I broke the "skeg" (I think that what fin beneath the prop is called) I am told that it can't be repaired. I actually broke enough to see the gearing inside. I have a "93 Chris Craft 228 with a 7.4 ltr king cobra and a volvo outdrive. I found another outdrive that I am told is from a 460 king cobra. I am trying to find out the year and make. Would the two lower units possibly be interchangable? I would like to just swap out my good internals to the new housing. I am VERY new to the boating life and I am already breaking my new purchase. Any help would be greatly appreciated!! Thanks
