Sierra Thermostat 130 Degree, Replaces 5001036, Fits Evinrude E200 E225 E250 & Johnson J200 J225 J250 Outboards

This Sierra thermostat is a direct-fit replacement for select Evinrude and Johnson outboard engines, designed to maintain correct engine operating temperature by opening at 130 degrees Fahrenheit. Proper thermostat function is critical on a marine outboard: it regulates coolant flow through the powerhead so the engine reaches and holds its intended operating temperature, protecting against overheating on one end and inefficient, incomplete combustion from running too cool on the other. A worn, stuck, or corroded thermostat is a common cause of erratic temperature gauge readings, overheating alarms, or reduced performance, and replacing it is standard maintenance for these outboard models.

This thermostat is sold under Sierra part number 18-3545 and is built to replace the original equipment thermostat rated for the same 130 degree opening temperature, so it drops in without requiring a change in cooling system calibration. It is designed to fit Evinrude E200, E225, and E250 outboards (2000-05) and Johnson J200, J225, and J250 outboards (2000-01).
