6 reviews for Yamaha 20hp 20″ Shaft | F20LWHB
Perfect outboard for my 16′ aluminum skiff in Florida. The price was really good for a Yamaha motor with this performance. It’s light, easy to mount, and super dependable on the water.
Running this on my 19′ pontoon in Seattle. The 20″ shaft provides enough clearance, and the motor starts easily even in cold mornings. Very satisfied with the smooth power delivery.
Installed on my 15′ fishing boat in Chesapeake Bay. Runs quietly and handles well in shallow water. Only small complaint is the weight—it’s a bit heavier than I expected.
Great motor for the price and performance. Using it on my 18′ center console in Gulf Shores, AL. Reliable, fuel-efficient, and easy to maintain. Would definitely buy again.
Installed this Yamaha on my 17′ jon boat on the Mississippi River. Starts up easily every time and runs smoothly. Great power for small boats, and the 20″ shaft is perfect for my setup.
