At 2800lbs., you could get something else to pull the boat and not run up against the max tow limit. You could always rent a truck from Uhaul, Lowes, or Home Depot for when you need to take the boat into the shop and then pick it up. The amount of money spent on renting a truck for a couple days is cheaper than having to put new gears, bearings and bushings in an axle twice.
