Try Waterway
Last year I got some pretty obscure Renault parts (transmission bearings and seals) from Waterway Marine:Waterway Marine Service, Inc.2017 Renard CourtAnnapolis, MD 21401Phone: 410-266-0590FAX: 410-266-0534They get the parts from Nanni in France. They only deal wholesale so you might have to have your marina or shop order them for you.I just tried to check their web site but it looks like its been hijacked. Good luck.Dan Bryant
