M8

Drive

The M8 drive features robust internal drive components. This surface-piercing gearcase is compliments a lower engine profile. Lowering engine mounting in a boat results in a lower center of gravity for improved boat handling and overall performance; it also provides more flexibility in boat hatch styling. Like the M6, the M8 is dry-sumped for maximum efficiency and power output.
