Ecclestone revealed last October that three parties were interested in completing an F1 takeover, but said the interested bidders all wanted him to stay on as chief executive, Omnisport reported.
Marchionne has saluted the work done by Ecclestone, but said the 85-year-old should be looking beyond his time in power.
"Ecclestone knows that he is not going to be there forever and maybe this is also connected to the future of FOM [Formula One Management]." Autosport.com quoted Marchionne as saying.
"The real challenge for Bernie is to get organized. He needs to come up with a system where maybe some responsibilities can be developed differently.
"We have a responsibility to deliver a certain level of sound management continuity of Formula 1 with FIA and with FOM.
"So we really need to make the most of Bernie's ability to develop this sport in the best possible way. Believe me it is not easy.
"Bernie is quite a character, but he is a very nice guy and has an incredible strength.
"I don't know what I will do when I'm his age. What he has done over the last 10 years is incredible and he's still there."
Marchionne added, "Bernie should pave the way to prepare the future of the F1 world.
"This age issue is there, so we should ask ourselves: are we appealing to young people?
"This sport has great potential which has not been expressed yet. We need to make it entertaining because if everything is predictable, it gets boring.
"We should try to deliver more unpredictability, so to speak, so that results are unpredictable."
