Precision Ignition Timing & High Output: Accurately controls high-voltage capacitor discharge timing matching OEM advance curves, ensuring complete combustion, smooth idling, and responsive throttle power.
Marine-Grade Waterproof Encapsulation: Fully potted with thermo-setting epoxy resin to seal out saltwater spray, moisture, and intense vibration, preventing internal circuit shorting.
Thermal & EMI Resistance: Engineered with heat-resistant components and electromagnetic interference shielding to operate reliably under extreme engine compartment temperatures.
Primarily compatible with Yamaha 2-stroke 40HP outboard engine platforms (featuring the 6F6 model code):
Yamaha 2-Stroke 40HP Series: 40HP, 40J, 40Q, J40, Q40 (2-cylinder 2-stroke outboard platforms).
PREMARINE Direct Replacement: PREMARINE manufactures high-precision aftermarket CDI units engineered to exact OEM 6F6-85540 mounting holes, wire color codes, and pin connectors for seamless plug-and-play installation.
PREMARINE Quality & Marine Protection: Built with upgraded high-voltage capacitors and durable flame-retardant housings, PREMARINE CDI modules deliver exceptional reliability and high cost-efficiency for Yamaha 40HP owners.
No Spark / Engine Fails to Start: A blown capacitor or burned circuit inside the CDI prevents high-voltage pulse generation, leaving spark plugs without ignition spark. Inspect stator/coil input and replace the CDI.
High-RPM Misfires & Power Loss: Thermal breakdown of internal electronic components under high engine RPMs causes intermittent ignition cutting, speed drops, or engine bogging.
Single-Cylinder Dropout / Severe Engine Shaking: If one discharge channel fails inside the dual-cylinder CDI, a cylinder drops out completely, causing severe vibration and drastic power loss. Replace the faulty CDI assembly promptly.
