Formerly trained by Andrew Balding, Hoo Ya Mal was bought by new connections on the eve of Royal Ascot for the princely sum of £1.2million.
He outran his 150/1 odds at Epsom when finishing just two and a half lengths behind Desert Crown and will eventually join trainer Gai Waterhouse, with the Melbourne Cup a likely target.
Before then, however, Boughey has been tasked with a possible tilt at the St Leger.
Boughey told SBK: "It's very exciting to have a horse like Hoo Ya Mal in the yard.
"His work has been good and we are looking at the Gordon Stakes next before a possible tilt at the St Leger, before he heads to Australia with Gai Waterhouse for the Carnival out there."
