2017 Yamaha F15 LPHA Outboard Motor

Heaviest of the three 20-inch-shaft F15 trims covered here, this LPHA lists a dry weight of 132 lbs, running the same 362cc two-cylinder four-stroke, fed by a single carburetor with CDI timing, as its LEHA and LMHA relatives, with manual or electric starting offered.

Sizing and running figures

Plan carry handles and transom rating around 132 lbs, since that's noticeably more than its lighter siblings on the same 20-inch shaft. Steering reaches 45 degrees off center in both directions, the powerhead runs 9.3:1 compression, gearing comes in at 2.08:1 across forward-neutral-reverse, and the tilt bracket offers four stops between 67 and 71 degrees, with oil capacity set at 1.8 liters filtered or 1.6 unfiltered.

The extra weight next to its siblings comes from running the same core engine, so it is not a sign of a different displacement or cylinder count, just trim-level hardware differences Yamaha does not break out in detail.

Questions buyers ask

Carbureted or fuel injected? Carbureted, with CDI microcomputer ignition handling timing.

What fuel does it run on? Regular unleaded, minimum 87 octane.

Is there a warranty? Coverage here runs 3 years for pleasure boat use and 1 year for commercial use, under Yamaha's limited terms.

Does it need a battery to start? No, manual start is available alongside electric.

Will any F15 propeller fit it? Match the propeller to the shaft and gear ratio rather than assuming interchangeability across trims; confirm fitment with us if ordering a prop separately.
