The Mercury 150 Verado redefines expectations
for a 150 Hp outboard through its innovative use of forced induction. By
employing a supercharger with a charge air cooler, the 1.7-liter
inline-four engine produces instant, linear power that translates into
exhilarating acceleration out of the hole and effortless cruising.
This power is delivered with the remarkable smoothness and quiet
operation inherent to the Verado brand, thanks in part to sophisticated
engineering and sound-dampening technology that minimizes noise and
vibration. Fully compatible with Mercury's SmartCraft digital
architecture, it offers features like Digital Throttle and Shift (DTS)
for precise control and can be integrated with joystick piloting for
effortless maneuvering.
Its combination of supercharged performance, lightweight design at 231
kg, and advanced technology makes the Verado 150 a standout choice for
boaters who refuse to compromise on power or refinement.

The supercharged foundation of the Mercury 150 Verado is central to its
performance character.
Cylinder Block: The engine is built on a robust 1.7-liter inline
4-cylinder block. This compact, lightweight foundation is designed
specifically to withstand the demands of a supercharged powerhead.
Cylinder Head and Valvetrain: The engine utilizes a sophisticated Dual
Overhead Cam (DOHC) design with 16 valves. This high-flow valvetrain,
combined with the forced induction system, optimizes cylinder filling to
achieve the engine's 6400 RPM redline and class-leading torque output.
The fuel system is engineered for both high performance and efficiency.
It uses a sequential multi-port electronic fuel injection (EFI) system,
where each cylinder receives a precisely timed and metered fuel charge
for optimal combustion under all loads. The engine's computer manages
this process, integrating with the electronic boost control to deliver a
seamless and responsive power curve.
The engine utilizes an integrated wet sump lubrication system. The
recommended oil is Mercury FourStroke 25W-40 Marine Oil, a formulation
designed to withstand the temperatures present in a supercharged
application. The oil capacity is approximately 6.6 liters (7.0 US
quarts).
Cooling is managed by a high-flow water-cooled system with a thermostat
and pressure control, critical for maintaining safe operating
temperatures. It draws ambient water to cool the powerhead. The system
also serves the charge air cooler (intercooler), which reduces the
temperature of the compressed air from the supercharger before it enters
the combustion chamber, increasing air density and thus power output.
| Mid Section and Lower Unit |
Advanced MidSection (AMS): A signature Verado feature, the AMS cradles
the powerhead on perimeter mounts, moving the engine mounts outward and
aft. This design isolates the powerhead from the transom, drastically
reducing vibration and noise transmitted to the hull and helm for an
exceptionally smooth and quiet ride.
Gearcase and Ratio: The engine is mated to a durable 5.44-inch diameter
gearcase. The gear ratio is a deep 2.08:1, designed to optimize low-end
torque and acceleration. The shift mechanism is forward-neutral-reverse
(F-N-R) with SmartCraft Digital Throttle and Shift (DTS). Exhaust: The
exhaust system is routed through the propeller hub.
The Verado 150 is fitted with a power trim and tilt system with
SmartCraft programmable tilt. This allows for precise adjustment of the
engine angle for optimal boat performance, handling, and shallow water
operation.
Selecting the correct propeller is essential to fully utilize the Verado
150's supercharged torque band. The correct propeller must allow the
engine to operate within its 5800-6400 RPM full-throttle range. The
specific pitch and diameter are determined by factors such as boat
weight, hull design, and intended use, and are best selected using the
Mercury Propeller Selector or dealer expertise. A listing for a Mako 253
Walk Around powered by twin Verado 150s showed stainless steel, 3-blade
propellers.
Shaft Length Options:
20 inches (508 mm).
25 inches (635 mm).
30 inches (762 mm).

The supercharged Verado 150 is a versatile powerhouse, ideal for a wide
range of demanding applications where performance and refinement are
valued. Recreational Boating: Perfect for powering family runabouts,
deck boats, and pontoons, providing the torque for watersports and the
quiet operation for comfortable cruising.
Fishing Boats: An excellent choice for bay boats, center consoles, and
walk-arounds, delivering the hole shot to reach fishing spots quickly
and the smoothness desired by anglers. Commercial Use: Suitable for
light-duty commercial applications such as tour boats and small
workboats due to its durability and reliability.
