I guess once I get my machine back, I may find out. But I do notice there are two 'things' mounted to the bottom of the hull on either side of the shaft (on the inside 8). not sure if those are pumps, or what. also, I can't see where the water goes out. (my tigarshark has a hole at the side of the hull were you can see the water comming out when its running.) My Tigar shark also has water filter - which I have to clean after running it into sand bars. Wondered if the SeaDoo GTS also has a water filter. Perhaps I should get a service manual for simple things.
