I needed a replacement starter for my mower and wasn’t completely sure which one would fit. I sent them a message and they got back to me quickly, asked for my model information, and helped confirm the right part before I ordered. Everything was handled professionally and the communication was great. Very happy with the service.

Good To Know

Q: What does the 50℃ rating mean for my Suzuki outboard? A: The 50℃ thermostat begins to open when the coolant reaches 50 degrees Celsius, allowing the engine to warm up quickly and maintain a stable temperature under load.

Q: How do I know if this thermostat is the correct part for my engine? A: Verify your engine's serial number range and cross-reference the OEM part number 17670-90J21 against your service manual to confirm exact compatibility.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
