One of the reasons to have a dripless is so if the shaft gets bent/tweaked it will still hold a seal as the gland moves up and down. Also a long shaft over time tend to droop, and a shaft does not have to be perfectly align which is more based on the RPM and load. The Eagle shaft move up and down enough that you can see the gland move, but itís a slow turning, max 500 rpm, 2 1/2Ē and 11 ft long, however the tail ends are right one.
We run the Eagle bend shaft in the shop on a lath up to 3,000 rpm with no vibration. Also the shop would not guaranty if they machined the shaft that it would be any better from end to end, and over time it would droop again. So been running it for 15+ years with NO oil or water leaks. So before you spend all kinds of money evaluate if itís really necessary. I am not saying you should not try to correct, but at least evaluate if itís worth the time and money.
I will say the alignment should be with the boat in the water after a couple of days by some one that know how!
