S4010106.JPG S4010107.JPG S4010108.JPG S4010109.JPG Is this a commercial lower unit? It came off of a houseboat and has a larger diameter than normal and the bullet is more rounded in the front.

No, not commercial, but it does look like it's not the original lower unit. The green paint looks a bit like 1970s Johnson, and the vertical trailing edge of the skeg is also 1970s. The 1980s models had a swept back skeg. Bullet diameter was the same.

I am thinking it is a 1977 lower unit. The 1978 had the swept skeg and it shifts correctly which a 76 and earlier won't. Will the guts from the 77 fit in the newer gearcase? Thank you very much for the reply.

Off the top of my head, I can't see why they wouldn't. Possible I'm missing something, but it might be worth a try...
