Mercury 9.9HP Fourstroke Outboard


Mercury’s FourStroke Portables are designed with leading edge features for enhanced reliability and performance. Like trouble-free starting thanks to a fast idle and fuel primer system so the engine runs smoother for longer.

We’ve even added noise-reducing cowls, air intake silencers and through prop exhausts for even cleaner and quieter operation.
