Finally Solved My Overheating Issues!

Replaced the thermostat on my 40HP Nissan outboard with this unit. Installation was quick and simple - no modifications needed. The engine now warms up faster and maintains steady temperature even at full throttle. After two months of saltwater use, no corrosion or sticking issues. Works exactly as described and solved my cooling problems. Great value!
