Evinrude 0310058 Thermostat Housing Seal Genuine OEM product	$3.50 ~~$4.12~~ In stock 5+ in stock	Best	OEM Evinrude thermostat housing seal that directly replaces the factory part used on many Johnson/Evinrude crossflow applications. The photo shows a metal‑jacketed outer shell with an elastomer inner lip; that reinforcement keeps the seal round and resistant to extrusion when the housing is torqued, improving long‑term leak resistance. This part also locates the thermostat in its pocket (the “grommet” function). Mechanics often note that a distorted or swollen grommet can make a thermostat stick, so the stiffer OEM construction is a plus. Excellent fit/finish and proven compatibility make this the benchmark choice.

EMP 27-00424 Thermostat Gasket (viewing this product) Aftermarket product	$1.52 ~~$1.79~~ In stock 5+ in stock	Better	EMP’s aftermarket thermostat gasket is an interchange for the same applications as the OEM seal. The photo shows a molded rubber ring with dual sealing ridges that mimic the OEM grommet profile to both seal and center the thermostat. EMP parts have a solid reputation for consistent molding and durometer (rubber hardness), which helps the gasket compress correctly without tearing. As with all grommet‑style thermostat seals, careful seating is important so the thermostat doesn’t bind in the rubber—an issue commonly discussed by owners when cooling problems persist after service.
