[QUOTE="Pappy, post: 395059, member: 3278"] Sure! Water flows from the water pump up the water tube to the adapter. From there the water enters the exhaust cover, through passages in the exhaust cover to cool the exhaust and immediately activates the overboard indicator. Water then enters the block from the exhaust cover, flows around the cylinders from bottom port up and over to bottom stbd side. From the bottom stbd side of the block water enters the bottom of the cylinder head and flows up and around the cyl. head. From the top of the cylinder head water enters the thermostat cavity where, at a low speed water temp is regulated by the thermostat. Water then flows down the cylinder head cover from the thermostat cover and exits the powerhead. Part of the hot water also recirculates from the cyl. head cover back through the exhaust cover to minimize thermal shock in that area before it travels back into the block and exits. [/QUOTE]
