Pull the hose off on the outlet where the water comes out of the motor, you could have rubbish blocking it, you may need a piece of wire to pry out little stones etc, had to do it on my last motor often especially when you hit shallow water where you stir up the bottom.

found the problem. the water pump wasnt lined up with the tube going to the block. makes sense now. works great!
