Performance & Practical Benefits

The parts in this kit work together to keep your Bravo Two feeling strong, steady, and trustworthy. Fresh gaskets and seals help the gearcase stay tight and dry. New anodes protect the drive from corrosion, especially if you boat in saltwater or mixed-salinity areas. The shift cable kit brings back crisp shifting, something you notice instantly the next time you throttle out of the no-wake zone.

You’ll feel the difference on the water. Gear changes become smoother. Engine response feels more settled, without the hesitation that worn parts can create. The drive runs quieter and more controlled, especially during long cruising days or when you’re moving weight around the boat. With everything installed at once, the whole system works in harmony—no mismatched components, no wondering if the last owner or mechanic forgot a key part.

Maintenance becomes simpler and more predictable. Instead of tracking down separate gaskets or trying to match hardware, you’ve got everything ready in one kit. Pair this service with Mercury Four-Stroke Marine Engine Oil and Mercury Premium Gear Lube (sold separately), and your drive is set up for another reliable season.

Why Buy OEM

When you’re dealing with a sterndrive, fitment matters. Aftermarket parts might look close, but even tiny differences can lead to leaks, poor sealing, or premature wear. An OEM Mercury Marine part fits correctly the first time and is made from materials tested for real boating conditions. The added durability protects your investment and saves time, money, and frustration in the long run. When it comes to Bravo Two maintenance, OEM is simply the smarter choice.
