As the title says how hard or difficult of a job is this to do for someone totally new to outboards. I just bought this used motor and a buddy and I tested it out in my driveway and discovered the leak. Alternately if I do not do this myself how much am I looking at for a shop to do this? I am in Canada

What motor model and year? What's a block cover gasket? Do you mean an exhaust cover gasket? An exhaust cover gasket is totally easy to change IF you can get to the bolts without removing the powerhead and WITHOUT breaking the bolts (sometimes they corrode and seize and you will twist off the bolt heads. IF it's a water jacket cover gasket, it's easy. Not sure what merc you have. Lots of mercs don't have a removeable cylinder head.

Is it leaking water around a spark plug?
