This lower unit qualifies for a 6 month warranty. The 6 month warranty will only cover the gears if there is a mishap. This does NOT cover seals.  The warranty is validated by your core.  In order to qualify for this, you must send in that core.  Both shafts must spin and it must be complete.  We will send a label for you to return your core in our box after receipt of the unit you’ve purchased.  If you do not have a spinning core, you may call in after your purchase and buy the 6 month warranty for 10% of the purchase price.  If you do not return a core or purchase a warranty, this unit will be sold with a 45 day warranty and nothing more or less.
