Sorry, no luck from me. I have access to 2 lists to search, but one is for those leaving the UK only. There is a Michael Maye of roughly the right age shown but only much later, leaving from Southampton to Montreal in 1956.
The other shows immigration into the UK but I'm not sure it includes arrivals from Ireland. Certainly no Michael Maye or Michael James Maye showed up for those years.
Sorry I couldn't be more help
