Bob Fulton has ended his 50-year association with Manly.
The Daily Telegraph reports Fulton has notified club owners Rick and Scott Penn he is walking away.
Fulton, who turns 70 in December, led the Sea Eagles to three premierships as a player (1973,76,78) and two as coach (1987,1996).
That is five of the eight titles the club has won in it's 70-year history.
His latest role was overseeing a two-year multi-million dollar restructure at the club.
“The timing is right,” Fulton told The Daily Telegraph.
“I did a handshake deal with Rick and Scott Penn two years ago that I’d stay for as long as it takes to restructure the football department from junior reps and development through to first grade.
“Given our achievements of winning the Holden Cup, making the grand final of Harold Matthews and finishing sixth in the NRL when most experts suggested we wouldn’t make the finals convinced me the club is now in great shape and it was the right time.”
Fulton started his career as a Manly rookie in 1966 and has arguably been the club’s most influential patriarch.
He oversaw Manly’s latest overhaul which saw the departures of Brett and Glenn Stewart, Anthony Watmough, Kieran Foran and Jamie Lyon as well as almost 20 others.
He recruited Marty Taupau, Blake Green, Trbojovic brothers Tom and Jake as well as
manoeuvring the re-signing of star Daly Cherry-Evans.
Fulton also oversaw the tough decision to sack club legend and former coach Geoff Toovey and appoint Trent Barrett who took the Sea Eagles to sixth-place and their first finals campaign in three years this season.
“It’s been a hectic ride,” Fulton said, “I struck gold with my decision to appoint Trent Barrett as head coach.
“Baz has achieved results no one thought would be possible two years ago. There are not many coaches that tick all the boxes but Trent is one of them.”
Sea Eagles patriarch Ken Arthurson praised Fulton’s life-long commitment to Manly’s success.
“It was inevitable that Bozo would walk away once he’d completed his commitment to the Penn family,” Arthurson said.
“I honestly doubt any other person could have achieved what he has in such a short time. Knowing him like I do, I suspected he’d exit gracefully and he’s doing just that.
“It’s been remarkable what he’s done. He has given his all for the club and he’s now at an age where he wants to spend more time with his wife Ann and his extended family.”
Fulton remains a Kangaroos selector and 2GB commentator on the Continuous Call team.
