Mercury Marine Mercury Can-P Gateway Module #8M0165589 $728.02
Mercury Marine 8M0165589 Modules The Mercury Marine 8M0165589 is a CAN-P Gateway Module used in Mercury's SmartCraft digital network system. It acts as a communication bridge between CAN bus devices on your vessel, translating and routing data between components that need to talk to each other but speak slightly different protocols. If your gauges, engine, and accessories aren't communicating correctly, this module is often the piece that ties it all together. This is an OEM Mercury Marine replacement part, built to the same specs as the original. It's not a universal aftermarket module, so fitment is specific to compatible Mercury SmartCraft-equipped engines and vessel systems. Verify your engine model and serial number against Mercury's parts catalog before ordering. OEM Mercury Marine replacement part Part Number: 8M0165589 Function: CAN-P gateway for SmartCraft digital network communication Connects and translates data between CAN bus-compatible devices Compatible with select Mercury SmartCraft-equipped outboard and sterndrive applications Sold individually Normalized SKU: 8M0165589UPC Code: 745061261099

Mercury Marine Qualifies for Free Shipping Mercury Thrust Vector Module TVM #8M0047524
Mercury Marine Mercury Thrust Vector Module TVM #8M0047524 $1,199.99
Mercury Marine 8M0047524 Modules The Mercury Thrust Vector Module, commonly referred to as the TVM, is one of the more sophisticated components in Mercury's advanced outboard steering and control systems. The Mercury Marine 8M0047524 TVM is a genuine OEM replacement module that restores the thrust vectoring capability built into compatible Mercury outboard applications, giving you back the precise, responsive handling that makes these systems stand out on the water. Thrust vectoring in a marine outboard context means the engine can redirect thrust to assist with steering and boat control in ways that go beyond traditional mechanical steering alone. The TVM works in coordination with Mercury's digital control systems to manage thrust direction, improving low-speed maneuverability, reducing steering effort, and enhancing overall handling response. On larger outboards and multi-engine installations where precise control matters most, the TVM is a key part of what makes the system perform the way it does. When the TVM fails or begins to malfunction, the symptoms typically show up as degraded steering response, error codes in the engine management system, or handling behavior that feels inconsistent or unpredictable. Because the TVM is deeply integrated with Mercury's digital throttle and shift controls, a genuine OEM replacement is the correct path forward. The 8M0047524 is built to Mercury's exact specifications for calibration, communication protocols, and mechanical function, ensuring seamless integration with the rest of the control system. Key Features: Genuine Mercury Marine OEM Thrust Vector Module (TVM) Part Number: 8M0047524 Designed for compatible Mercury advanced outboard control systems OEM calibration and digital control system compatibility Restores full thrust vectoring and handling performance Direct replacement with no modification required Figure #12 Confirm your engine model, serial number, and control system configuration before ordering. The TVM is specific to certain Mercury outboard applications and control system generations, and verifying compatibility with your setup ensures correct integration and full system performance after installation.

Mercury Marine Mercury PCM Propulsion Control Module #865857T05 $2,867.49
Mercury Marine 865857T05 Modules The PCM is the brain of your Mercury propulsion system. It controls fuel delivery, ignition timing, throttle response, shift logic, and a dozen other functions that determine how your engine starts, runs, and performs under load. When it fails, you'll know — hard starts, limp mode, erratic behavior, or a complete no-start are all on the table. And unlike most engine parts, there's no workaround. If the PCM is gone, the engine doesn't run. The #865857T05 is a genuine Mercury OEM Propulsion Control Module, not a remanufactured unit or an aftermarket substitute. At this level of the engine management system, genuine matters. Mercury programs these modules to exact calibration specs for the specific engine application — fuel maps, rev limiters, shift points, and protection parameters are all baked in from the factory. An incorrect or improperly calibrated module can cause poor performance, fault codes, or damage to other drivetrain components. This is a significant investment, and it deserves a call before you order. Our team can help confirm fitment and walk you through what to expect with installation and any required calibration steps. Reach us at 816-841-3364 — we'd rather spend five minutes on the phone with you now than have you deal with a return or a misapplication later. When you need the right PCM, this is it.
