Replaces Most Mercury 3.0L Lower Units
13 Splines
20, 25, and 30 inch Shafts.
If you have an 8 Spline drive shaft you will need to buy the stub shaft unit
and purchase an upper driveshaft from an OE dealer.
20" 45-824114A 1
25" 45-823901A 1
30" 45-824115A 1 (This item is no longer available from the OE. You will need to source a used one, or fix your old drive.)
If you have a 13 spline two piece shaft just purchase the appropriate
one piece shaft from the drop down box above.

The SEI 216 gear cases are supplied with the correct water tube coupling for units with a serial number of OG438000 and higher. If your unit has a lower serial number, you will need to use your old water coupling or purchase the correct part (SEI part number 96-116-12K).
