After carefully rebuilding the top end of my 1986 Mercruiser 260, it purrs like a kitten. During rebuilding, I replaced the lower thermostat housing with a new one with all new internal parts and thermostat. The old lower housing (which was there from the previous owner) didn't have a solid metal thermostat sleeve (Mercruiser part # 23-47508T). Naturally, I ordered and put a new one inside my new lower housing.
Out of curiosity, what's the function of this solid metal sleeve (besides holding down the thermostat). I was initially worried that the metal ring, being solid, would block a couple of flow passages.
