Boon (80) broke six world records in the age 75-79 grade at the Dunedin and Wanganui Masters Games in 2006 and 2007 and the South Island Masters Games in 2006.
But he wants more and is confident of achieving his goals when he moves into the over-80 grade.
"It will all happen tomorrow," Boon said from Timaru yesterday.
Boon, a retired builder, will compete in the 100m, 500m and 1000m this afternoon.
He has worked hard for his success, undertaking three one-hour weight sessions at the Unipol gymnasium each week. He also has a rowing machine at his Corstorphine home and uses it most days.
Boon, who started weight training at the age of 52 to heal a back injury, has been one of the stars of the New Zealand Masters Games over the past three years.
Shirley Godkin (Timaru), another world record-holder, will compete in the 100m, 500m, 1km and 2km.
She holds New Zealand records in all these indoor rowing events.
It is the eighth annual South Island Masters Games and the fifth to be held in Timaru. The games start today and run for a week.
There are 3500 athletes competing, 1700 of whom will be in action on the first weekend. Competitors range in age from 30 to 92.
There are 50 sports on the programme and these will be contested at 35 venues.
The two sports with the highest entries are netball (800 players) and football (300).
A Dunedin competitor who looks certain to win a gold medal in her age group is Barbara White (68), who is competing in the race walking events.
Aaron Joy, the manager of the New Zealand Masters Games in Dunedin, will be in Timaru to promote the Wanganui and Dunedin New Zealand Masters Games in 2009 and 2010.
