I have a 19'6 sea fox bay boat. Since owning it the aerator will air lock when first putting boat in water. Have switched aerators to one supposed to be anti air lock. Have no loose connections, have shortened connection from pump to peacock. No luck. Have to undo hose from livewell and get a mouthful of salt water to get going. Not drink of choice at 5:30 am. Any help appreciated.
