I have an Evinrude 150 anniversary edition (I think 1984).It cranks ok on land with the water hose but won't even fire in the water.I think water is being pulled into it somewhere and getting into my fuel or killing my spark.It turns over great.When I run it with the water hose there is water coming out of a hole directly over the right side spark plugs and draining down on them.Is this normal?There is also a little water comin out of certain parts of the lower unit that don't look normal.
