I have an engine from a 2003 AC sno pro that I am parting out. The motor never had the recall completed to lubricate the water pump shaft. This resulted in the shaft to seize up and over heat. The gear on the crank and the waterpump shaft were damaged. The crank should still be good, but needs to gear replaced, Crank, heads, pistons, CDI, Carbs, Stator are all available. Make offer if you need parts.
