32-14358T Lower 4-Inch Exhaust Bellows 2-Pack · Fits MerCruiser V6/V8 center-rise 4-inch elbow to Y-pipe, Replaces 18-2746, 89130, 9-72811

GHMarine lower 4-inch exhaust bellows 2-pack — two identical 32-14358T lower boots for the engine-bay center-rise wet exhaust path between the 4-inch exhaust elbow and 4-inch Y-pipe. This is a GHMarine internal 2-pack — there is no Mercury parent kit number. It is not a factory transom seal kit and not an upper + lower combo.

Confirmed contents: 2 × lower 32-14358T bellows. Clamps may appear with individual boots in photos — confirm clamp count against your package before install; do not assume a fixed clamp BOM from this page alone.

Which bellow is this?

Each piece is the lower 4-inch rubber exhaust connector (elbow to Y-pipe) on select MerCruiser V6/V8 center-rise wet-exhaust layouts. This box simply gives you two of the same lower boot.

It is not the upper 4-inch boot (32-44348T — see single SKU 17B1002 / kits with upper), not a 3-inch lower (32-90949T), not a U-joint bellow (816431A1), and not a twin-engine upper+lower+shutter kit (GH 18BS002).

Signs yours is due

• Only the lower elbow→Y-pipe joint is bad (or you want two spare lowers) — upper 32-44348T is still good or stocked separately.
• Water / soot at the lower 4-inch joint after a blocked impeller cooked the rubber hard and shiny — replace the lower boot(s), not a shutter kit.
• Twin banks or a spare: you need two identical 32-14358T lowers in one box (this SKU), not an upper+lower combo.
• Divert: need upper+lower on one engine → GH 18BS001. Twin engines with shutters → GH 18BS002. Single lower only → GH 17B1001.

Will it fit my drive?

This 2-pack is Compatible with select MerCruiser V6/V8 center-rise wet-exhaust applications that use the 32-14358T lower 4-inch boot (4-inch elbow to 4-inch Y-pipe). Catalog starting band is about 1987 & up — years alone do not prove fit. Confirm original hose number, lower position, engine/exhaust assembly, and serial.

*Catalog representative start year. Final fit = original lower part number + 4-inch lower position + engine/exhaust SN — not horsepower alone.

Install tips in the engine bay

Engine-bay wet-exhaust connector work — not a sterndrive bell-housing bellow job. If you are not comfortable opening the 4-inch wet-exhaust path, use a marine shop. Do NOT copy pull-drive / bellows-adhesive / expander steps from a transom boot listing.

1. Confirm each boot is 32-14358T lower 4-inch (elbow to Y-pipe) — not upper 32-44348T.
2. Support the joint; loosen clamps; remove the old lower boot; clean mating surfaces.
3. Align the oval / round interfaces; seat the new boot fully without twist or kink.
4. Install clamps if supplied in your package; tighten to the service-manual specification.
5. Run and check for water / exhaust leaks and normal temperature before returning the boat to service. Repeat for the second boot if servicing both banks / keeping a spare.

FAQ

Is this an OEM Mercury kit number?

No. 18BK001 is a GHMarine internal 2-pack of the same OEM lower bellow 32-14358T. There is no Mercury parent kit number for this double pack.

Is this the same as 17B1001?

Same lower part family (32-14358T). 17B1001 is the single. This listing is a 2-pack of that same lower boot.

Does this include the upper bellow or shutters?

No. Lower 32-14358T only ×2. Upper is 32-44348T. For upper+lower or twin-engine packs, see GH 18BS001 / 18BS002.

Is this a transom seal kit?

No. This is an engine-bay lower wet-exhaust connector. It does not include gimbal bearing, shift bellow, or U-joint bellow.

How many clamps are included?

This page locks only 2 × bellows. Clamp count is not a fixed outbound BOM here — check your package photo / packing slip.

Do I need bellows adhesive or an expander?

Follow the service method for this lower connector joint. Do not blindly copy adhesive / expander / pull-drive steps from a transom bell-housing bellow listing (GH 17B1003).
