Description
SE218 Replaces most Mercury 3.0L Lower Units (SN 1B504989 and below). Does not replace the Torque Master, Torque Master 2, or the Sport Master. 25" shaft with 1.62 ratio.
Available with a 25 or 30 inch (13 spline) one-piece drive shaft.
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:
- 25" —
45-823901A 1 - 30" —
45-824115A 1(no longer available from the OE; you will need to source a used one or repair your old drive)
If you have a 13-spline two-piece shaft, simply buy the appropriate one-piece shaft from the drop-down box above.
The SEI 218 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 96-116-12K).
