It will cost you $300 to $400 for winterization for a job you can do and know that it's done right for about $40 to $50. It takes a about 6 to 8 hours but in those hours I also remove all water spots and wax the boat.
Just about every person I know that pay's someone has had a issue with the winterization. Cracked ballast pumps, clogged fuel filter, shredded impeller, nothing like a cracked block just little things.
