Mercury Racing Releases New Pro Max 225X Outboard
Fond du Lac, WI - Mercury Racing is pleased to announce the release of the
all-new Mercury Pro Max 225X consumer performance outboard. The highly
anticipated engine features the latest marine propulsion technology available
from Mercury Racing.
The 225X leads the 225 horsepower outboard engine class with unmatched
power and performance. The powerhead is all-new, from the 2.5 Liter V-6 cylinder
block to the PCM 555 SmartCraftTM CAN electronic control system.
Production begins with a stock Mercury 2.5 Liter 200 EFI V-6 cylinder
block. High performance cylinder liners feature race-derived transfer ports for
increased torque and knock resistance, similar to that developed for the
legendary 2.5 EFI consumer and race outboards. In addition, the cylinder block
exhaust chest is specially machined for optimal exhaust flow and power. The
modified exhaust adapter plate and center section reduce engine backpressure and
noise.
In addition to the race-inspired cylinder block, race-style cylinder heads
help separate the Pro Max 225X from all other 225 h.p. outboards. Using the same
casting as the 2.5 EFI Drag race heads, the new 225X o-ring cylinder heads
minimize cylinder bore distortion. Enlarged water chambers provide increased
water flow close to the combustion chambers and spark plugs, lowering engine
temperature for enhanced reliability and durability.
Electronic single point oil injection feeds oil to the fuel management
system vapor separator where it is mixed prior to being injected into the
engine. This highly reliable, variable-oiling system automatically adjusts the
fuel/oil ratio, delivering proper lubrication throughout the operating range.
The system automatically reduces the amount of oil at idle, minimizing smoke.
Internal enhancements include a crankshaft outfitted with nine seal rings.
The use of two additional seal rings, derived from race outboard development,
increases crankcase sealing for smoother engine running quality and better
overall performance.
Steel-cage rod bearings, placed between the top-guided connecting rods and
crankshaft journals, are used to enhance engine durability. New pistons feature
a custom profile that is unique to the 225X and a strengthened piston pin boss
casting that enhances durability. The pistons feature thin, high strength steel
rings (two per piston). The thin rings more easily conform to the cylinder bore,
simultaneously enhancing engine sealing while reducing friction.
The all-new fuel injection system features a lightweight, composite fuel
rail that is mounted vertically on the center of the intake plate. Rubber mounts
isolate vibration to the compact, composite fuel injectors mounted just in
front of the intake reeds. An inline fuel filter, mounted between the vapor
separator and fuel rail, provides added protection from debris entering the fuel
injectors. Rubber coated reed blocks cushion the impact of the five-petal,
single-stage composite reeds, greatly enhancing reed life without sacrificing
performance. The 225X uses the same air intake plenum as the OptiMax 200XS. The
flywheel cover/airbox has been modified for enhanced airflow.
All Pro Max 225X models are equipped with a digital SmartCraft Controller
Area Network (CAN) electronic control system. The CAN electronic control
computer processor optimizes fuel, spark timing and knock control for each
cylinder independently, enhancing engine running quality and performance. The
processor also operates the electronic singlepoint lubrication system. And, if
that were not enough, the Engine GuardianTM System monitors over 40 engine
functions to forewarn of possible problems that could lead to engine damage. The
CAN computer processor also drives SmartCraft System Monitor and accessory
System Gauges. The SC1000 System Monitor and accessory System Tachometer
calculate fuel flow and range. Additionally, both drive optional single-function
analog style System Link gauges. Models equipped with the 20" (508 mm) center
section and integral power trim come with a digital power trim sensor for
reading trim on the SC1000 System Monitor and or accessory System Link trim
gauges. A belt-driven alternator with 60-amp charging capacity makes running a
variety of electronic accessories worry-free.
The Pro Max 225X comes standard with the SC1000 System Monitor and hardware
that use a single data cable to connect an assortment of SmartCraft System
gauges for both single and multi-engine applications. In addition, the optional
SmartCraft System Speedometer accepts data from National Marine Electronics
Association (NMEA) GPS connections for read-out of highly accurate boat speeds.
Models are available with the 15" (381 mm) short shaft or 20" (508 mm)
standard center section. The 20" center section models are available with a
right-hand rotation 1.87:1 gear ratio Torque Master or Sport Master gearcase.
The 15" short shaft models feature the heavy-duty offshore swivel/clamp bracket
assembly, single-ram trim cylinder and the 1.87:1 Sport Master gearcase with
either right-hand or left-hand rotation.
