Hello, my father currently has a mercruiser 454 alpha 1 and recently broke a water pump. When we went to replace it, our mechanic suggested we flush out the hoses with water. Only problem is, the two noted designs for this mercruiser 454 (in this case an 88', but I believe there were only 2 water pump designs in general) do not seem to match the hose configuration for this engine. Also, it seems in both designs there is a heat exchanger of some sort (an oil cooler perhaps?) bellow/to the side of the engine which must be flushed too. However, the only item that seems to match this is the oil canister-type thingy across from the engine (I really wish the diagrams i have labeled that part) - there are no canisters bellow it, or anywhere near where the water pump was.
Can someone please identify which hose to flush! I feel like my head is about to explode! pictures here plus diagrams of the two water pump config's, which can be found at www.marinepartsplus.com
Here are the two configurations,first the older than the newer. It looks kind of like the older, but it's hardly identical. There are to many differences to count, you can see many of them here in the pictures
Note that under the thermostat (not the housing lid but the housing body under it) has no hoses coming out of it.
And here is the oil canister thingy...
