• Propeller
• Engine mounting height
• Gear ratio
• Number of engines
• Fuel and passenger load
• Water conditions

A properly matched propeller and correctly installed engine are essential to achieving the expected performance.

2.6-Liter Verado Powerhead

The 2019 350HP Verado generation represented by the 2.6L specification uses a 2.6-liter inline-six powerhead.

The inline-six layout is designed to provide smooth power delivery while the relatively compact displacement is supported by forced induction to produce the engine’s high horsepower rating.

The 350HP version uses a supercharged induction system with charge-air cooling, allowing the engine to move a greater mass of air through the combustion system than a naturally aspirated engine of similar displacement.

Supercharged Performance

Supercharging is one of the defining characteristics of the 2.6L high-output Verado platform.

The system helps produce:

• Strong acceleration
• High specific power output
• Strong mid-range torque
• Responsive throttle behavior
• High-RPM performance
• Consistent power delivery under load

The charge-air cooling system helps manage intake-air temperatures and supports the engine’s performance under demanding operating conditions.

Because the engine uses forced induction, regular maintenance and correct lubrication are particularly important.

Electronic Fuel Injection

Unlike a traditional mechanical throttle and shift cable system, electronic control allows throttle and gear-shift commands to be managed electronically.

DTS can provide:

• Smooth gear engagement
• Precise throttle response
• Reduced cable friction
• Integrated digital engine control
• Compatibility with SmartCraft systems
• Improved control in docking and maneuvering situations

The exact rigging components should be verified when using this engine in a repower because Mercury digital systems require compatible controls and instrumentation.

Advanced MidSection

The Verado platform incorporates Advanced MidSection technology designed to isolate engine vibration from the boat.

This contributes to the refined character associated with Verado outboards by helping reduce vibration transferred through the transom.

For larger recreational and offshore boats, reduced vibration can be particularly beneficial during extended cruising.

150-Amp Alternator

One of the notable specifications of this engine is its 150-amp alternator.

The substantial electrical output can support boats equipped with significant onboard electrical loads.

Potential electrical equipment may include:

• Marine navigation systems
• Chartplotters

Actual charging capability depends on engine speed and the boat’s electrical configuration.

Shaft Length

The product listing specifies 20-inch and 25-inch shaft configurations.

Selecting the correct shaft length is critical when installing a 350HP outboard.

The correct configuration depends on the boat’s:

• Transom height
• Hull design
• Engine mounting position
• Manufacturer specifications
• Number of engines
• Intended operating conditions

For a repower, measure the existing installation and confirm the boat manufacturer’s recommended shaft length rather than selecting based solely on the existing engine.
