Yamaha F150 Jet Drive | F150JC

The Yamaha F150 Jet Drive (F150JC) completely redefines where an outboard motor can go by replacing a traditional lower unit gearcase with an advanced hydrodynamic jet pump system. Built on Yamaha’s legendary 2.7-liter, double-overhead-cam (DOHC) four-cylinder platform, this engine is optimized to handle thin water, rocky riverbeds, and hidden sandbars where a standard propeller would quickly meet disaster. Because jet pumps experience a natural 30% parasitic power loss compared to props, this 150HP powerhead is masterfully calibrated to deliver a highly effective 105 horsepower at the pump nozzle.

Without a protruding lower unit or skeg, the F150JC draws water through an intake grate and forcefully ejects it through a directional nozzle, allowing high-performance aluminum and fiberglass hulls to skim across just inches of water. The engine utilizes an integrated twin-counterbalancer system to virtually eliminate vibration, making it incredibly smooth at cruising speeds. Equipped with Electronic Fuel Injection (EFI) and a microcomputer Engine Control Module (ECM), it provides responsive acceleration, instant starts, and the bulletproof reliability needed when navigating isolated, shallow-water rapids.

Models Available:

• F150JC:Jet drive configuration built on the 2.7L DOHC four-stroke powerhead. Features a specialized short midsection to match jet-transom heights, electric starting, and standard remote mechanical control integration.

Key Features:

• Powerhead Displacement: 2670cc (2.7L) inline-4 four-stroke (DOHC)

• Output Rating: 150 HP at the crankshaft / 105 HP at the jet pump nozzle

• Propulsion System: Outboard Jet Pump (No propeller, completely flush intake shoe)

• Control Type: Remote Mechanical (Traditional throttle/shift cables adjusting the jet gate)

• Fuel system: Electronic Fuel Injection (EFI)

• Alternator Output: 35 Amps (Substantial power supply for running shallow-water anchors, light bars, and electronics)

• Weight: approx. 217 kg (478 lbs)

• Shift Dampener System eliminated due to direct-drive impeller layout

• Advanced Phaze Five™ multi-layer anti-corrosive paint barrier

Ideal For: Aluminum river jet boats, shallow-water flats skiffs, rocky rapid navigation, snake-river style hulls, and shallow-draft utility platforms.
