Mercury 225CXL 225HP Outboard – 25in Shaft, Counter Rotation, DTS, V6

Description

Mount the counter-rotating, V8-powered Mercury 225CXL to eliminate port-side hull listing on twin-engine offshore setups. The massive 4600cc block delivers instant throttle translation, pushing heavy center consoles through steep morning swells. Verifying your 25-inch transom height ensures this counter rotating mercury outboard motor aligns correctly with your standard starboard engine.

Struggling to maintain voltage running multiple chartplotters? The high-output 85-amp alternator acts as an onboard mechanical power plant. You keep all marine electronics running simultaneously without draining house banks. Engineers paint this 239 kg block in Cold Fusion White using multi-stage marine primers. This physical barrier blocks severe paint blistering across years of high-salinity exposure when repowering offshore fishing boats.

Key Features of Mercury 225CXL

• Computer Controlled EFI: Optimizes fuel delivery dynamically across the 4800 to 5400 RPM range, maximizing offshore cruising range and combustion efficiency.
• 25-Inch XL Shaft: Drops the propeller deep below turbulent surface water, maintaining solid forward thrust in rough ocean conditions.
• Counter-Rotating Gears: Balances propeller torque against a standard rotation engine, forcing the hull to track perfectly straight underway.
• Digital Throttle and Shift: Eliminates mechanical cable friction completely, providing silky smooth gear engagement and exact electronic RPM control.
• 85-Amp Alternator: Outputs 1071 watts of charging power, keeping demanding radar systems and livewell pumps fully powered offshore.
• Cold Fusion White Paint: Reflects intense ultraviolet sunlight physically, preventing cosmetic fading and matching modern fiberglass hull finishes perfectly.
• Through-Prop Exhaust Hub: Buries loud V8 engine noise and raw combustion fumes deep below the ocean surface for a quieter ride.
• Top-Cowl Service Door: Provides direct access to the oil dipstick, simplifying routine fluid checks without removing the heavy engine cover.
• 1.85:1 Gearcase Ratio: Transfers massive V8 torque to the propeller shaft securely, turning large diameter props without slipping.
• Naturally Aspirated V8: Eliminates complex supercharger piping entirely, reducing mechanical failure points when operating miles from the marina.

Why Choose Mercury 225CXL

This exact model acts strictly as the port-side companion in a multi-engine application. It requires a 25-inch transom and compatible digital helm controls. You cannot run this as a single engine without fighting severe steering torque. Proper mercury outboards digital throttle syncing is mandatory.

• Verify your twin-engine transom bracket accommodates a 25-inch shaft length.
• Install a compatible DTS helm binnacle to synchronize shift inputs across both outboards.
• Comply with stringent saltwater emission laws using highly regulated four-stroke combustion.

Ideal Application and Vessel Fitment

This counter-rotating powerhouse is engineered strictly for multi-engine deep-V center consoles and heavy offshore walkaround hulls. Operating as the port-side drive in a twin engine mercury outboard setup, it actively cancels starboard propeller torque to keep the vessel tracking perfectly straight across steep ocean swells. It excels in blue water tournament fishing and long-distance offshore runs where balancing thrust, managing heavy passenger payloads, and fighting unpredictable crosscurrents require precise, synchronized multi-engine power.

Warranty, Support and Maintenance

Authorized recreational operation receives a 3-Year Limited Warranty alongside a 3-Year Corrosion Warranty. Registered commercial applications fall under a strict 1-Year Limited Warranty with zero corrosion coverage applied to the block. Scheduled maintenance requires replacing gearcase lubricants and changing oil filters at manual-specified intervals. Always save all physical service records. Your engine serial number acts as the only way to source exact genuine replacement parts. Mulmotor can assist with product details and order-related questions before purchase.
