Good To Know

Q: How do I know if my thermostat needs replacement? A: If your engine overheats or runs cold, the thermostat may be stuck open or closed. Replacing it restores proper temperature regulation.

Q: Will this thermostat work for my 25 HP Yamaha? A: Yes, it is designed for Yamaha 2-stroke outboards from 3 to 40 HP, including your 25 HP model, but always verify your engine's serial number for exact compatibility.
