Used Mark 20H Ally Crank cases. The second from the top on the left side is an NOS case listed in our New Parts section. The other seven cases vary in condition from very good to a couple that need work due to welding. The prices range from $400 for the good ones to $100 for the one with a ton of welding where a rod went thru the bottom section of the case. Remember these cases were special built for use in the Pro Alky outboard racing division and will not run gasoline. Shipping is extra.
