" We have water coming out the back of the boat," but do you have enough
water coming out the back?

Long ago, I had a similar issue and fixed it by removing the raw water
connection to the exhaust riser and cleared an accumulation of rust or salt
crystals at that connection inside the riser.  I simply jammed a pick or a
screw driver up into it to clear it.
