Product Description

IN-LINE 4 **0 hp

The lightest DOHC outboard in its class, this I*4 is the perfect, lightweight ***-hp solution for small- to medium-size boats. Plus, its the first in-line four compatible with Helm Master®, our fully integrated digital boat control system.

Compatible with mechanical controls or digital Command Link Plus® or Helm Master® controls
Runs on economical *9 octane
Only **7 pounds (*0 shaft model)
*0 or *5 shaft options (LH rotation available in *5 shaft digital control)
**-amp alternator provides *3 percent more power than V6 3.*-liter F**0

IMPRESSIVE POWER-TO-WEIGHT

A proven **-valve DOHC In-Line design, with four valves per cylinder maximizes efficiency and power. It also streamlines design, giving the F**0 class-leading power-to-weight and making the F**5 nearly *0 pounds lighter than its closest 1.*-liter competitor.

OPTIMUM POWER

Precision Multi-Point Electronic Fuel Injection and long-track intake system combine to maximize power and fuel efficiency across the line of In-Line Fours (except F**0 Mechanical).

TWO-STROKE PERFORMANCE FROM A FOUR STROKE

Four valves per cylinder maximizes combustion efficiency in a way that no two stroke can, delivering the utmost in clean, quiet power and performance.

QUICK ACCELERATION

A *0mm Offset Crankshaft allows for larger intake volume design. Four tuned intake tubes boost torque in low and mid-speed ranges for quick acceleration.

POWERFUL HOLE SHOT

The Composite Intake Manifold is a lightweight, compact design, making these engines very versatile. Long Tube Intake Tracks are tuned to increase airflow, boosting low-end and midrange torque. This means a more powerful hole shot and increased acceleration. Even with all this responsive power, an air silencer box and surge tank reduce air intake noise and air turbulence for smoother operation.

INCREDIBLE LOW AND MID-RANGE TORQUE

Variable Camshaft Timing (VCT), available on F**5 and F**0, advances or slows the camshaft timing based on engine load and RPM, improving intake and exhaust efficiency and boosting torque in the 2,**0 to 3,**0 RPM range
