I bought this boat and it was all like new. 1998 model motor. put a new water pump in it and it would not pump with the flusher on the lower unit. pulled the screen off the lower unit where the water intake is suppose to be and there is no hole anywhere behind the screen. It will take water in a little weep hole on the lower unit about 4 inches from the screen. I put the boat in the water and it pumps OK. Is this normal or did the factory not drill out a hole behind the intake screen? Thanks for any input. Skipper
