How to identify the drive
Decal on the port or starboard side of the upper drive shaft housing. On newer Bravo drives the number may be stamped behind the rear cover. The transom assembly has its own number on the inner or outer plate. Confirm the gear ratio from the markings or a serial-number-specific parts catalog.
