90-221-A30F - SE221 Lower Unit Mercury 300 HP Verado Inline 6, 4-stroke, 1.75:1, 30 inch, Standard Rotation

2.6 Liter – Inline 6 Cylinder – Four Stroke (20 spline drive shaft):
(SE 221-A20F, 221-A25F, 221-A30F, 221-B20F, 221-B25F AND 221-B30F)

These engines are the larger horsepower Verado models. The SE221 will work on these units from 200 horsepower to 300. The SE221 gearcase is the replacement for the 4.8 Torpedo units only. We do not offer a replacement for the 5.44 Torpedo. There are larger horsepower models of the Verado, but the SE221 is not to be used on them.

These units came originally with Torque Master, Sport Master or the 5.44 Torpedo lower units. Around 2019, Mercury came out with a family of V6 and V8 engines. Unfortunately, they decided to call them Verado. They do not have the same gearcases as the SE221. They also look the same as the SE221 from the outside.

Remember the SE221 fits only the inline engines, not the V6 and V8 engines.
