Pentiful, who was posting her second win in eight starts, is among 27 horses Bosma has syndicated.
He decided to take on syndicating horses on a full-time basis after success with Silky Red Boxer, who won eight races, including the 2003 Japan-New Zealand Trophy at Tauranga and the 2003 Sunline Stakes at Te Rapa as well as two races in Sydney in 2006.
"I came home one day and told my wife I was giving up my job to syndicate horses," Bosma said.
"I am still married."
Pentiful, trained at Riccarton by Shane Marr, has had both her wins over 2000m.
Jock Collins, of Weston, a member of the 13-person syndicate who race Pentiful, was given a share in the horse for his 80th birthday last November.
Collins had his first win as an owner in a hurdles race at Gore in 1951 with Comeaway, trained by the late Stan McKay.
Collins raced Even George, the winner of seven races when trained by Neill Ridley.
