More about this item

EMP 75-08631 Thermostats & Parts

Johnson and Evinrude looper outboards have a well-earned reputation for durability, and keeping the cooling system properly maintained is a big part of why they last as long as they do. The thermostat plays a central role in that system, regulating coolant flow to keep the engine operating within its designed temperature range. This thermostat opens at 143 degrees Fahrenheit, which is the correct operating temperature for the listed looper applications. Using the right opening temperature matters because a thermostat that opens too early causes the engine to run cold and lose efficiency, while one that opens too late allows temperatures to climb toward the overheat threshold before coolant flow kicks in.

The EMP 75-08631 Thermostat fits BRP Johnson and Evinrude V4 looper outboards in the 90 to 115 horsepower range and V6 looper outboards in the 150 to 175 horsepower range, covering model year 1991 and later. It is a direct replacement for BRP part number 435491 and also crosses with Sierra 18-3544, GLM 13130, and Mallory 9-43032. If you are cross-referencing from any of those numbers, you are in the right place.

EMP manufactures this thermostat to OEM specifications, so the opening temperature, flow characteristics, and physical dimensions match the original exactly. Thermostat replacement is a straightforward service item that is easy to include in a seasonal tune-up, and on a looper engine that sees regular use, staying ahead of cooling system maintenance is always the smarter play.
