2002 Sea Ray 220 Sundeck that has water at times in the ski hatch after I wash the boat that does not drain. I have tried to use a fish tape and water pressure through the access hole right over the tube to clear it with no success. When the motor was out the mecanic could not see anything from the engine compartment. I think the gas tank is blocking the view. Anyone have experience with this? I am thinking of maybe using suction at the end of season to see what happens. Thank you, RR
