I need a gear set for a upper drive. Mercury used to sell a kit that had the
drive shaft, clutch and shift yoke with the gears. Anyone know what high
bump means? The old set is or was 23 pinion and 30 driven.
Thank you. I believe S# is of to om.

What is the difference between high bump and low bump gears?

Low Bump is for a standard Bravo Drive.
High Bump is in X and XR Bravo Drives

How can you tell by looking at the gears?

How the hell can you tell what you have, x or xr high bump or low bump?
No one knows?

The actual case number will determine what drive you have, I have never laid the two sets of gears side by side to see what the difference is.

When I repair a drive I pull the serial number off the case and order accordingly. Maybe this will help.
