifold, elbow, riser or gasket be substituted?

Not for MerCruiser 4.3L CARB MPI ALPHA / BRAVO without matching the exact reference and joint arrangement. Height, angle, water passages, wet or dry joint design and production changes can make visually similar exhaust parts incompatible.

What information should I provide if I need help identifying a part?

Provide the full MerCruiser 4.3L CARB MPI ALPHA / BRAVO model, serial number where available, the exhaust and intake parts diagram callout, the printed product or OEM reference and a clear photo of the removed part or identification plate.
