My 1980 28' OD has the white vinyl/rubber bilge blower vent covers where they exit the deck at the aft end of the boat near (atop) the transom. These covers are cracked, worn and generally need replacement. I hesitate to replace them with metal or hard plastic cowels because they are in a vulnerable to damage area and soft material will take abuse better. If anyone knows where to locate these covers I would appreciate the lead. If Rudy has 'em and someone has bought them thru him that would be OK too. Thanks, Mike Pitterpat
