So I found a ’58 Johnson Sea Horse 18 for sale locally. It probably hasn’t run in a while. Are they hard to get back up running? Is $180 a reasonable price.
Sounds reasonable. I just paid $150 for a 1958 18 Johnson with gas tank that came with the age-old story "Ran good last time out 10 years ago". Like the one you found, Compression feels good when I pull it over. If the motor you found hasn’t been run for a really long time, it will probably need a water pump impeller and if the magneto coils are original, they will be bad, but not hard to replace and very available, as that same coil was still used up into the 1990s on the 2 HP.
Be sure you get the dual line pressure-gas tank with it – they can sell for $50 to $100 alone.
