Mercury 1999 to 2005 25 HP 4 stroke short shaft 15” 2.42:1 gear ratio. Mercury part number 821306T32 This lower unit has the shift rod that moves up/down to change the gears.

If you are not 110% sure send me your S/N and I’ll verify fitment.

1 year warranty. I am the expert with these lower units. I've seen a lot so I know a lot. I can properly fix what others turn in to scrap parts. I am so good that I will stand behind my lower units for a full year. They are that trouble free. Who else will do that? Mercury will not do that on a brand new one.

This lower unit is a super clean, fresh water part. The lower unit will be a completely rebuilt using as needed new bearings, seals and impeller.

Pressure check and fill with Mercury Premium High Performance gear lube.

This lower unit will come to you ready to bolt on and use, no excuses just good work and parts.

Or, I can rebuild your lower unit and make it work like new.

Either way the lower will be ready to bolt on your motor and use and with proper care will give you years of fun (with proper maintenance) for a fraction of cost of a new one.

There is only one way to tell if one of these lower units is really good, and that is to take it apart and look.

Look at my feedback and the items I sell and notice I have sold hundreds (yes, hundreds) of Mercury lower units this on eBay. Now that is assurance you just don't see everyday in the eBay world. 

I was a Mercury Certified Mechanic and I have been fixing boat motors longer than I really care to admit.

Shipping is in a custom professionally packaged box. This gets your lower unit from here to you looking just like it left my shop. Shipping is for lower 48 anywhere else please ask.
