I have just replaced the manifolds and risers on my 2004 mercruiser stern drive. While the manifolds were off I also replaced the sea water pump, fuel filters and spark plugs. When finished I noticed there was no water circulating. None at all coming out the outlets on the leg. I think I may have the impeller around the wrong way but before I start pulling it apart is there anything else I may have missed. What hose can be disconnected to check if the pump is working?
