Advice on the condition of these gears

[fleetwin]

Well, that is sure peculiar….Really looks like it was cast that way….There is no problem if it pressure tests OK, but I can’t imagine it does, there must be an oil leak in that spot. Did you drain the oil? Was there any oil inside the gearcase? Any water?
The upper/lower portions of the gearcase are a matched set, so the entire assembly should be replaced if that flaw has created a water leak….
So, it is kind of hard to advise on what to do…I would surely give the seller a call after inspecting the gear lube. If you decide to keep it even though that area has created a leak, I would surely disassemble it to ensure the innards are OK….The gears/shafts may be in the same shape as what you currently have. You could transfer the innards into your case, provided your case is OK….
PS One of your pictures looks like you already have the gearcase apart, is this the case? If so, post some pictures of the skeg mating surface so we will know if the seal surface has been compromised….

I’ve seen that happen when someone runs a prop with a spun hub. The outer hub gets pushed forward and rubs against the housing, taking material with it. Won’t really affect anything – your new unit will work fine. If it really bothers you, stick the innards from your new unit into your old housing.

Brand new oil, no water. The gear case had work done to it and then sat unused for a few years. The dissembled gear case was originally on my motor.

I suppose I’ll try running it before making any decisions, my concern is the gap might make a good spot for weeds to get snagged.

With my original prop on there are less threads for the prop nut than with the prop that came with the unit. This is okay?

OK, well guess I was looking at the wrong thing….I’m with Scott, the damage you are referring to is from spun prop hub and won’t do any harm….If the oil is clean, I would use it just the way it is….
I was looking at that odd rounded notch where the spaghetti seal should be, but I guess this is normal, found it on another engine:

The ebay pictures clearly show that the spaghetti seal bends inward before that void in the casting, so ignore my previous post please…

Agree with Scott above, that prop is shot, from what I can see in the pics anyways, and likely did the damage you see to the case. If you didn’t pay much for it, swap the innards over to your case.
