READ FULL ITEM DESCRIPTION BEFORE YOU BUY. Honda 30 HP 4 stroke outboard lower unit gear case CORE for parts or repair the reason we listed it as four parts or repair is because I know nothing about this engine I acquired it I think it had crankcase issues I have no idea how many hours this engine had on it I don't know anything about its history or origins I can tell you that I put a socket on the end of the propeller shaft and it is not froze up it does turn as you can see the very bottom fin is damaged looks like it in its day has hit the bottom a few times so there's a piece missing from the lower fin other the that There is no other structural damage the casing looks to be in good condition and I don't see any cracks or damage the shaft looks good it's not bent the splines look good but you won't know until you take it apart you never know this unit may be good just like it is but I don't know so I'm selling it under the presumption that it may need work or probably needs work use your discretion. This is a used part it's over 20 years old it's in less than perfect condition it shows wear and tear it may need work it's being sold as is for parts or repair. Look closely at all pics make sure this is the right part before you buy feel free to ask questions don't have me ship it then start asking me questions all sales are FINAL NO returns NO warranties NO cancellations NO exceptions.

I don't do returns I do stand behind my parts but I will not honor complaints because you changed your mind or you bought the wrong part or you got a deal somewhere else you bought it it's yours.if you have a problem before you leave negative feedback or you open a dispute with eBay please send me a polite detailed message with pics please be polite I will not respond or tolerate rude or disrespectful messages hey this part is no good give me my money back is not going to work it's being sold as is until you take it apart you just don't know so that's how I'm selling it under the presumption that if it needs more work then you anticipate that's just the chance you take that's why it's being sold as a core part but if I do find you have a valid complaint and or problem I will address it promptly fairly and within reason and thank you for taking the time to read my item description.
