3700 scr newbie

[moconnor]

Good morning, We are scheduled to close on a 2000 3700 scr this week and having her shipped here to Cincy from FL. I'll need to change the anodes 1st thing since it's going from salt to fresh.
Anyone know what size the shafts are? 7.4 mpi gas. I forgot to measure when I was there inspecting the boat.

thanks in advance
