MerCruiser SEI SE106 91-104-01AK 1.94 4cyl 20-24 3.0L Upper Gear Set Aftermarket Lower Unit The pins are the same

The pins are the same dimension-wise the only difference is that it took the greasable needle bearing lower pin bushing rather than the nylon one

This is not returnable

Strong / Flexible - We have re-designed these to be just as flexible as the originals but also beefed up the areas where they tend to break after many years of exposure to high temperatures and constant abuse

but there should be some usable parts after a bit of cleaning
