Just put my boat in the water after having it sit for the winter. Everything went great except I am afraid my water pump/inpeller not working. I have a 1993 70 force where the water is injected out the rear of the motor. There is not any water coming out now. I ran it for about 3 minutes and still no water. I am supposed to have an emergency horn that sounds if the motor gets hot but it has not sounded. Could I have another problem? The hole is not clogged up and either is the hose that the water travels from. Anybody have any ways that I can check to see if its the water pump or impeller without taking the engine to the shop or could I change the impeller myself with my limited mechanical skills? Thanks
