| Product | Price | Rating | Comment |
|---|---|---|---|
| Yamaha Motors 6H3-12411-11-00 Thermostat (viewing this product) Genuine OEM product | $29.20 In stock 5+ in stock | Best | Genuine Yamaha thermostat made in Japan with clean, precise stamping and consistent metal finishing. Copper/brass body, stainless spring, and properly sized rubber seal match OEM design intent and provide the highest confidence in correct 50°C regulation and fit. |
| OMAX OMAX-6H3-12411-11 THERMOSTAT Aftermarket product | $1.00 In stock Only 1 remaining | Better | European-made thermostat that closely mirrors the OEM layout (metal body, stainless spring, rubber seal, and 50°C marking). Small differences in the top valve disc and spring seating show it is not the same sub-manufacturer as Yamaha, but overall construction appears high quality among the aftermarket options. |
| GLM Marine 13320 Thermostat (13320) Aftermarket product | $21.62 In stock 5+ in stock | Good | Taiwan-made unit with a thicker cast/machined-looking brass frame, steel spring, copper actuator, and rubber gasket. The construction and marking placement differ notably from the OEM-style stamped frame, so while it should function, it is not an OEM-equivalent build. |
| EMP 75-75507 Thermostat Aftermarket product | $23.79 In stock Only 3 remaining | Good | Taiwan-made thermostat using a brass frame, copper thermal element stamped 50°C, stainless spring, and a rubber sealing ring. Valve plate geometry and stamping/finish details differ from the Yamaha part, indicating different tooling and slightly less refined manufacturing, but it should serve as a functional replacement. |
| Recmar REC6H3-12411-10 THERMOSTAT KIT (REC6H3-12411-10) Aftermarket product | $13.76 In stock 5+ in stock | Good | China-made thermostat kit with branded stamping on the support bridge and a 50°C marking, using the expected wax-pellet style mechanism and a rubber sealing ring. The geometry and surface finish differ from the OEM part, reducing confidence in long-term consistency compared with Japanese/European manufacturing. |
| Peach Motors PM-6E5-12411-30-00 Thermostat (50C) Aftermarket product | $28.25 | Unknown | We are working hard to determine a rating based on all available information, including product and manufacturing specifications. |
