I winterized my engine for the first time myself in the fall (with a lot of knowledge from this forum and the Moyer manual – thanks!). As part of that process I removed the thermostat and cleaned and tested it over the winter. This spring I put the thermostat back in, along with a new gasket from Moyer Marine. The installation seemed uneventful. With the boat now in the water, I have water leaking like a sieve around the thermostat housing.

Are there any non-obvious (or idiot-proof!) steps in getting the thermostat sealed correctly? It didn’t leak before I removed it, and from the looks of it hadn’t been removed for several years. The old gasket was stuck to the head and thermostat housing. I *thought* I did a good job of cleaning the old gasket off and left a clean surface for the new gasket to seal. If I take the housing off again to check it, will I need a new gasket or can I use the gasket I have?

Thanks,
Tim
