Re: 1958 10hp Evinrude
I have a '58 10 hp LU on my bench right now with that bushing shot (actually I think 2 of them!). Yep, you need a new LU housing. I have heard that a machine shop can change it but it costs a fortune. Too bad. And that pinion gear is worth around $130 at the dealer. Get a used LU is your best bet. Also as an FYI, the LU in 58 is a lot wimpier than the 57's and earlier and tended to be a crappy LU.
