Upgrade Your Vessel with the SEI SE228 Lower Unit

Reliability on the water is non-negotiable for every boater. Therefore, the SEI SE228 Lower Unit is a top choice for those needing a counter-rotation gearcase. This unit is designed to replace original equipment on several popular engine models. Specifically, it works with 3.0L V6, 2.6L I6, and 1.7L I4 engines. By choosing a high-quality aftermarket solution from Macomb Marine Parts, you ensure your boat remains ready for action.

Broad Compatibility for Verado and V6 Engines

One of the best features of the SEI 90-228 is its versatility. First of all, it fits the 3.0 Liter V6 Two-Stroke engines with a 13-spline driveshaft. In addition, it is compatible with the 2.6 Liter Inline 6 Verado models ranging from 200 to 300 horsepower. Furthermore, it serves as a replacement for the 1.7 Liter Inline 4 Verado engines. Because this unit focuses on "Verado Style" gearcases, it provides a precise fit for standard 4.8 torpedo units. However, always verify that your engine does not require the larger 5.44 torpedo before ordering.

The SE228 (Replaces some C.R. 3.0L V6, 2.6L I6 and 1.7L I4) is built to last in harsh marine environments. Since it features counter-rotation, it is perfect for dual-engine setups.

Frequently Asked Questions

Does the SE228 fit the newer V6 and V8 Verado engines?

No, this unit is specifically for the Inline-4 and Inline-6 Verado engines. The newer V6 and V8 Verado models use different gearcases that are not compatible with the SE228.

What is a "counter-rotation" lower unit?

A counter-rotation unit is designed for boats with two engines. It rotates the propeller in the opposite direction of the standard unit to balance the boat's steering and torque.

Do I need to buy a separate water pump for this unit?

Generally, SEI complete lower units come with a water pump already installed. However, it is always wise to verify the specific kit contents on our product page.

How do I verify my spline count?

You should count the teeth on the top of your vertical driveshaft. The SE228 for 3.0L V6 engines typically uses a 13-spline shaft, while the 2.6L and 1.7L Verado versions use a 20-spline shaft.
