I have a new 115 Yamaha, with two hours on it. The second time I tried to flush the engine by connecting the garden hose, no water came out of the pee hole. I lowered the engine back into the water and ran the engine to make sure the water pump was working, and got a steady flow out of the pee hole. I attached the garden hose to my 9.9 Yamaha just to make sure it wasn't a water pressure issue, etc., and got a steady stream out of that engine. I tried to ""Google" the problem, but came up empty. Any ideas on what my problem may be? Thanks
