Maretron Exhaust Gas Temp Probe

The Maretron Exhaust Gas Temp Probe is an essential engine monitoring instrument for serious performance enthusiasts and marine mechanics who demand real-time data on combustion efficiency and engine health. Whether you're tuning a modified engine, diagnosing detonation issues, or monitoring a high-performance build in a marine environment, this probe delivers accurate exhaust gas temperature (EGT) readings that inform critical fuel and ignition adjustments.

EGT measurement is foundational to understanding how your engine responds to modifications, boost levels, and fuel quality—making this probe indispensable for anyone pushing beyond stock parameters. This Maretron probe integrates seamlessly into modern marine electronic monitoring systems, offering precision temperature sensing at the exhaust manifold or collector where combustion dynamics are most revealing. The robust construction withstands extreme thermal cycling and vibration inherent to high-RPM operation, ensuring durability and measurement accuracy.

Tuners and engine builders rely on EGT probes like this to validate fuel mapping, confirm proper ignition timing, and detect lean-running conditions that threaten engine longevity—particularly critical when running forced induction or exotic fuels. The compact 4 × 1 × 6 inch form factor and lightweight design allow for discreet installation in tight engine bays, making it a versatile choice for performance tuning in marine applications.
