Mercury 150 HP SeaPro Counter-Rotation Complete Gearcase 8M0099914

Mercury Complete Gearcase 8M0099914 is an OEM replacement lower unit designed for select Mercury 150 HP EFI SeaPro FourStroke outboards. This SeaPro-specific assembly is the counter-rotation (CXL) 25-inch configuration.

Compatible with select applications including:

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

Mercury parts diagrams list 8M0099914 specifically as the complete CXL SeaPro gear housing assembly. It includes the internal gearcase components rather than being an empty housing. The corresponding basic SeaPro gear housing is 8M0099907.

This gearcase is distinct from the standard-rotation SeaPro versions and from the non-SeaPro CXL gearcase. For example, 8M0107156 is the corresponding complete CXL gearcase listed for non-SeaPro applications, so the SeaPro designation is important when confirming fitment.
