I have a 2003 Typhoon ( Concourse with storm 1 package) and had to make the impeller change myself this weekend. Im not certain how common this is for all Centurions, however mine is a split transom. Making the Drivers side virtually unserviceable. However, the passenger side the large locker wall is removable. Here is the life saver.... if you have an extra set of hands to help with this project.... pull the hinge pins on the engine cover. With the engine cover removed you can do alot of work from the swim deck. remove the belt and the engine water pump. If you can, replace the gaskets. If you can't replacement... be careful not to damage them during removal and use High Temp Silicon and allow to cure for 24 hours before water testing. Once you get the Engine water pump off you and your buddy c an work from top and side to remove the fresh water pump. Pull the impeller and replace with new... Yes, the impeller you receive will not look like it fits ... you have to "spin" the impeller to create the correct shape. A little white grease or engine oil helps...although can be done with out it. Add HT silicon to the fresh water pump rubber gasket to hold it in place while reinstalling... reinstall the engine water pump and connect all hoses. Be patient and let the silicon set. I would recommend doing this in dry dock or on trailer and not in the water just to prevent water and silicon mixing.
