Yamaha In-Line Four · Virginia Beach
Yamaha F150 Power-Assisted Tiller outboard: specs, rigging and repower in Virginia Beach.
The F150XHA is the 150 hp In-Line Four built as a power-assisted tiller: hydraulic assist on the tiller handle, a 25-inch shaft and 566 lb. It is a 2.8-liter engine with a 50-amp alternator, and Yamaha lists no remote controls for it, so the tiller is the helm.
