WATERWICH Starter for GY6 150cc & 200cc Engines — 12V PMDD, CW 9-Tooth

WATERWICH Starter is a 12V PMDD electric starter built to replace worn starters on GY6-based 150cc and 200cc scooters, ATVs, mopeds and go-karts.

Designed as a drop-in replacement for several common OEM numbers, this compact starter delivers reliable cranking power for Chinese-made GY6 engines. It fits a wide range of recreational vehicles and utility machines and is engineered for straightforward installation without specialty tools. The unit uses a clockwise (CW) rotation, has nine teeth on the pinion, and balances strong torque with low electrical draw for consistent starting performance.

Which engines and vehicles will this starter fit?

This starter is compatible with most GY6-style 150cc and 200cc engines found on Chinese-manufactured scooters, ATVs, mopeds, go-karts, quads and small dirt bikes. It replaces several OEM part numbers used across brands, making it a versatile choice for common powertrain setups.

• Fits GY6 150cc and 200cc engine platforms
• Compatible with Tao Tao, Coolster, Jonway, Baja, Roketa and similar models
• Replacement for OEM 35850-286-007, 35850-286-027, 35850-286-017, 35850-375-000
