Looking for Mercruiser Thermostat Housing

[spareparts]

skools, can you snap apicture of the one you need? The older ones preheated the water by allowing it to run thru the manifolds before it went inot the blok, works pretty good when its new and in fresh water. Anytime I repalce manifolds, I always update it to the new style and run the water outlets to the bottom of the manifolds, i also only use the 4 hole gaskets to let the water run out as fast as it wants. After they get some corrosion in them, it slows it down a little. by using the four hole gasets it keeps the manifolds from stopping up as quick. Down here, 4 seasons is about it for manifolds if you don't flush the engine, 6 seasons if you do. Basic power will have the best price on a new on for you
