SeaSierra Transom Bellow Kit for Mercruiser Bravo 8M0095485 — OEM-quality complete kit with gimbal bearing and hoses

SeaSierra 8M0095485 Transom Bellow Kit is a complete OEM-quality seal and bellows repair kit designed to restore the transom seal system on Mercruiser Bravo 1, 2, 3, Bravo X and Blackhawk stern drives.

When a stern drive starts showing water intrusion, grease leakage, or worn bellows, replacing the transom seal assembly with a full kit reduces downtime and prevents further damage. This SeaSierra kit brings together bellows, gimbal bearing, seals and hoses that match OEM part numbers so you can service the entire transom interface in one job.

What parts are included and why do they matter?

The kit bundles the main bellows, exhaust bellows, shift cable bellow, gimbal bearing, drive seal kit and associated hoses and tubing so all aging components are replaced at once. Replacing only one piece can leave adjacent parts to fail soon after.

• U-joint bellow 86840A3 — protects universal joint from water and contaminants
• Exhaust bellow 78458A1 — isolates exhaust passages and prevents leaks
• Shift cable bellow 74639 — seals the shift linkage at the transom
• Gimbal bearing 30-60792A4 — greasable bearing for smoother drive alignment
• Drive Seal Kit 16755T1 and water hose 32-43437 — replace worn seals and delivery lines

Which Mercruiser models and OEM numbers does this fit?

This SeaSierra kit is engineered to fit Mercruiser Bravo Series stern drives and compatible variants. Confirm your drive model and serial before purchase to ensure correct fitment.

How does this kit simplify a transom seal repair?

By supplying every critical sealing component and the gimbal bearing, the kit removes the need to hunt for individual parts. That saves time and ensures mating surfaces and passages are sealed correctly during reassembly.

• Greasable bearing aids future maintenance and longevity
• Includes hoses and tubes needed to restore water and exhaust connections

What should I check before buying and installing?

Verify your stern drive model, inspect the transom housing and mounting hardware for damage, and ensure you have basic mechanical tools and marine-grade lubricants. Professional installation is recommended if you lack stern drive experience.

• Confirm drive model and serial against kit cross-references
• Inspect transom and bellhousing for corrosion or cracks before replacement
• Have grease, sealant and torque specs ready for reassembly
