the bow exit hole?... is there not a thru hull fitting that the drain hose attaches to?.... the sealant that can be used to seal under the thru hull fitting could be about anything... plumbers putty, 3M-4000, silicone, boat life, ect....Does anyone know exactly what flexible "sealant" was used to "seal" the anchor locker drain hose at the bow exit hole? I know the solution to the leak problem but was curious as to what was used originally. Thanks Roger
