Yamaha 20 HP Outboard Motor — Electric & Manual Start, Tiller Control

Yamaha’s all-new 20 HP portable outboard is built on the same award-winning platform as the F25, sharing its SOHC in-line design and streamlined intake manifold to deliver solid, dependable power. With a 432cc engine, it offers a strong step up in performance while remaining one of the most fuel-efficient motors in its class.

At just 126 pounds, it’s suitable for lightweight craft such as aluminum fishing boats, tenders, and inflatables, giving you real power without adding unnecessary weight to your boat. Maneuverability is a standout feature, with a 45-degree steering angle in each direction providing excellent control and tight-turning capability — perfect for navigating narrow channels, tricky docking situations, or busy waterways.

Maintenance is simple thanks to a Freshwater Flush Device, which allows you to flush the engine without running it, adding convenience and helping protect your motor after use in saltwater or brackish conditions. With both electric and manual start options, tiller controls, and manual trim & tilt, this motor offers the flexibility and ease of use boaters want in a portable outboard.

Whether you’re upgrading from a smaller motor or looking for reliable power for a lightweight boat, the Yamaha 20 HP delivers the performance, efficiency, and durability Yamaha is known for.

Every unit ships brand new and factory sealed, backed by Yamaha’s full manufacturer warranty for complete peace of mind.
