Keeping the ferry in Ardrossan is believed to require an investment of £30 million.
Troon have made a bit to run the service and can operate the service with no public money.
Former Ayr Labour MP Sandra Osborne said: "I'm not surprised that North Ayrshire Council is fighting to retain the Arran ferry at Ardrossan but the first duty of a local MP is to stand up for the area they represent.
"With Associated British Ports based in Ayr and bidding to bring the service to Troon within South Ayrshire, it is totally incomprehensible that Corri Wilson should not only back this motion but actually sponsor it.
"In her maiden speech she stressed how her priority would be to work for the local community - instead she seems to be a cuckoo in the nest."
Dr Philippa Whitford, who backs the Troon bid, said: "Naturally, I welcome the proposal from ABP to invest significant sums of money in the port at Troon and being designated as the dock for the Arran ferry would, of course, bring significant benefits to the town, not least in creating a connected tourism offering.
"However, the port for the ferry crossing should, first and foremost, be made with the people of Arran in mind and, in particular, what will provide them with the most reliable service and minimise weather related cancellations."
SNP MP Patricia Gibson also tabled an Early Day Motion criticising the Troon proposals. This motion was sponsored by SNP MPs Peter Grant, Richard Arkless, Neil Gray, Kirsten Oswald and Corri Wilson.
