15 hp Enduro purchased in Antigua

[Callisto]

I lost my dinghy and engine on a crossing from St Barth to Antigua and purchased a 15hp Yahama Enduro there. It has been a great engine. My boat is back in Texas and the outboard needs a part (a casting where the tiller arm and the engine come together). The engine was viciously attacked by a mizzen boom during the passage.

Where can I get parts for an Yahama Enduro? I have heard that I have to go to Jamaica (Yahama Engines), where can I get a parts diagram so I know what parts to order?
