High-performance replacement and repair kit for Yamaha Super BN 44mm outboard motor carburetors, Kawasaki 440, 550, 650, dual and triple clutch linkages--BIEMMEDUE

This professional outboard carburetor is specifically designed for Yamaha Super BN 44mm models and Kawasaki 440, 550, and 650 series outboards. Meeting OEM specifications and marine operating requirements, it offers a direct replacement or upgrade solution to address performance issues, excessive fuel consumption, and starting problems commonly encountered with older carburetors. 【Key Features and Optimization for Marine Use】 Precision Tuning for Marine Use: Specifically optimized for the high speeds, heavy loads, and high humidity of two-stroke outboards, it ensures rapid acceleration and stable high-speed operation with a precisely preset air-fuel ratio. Corrosion-Resistant Construction: The main body is constructed from splash-proof aluminum alloy, while the internal metering jet, needle valve, and spring are made of stainless steel or brass. The main seals are made of ethanol-resistant marine rubber, providing lasting protection against seawater corrosion. Dual/Triple Synchronous Carburetors: On multi-cylinder engines, a rigid linkage mechanism (exact details vary by kit) ensures synchronized fuel delivery to each cylinder, resulting in smooth engine operation and optimal performance. Maintenance-Friendly Design: Featuring a removable float chamber, external mixture adjustment screw, and a clear fuel path, these carburetors allow for easy cleaning, maintenance, and fine-tuning, even on the water. 【Compatible Models】 Yamaha: Compatible with select Super BN series outboard motors with a 44mm carburetor bore (please check your engine model or original part number). Kawasaki: Compatible with classic 440cc, 550cc, and 650cc two-stroke engines found in jet skis or outboard motors (e.g., JS440, JS550, and JS650). (Important: Due to the complexity of outboard motor model years, please send the seller photos of your old part or the motor part number to confirm compatibility.)
