Richard Mackie (Mackey) My search on the IGI turned up good name matches for the search criteria I used:
Male d.o.b: 11 Feb 1765. Baptism date & place: 17 Feb 1765, Stronsay, Orkney, Father’s name Peter Mackey; Mother’s name Elspeth Wasson.
He was also recruited in Kirkwall Roads and was subsequently rated as an ‘ordinary seaman’ before he joined the Pandora. The David‘s musters gives Mackey’s age as 24 when he was recruited, so he would have been 25 years old when he died.
