I got to shallow Sunday and sucked my 225 PM full of sand. I have pulled the LU off replaced water pump, rempved the T stats flushed the engine with a hose ,up through the water tube till it ran out the T stat holes and back down through the block till sand stopped comeing out . but still not peeing right. so I took the LU back off pulled the popet valve and the small hose in back was packed so I ran water up through the tube again and it came out the big hole .I ran wter in the small hole and think it is cleared out but I don't see where the sand went ,it did not come out on the ground that I can see.
Now I said all that to ask this. Where does the small hole go ? so I can try to back flush it and make sure it is clean. Thanks ibn avance for all assistance
