Affordable, dependable, and lightweight, checks all the boxes. Perfect for lake runs and trolling, plus it sips fuel compared to others I’ve used.

Got the 2020 Mercury 9.9HP for my dinghy, and it’s been fantastic. Smooth throttle response, easy to service, and it pushes my boat just right without burning through fuel. Solid engine.
