F20SMHB Yamaha 4 Stroke 20hp Short Shaft, Manual Start, Mechanical Trim & Tilt System, Battery-Less Electronic Fuel Injection, Tiller Handle PORTABLE OUTBOARD FOR SALE

The new F20 is built around the award winning F25, an Innovation Award-winning outboard that immediately set the industry standard. Modified ECU mapping and a redesigned camshaft allows the new F20 to harness the huge potential of this outboard and to optimize its performance.
The result is an exceptionally strong outboard with the versatility to power a wide variety of boats.

The new F20 delivers fast acceleration and enhanced boat performance under load, so when it’s time to hit the water, you won’t have to leave anything (or anyone) behind. The variable trolling rpm switch makes the F20 the perfect fishing companion, while the easy to use fresh water flush attachment makes the engine a breeze to clean at the end of the day. Built-in ergonomic carry handles and two-position resting pads make it easy to remove and store the F20.

Customers can choose manual start configuration, using Yamaha’s battery-less EFI technology, to power their boat with minimum rigging

Yamaha offers a range of electric-start configurations, all with the added peace of mind of factory installed manual pull start.
