Yamaha 20 HP Outboard Motors

We have 2 Yamaha 20 HP models in stock, starting at $4,195. Shaft lengths available: 15" and 20". Starting: manual start and electric start. Steering: tiller.

20 HP outboard motors are one of the most popular horsepower classes on the market — powerful enough for 16–18 foot fishing boats and jon boats, yet still portable enough to carry without a crane. This class is available from all major manufacturers including Yamaha, Honda, Mercury, and Tohatsu, giving buyers a wide choice of tiller or remote control, manual or electric start, and short or long shaft configurations. Four-stroke 20 HP motors run clean, quiet, and efficiently — making them ideal for lakes, rivers, and inshore coastal use. Every portable Yamaha motor ships free to the lower 48 states from Clay Powersports, an authorized Yamaha dealer.
