Mercury 150 HP SeaPro XL Complete Gearcase 8M0099910

Mercury Complete Gearcase 8M0099910 is an OEM replacement lower unit designed for select Mercury 150 HP EFI SeaPro FourStroke outboards. This SeaPro-specific gearcase is the standard-rotation XL configuration for compatible 25-inch shaft engines.

Compatible with select applications including:

• Mercury 150 HP EFI SeaPro FourStroke
• Standard-rotation SeaPro configurations
• 25-inch shaft applications

Mercury identifies 8M0099910 as the complete G/C XL 150HP SEA assembly. This is a complete gearcase, rather than an empty gear housing, and includes the internal gearing and related lower-unit components for the applicable configuration.

It is important to distinguish this gearcase from 8M0099914, which is the corresponding counter-rotation CXL SeaPro gearcase. Engine configuration and rotation should be confirmed before ordering, particularly on multi-engine installations.
