87290A4 Mercruiser Thermostat Housing Assembly

Regular price $299.00 USD
Regular price Sale price $299.00 USD
Sale Sold out

This is a used, like brand new thermostat housing. It is a genuine Mercury Marine part, not aftermarket. I am told it was bolted on and ran on a hose and then removed. It has never been to the lake or ocean. By the looks of it I can believe it, there is still paint on the springs for the nylon balls. This will fit many different models and years. It is the very common “design 1” found on 4.3, 5.0, and 5.7 liter engines. It is also found on some 454, 502, and 500 Bulldog engines.
