1984 Ranger 395v I/O Restoration

I have an '84 395v I/O that is going to need some work on the boat and the trailer. I'm picking up the boat from being in storage the past year and a half (It is shrink wrapped). I intend to leave the wrap on it but I am sure the trailer will require some work in order to make a 1600 mile journey. I anticipate the hubs are not road worthy enough for the trip and I am thinking of pulling them, repacking, and tossing on a bearing buddy and bra before towing. Since I don't have the trailer with me I need to know if anyone knows for certain the hub bore so I can order in advance. Thank you!
