" I recently purchased a used OMC Stern Drive Lower Unit. Originally, the seller said it was an OMC 400 then later said it came off from a 4.3 Litre, which is what I need. The only numbers I can find on the Lower Unit are 333186 and D2. Any help in identifying what lower unit this is and application would be greatly appreciated.
Thanks,
David "

" I shure if it came of a 4.3 its got to be a 800 outdrive, a 400 has a smaller proppeler shaft and is rated for a less horse power normaly on a 4 Cyl. hope this helps. "

" If the prop shaft housing is the same diameter as the one you need ... you got the right size. The 400 is much smaller and obviously not the right one. However, depending on the year and exact model, it still might not be exactly right. "
