Evinrude 0345171 Thermostat Spring Genuine OEM product	$15.36 In stock 5+ in stock	Best	OEM BRP/Evinrude thermostat spring for 90° V6 3.3/3.4L FICHT and E‑TEC 200–300 HP applications (1999–2012), so fit and preload match factory calibration. This part also supersedes 0769135, reducing risk of mixing old and new specs. Photo details (dull bronze finish, close‑wound coils, unmarked ends) are consistent with factory hardware. In a thermostat, the spring supplies the closing force against the wax‑pellet valve; if its spring rate (stiffness) is off, the opening temperature and valve travel can shift, affecting idle temperature control. Choosing the OEM spring minimizes those variables and is the safest pick when diagnosing heat‑related issues. Note: many owner reports of Evinrude overheating trace to debris or water‑tube alignment rather than the spring—using the correct OEM part helps eliminate parts‑spec uncertainty while you troubleshoot.

GLM Marine 13827 Spring (13827) (viewing this product) Aftermarket product	$10.48~~$13.10~~ In stock 5+ in stock	Better	GLM 13827 directly cross‑references to BRP 0345171 and is listed for the same 90° V6 3.3/3.4L 200–300 HP models (1999–2012), so it’s a credible interchange. Your photo/notes show a spring with the same apparent coil count and dimensions; the dull silver vs. bronze color is typically a finish difference and not performance‑critical if the spring rate matches. As with any thermostat spring, correct free length and stiffness matter because they set valve preload—too soft opens early, too stiff opens late. This GLM piece is a practical choice when OEM is unavailable; however, because cooling‑system behavior on these motors can be sensitive, OEM remains the benchmark for exact calibration. If overheating persists after replacement, check for blockages or misaligned water‑tube connections, which owners commonly report as root causes.
