Just purchased this, Boat. 234 hours Volvo Penta 4.3 motor. Boat runs and drives great. However there seems to be an excessive gas smell from the motor compartment even after the blower runs. also noticed a whitish bilge water once when I emptied it. I emptied the bilge before I bought the boat and it seemed fine. although it was sitting for a month or so and probably accumulated some rain water. Motor oil is new clean and water free. Any thoughts are appreciated. Thanks
