your always going to get some fuelly residue with water comimg out. exhaust comes out prop with water, unburnt fuel and oil goes with it. if its really bad, carbs may need cleaning to get out varnish and crud from old fuel. you should probably change water pump impeller as it will fail from sitting. they need changing ever year to 2 years. check lower leg lube oil and make sure its not milky from water getting in or lube blowing out with flush water.
