Suzuki DF9.9BTHXSS 9.9 HP EFI 4-Stroke Stealth Outboard Motor
The Suzuki DF9.9BTHXSS combines Suzuki's proven Electronic Fuel Injection (EFI), electric start, power trim and tilt, and a high-thrust propeller with Suzuki's exclusive Stealth Black finish. Featuring a 25-inch extra long shaft and tiller steering, this premium 9.9 HP outboard is designed for sailboats, auxiliary power applications, heavier displacement boats, and other vessels requiring maximum low-speed thrust and an extra-long-shaft configuration. Suzuki's Stealth lineup features a distinctive matte-style black appearance and is offered in multiple 9.9 HP configurations.
Suzuki's battery-less EFI system delivers dependable starting, excellent fuel economy, smooth throttle response, and reliable performance. The electric-start system provides convenient operation, while the tiller handle offers precise control directly from the stern. Power trim and tilt allows quick adjustment of the engine position for improved performance, shallow-water operation, trailering, and storage.
The included 4-blade high-thrust aluminum propeller provides exceptional low-speed pushing power and improved maneuverability, making the DF9.9BTHXSS especially well suited for sailboats and auxiliary applications where control is more important than top speed.
