ITACO Thermostats Editorial Review
The Boat Motor Cylinder Thermostat 6H3-12411-11 10 01 for Yamaha Outboard has had mixed reviews from customers. Some customers found that the thermostat did not work for their specific outboard engine, such as the Nissan 70hp outboard and the Yamaha 150 fourstroke. However, other customers had positive experiences with the thermostat fitting their engines perfectly, such as the 2004 4HP 4 Stroke Yamaha outboard, the 30HP 98 Tohatsu, and the Mercury 4 stroke 6 HP. Additionally, one customer mentioned excellent customer service when the part did not fit. Overall, it seems that the compatibility of the thermostat with different engine models may vary.
