Yamaha 2017 Yamaha F20 SMHA Outboard Motor

Trim code SMHA shaves Yamaha's 2017 F20 down to 111 lbs dry, lighter than its SEHA counterpart, while keeping the same 15-inch shaft and 362cc two-cylinder four-stroke underneath. For a buyer counting every pound on a small boat, that weight is the detail worth knowing. Fit and rigging Confirm the 15-inch shaft against your transom height first, since swapping a shaft after delivery usually means a return rather than a quick fix. Tilt spans 67 to 71 degrees across four settings, steering swings 45 degrees each way, and starting is offered manual or electric, so match that to your rigging before you order. Power and feed Compression sits at 9.3:1 on a 2.08:1 gear ratio, with Yamaha calling for regular unleaded at a minimum of 87 octane. The alternator delivers 10 amps, oil capacity is 1.8 liters once a filter goes in, 1.6 liters bare, and the motor is rated to a three-star emissions standard. Common questions How does this differ from the SEHA version? Both share the engine, shaft, and controls; this trim's dry weight comes in a few pounds lighter, which can matter on a boat near its max-rated transom load. What's covered under warranty? Three years applies to pleasure use (two of those on the jet pump assembly where fitted), three years to government use, one year to commercial use.
