Designed for smooth operation and all-day comfort, the 9.9HP features wide-span motor mounts for reduced vibration and a balanced Multi-function Tiller Handle on select models for effortless control. Its lighting coil, optional 12V alternator, and over-rev/overheat protection make it ideal for both work and leisure.

Compact yet capable, the 9.9HP is perfect for tenders, small fishing boats, or family adventures.
