Ian Jolly admitted the seven offences against the four boys when he appeared at Aberdeen Sheriff Court on 19 December 2017.
The offences came to light after one of his victim contacted police having seen the publicity around the investigation into alleged abuse in football
The court heard that he abused one of the boys over a three year period from 1987 and also indecently assaulted, exposed himself to, or performed sex acts in front of, three others.
Speaking after the sentencing at Aberdeen Sheriff Court, Andy Shanks, Procurator Fiscal for Grampian Highlands & Islands said:
“Ian Jolly committed a number of serious sexual offences against boys.
“Although these crimes took place decades ago, this case, and others like it, show that justice can be achieved after many years.
"We strongly encourage anyone who has been a victim of any such offences to report this to the police, even after a significant passage of time, and they can be confident that they will be treated with the utmost professionalism and sensitivity by the police and our expert prosecutors.”
