SEI MARINE PRODUCTS - SE306 2.25:1 V4 Gear Ratio

Engine

Fits V4 Johnson/Evinrude with the 4-3/4 bullet diameter V6 case.
Uses the Ocean Pro style water intakes and you will need to use a 1991 or newer prop thrust washer.
Does not include upper driveshaft. If your old unit has a one piece shaft you will need to purchase an upper driveshaft. We use the newer style stubshaft with a clip. If your upper shaft is not the newer style you will need to replace it.
Our unit does not include a water pump or the shift shaft. You will need to install your old ones and adjust the shift shaft.
Replaces OE #:0438051. These lower units typically ship within 24-48 hours and you may paint the unit to match your outboard.

All of our lower units come with a three year fault-free warranty. They are manufactured in Oldsmar, FL, built up to OEM specifications and they are an affordable, high quality alternative.
