Hello team Johnson, glad to join this forum I'm on iboats slot too, my lower unit went out and I found another one of same HP on eBay for 120.00 but now I noticed the e bay one has a set screw and mine doesn't and driveshaft is a little thicker just before water pump but is same length at 21in and 4splined, I have a 1970 Johnson 60hp,any help here would be awesome, thank you all here.
