I searched the clymer manual and found some specs for prop shaft runout....." if shaft runout is .005" or greater the shaft is bent" well.....don't know if this is an issue that needs to be addressed right away or can it wait a while? If i pull my lower off, I wonder how much $$$ it would cost to have a new shaft installed?? It may be bent slightly but it doesn't vibrate or anything like that.. It may be contributing to my prop blowout though? don't know. The next time i take the boat out, I will try to pay attention to which engine is cavitating.

anyone have a good used stock lower port side they would be willing to sell at a resonable price??

Why not just have it checked out? The prop shaft is about the easiest part to remove and replace. All the clearances are already set prior to shaft install. Just gotta set the carrier bearing preload when reinstalling the carrier crush sleeve/carrier retaining nut.

Been a few yrs since I rebuilt mine...is the .005 runout measured with the shaft installed and measured at the prop washer, or with the shaft removed and held between centers and measured at prop washer? Big difference

I measured it with the shaft installed, I set my indicator pointer just below the splines. .005" isn't alot, thought about putting the dial indiactor back on, getting a big pipe and trying to see if i can "tweak" it alittle bit. Its not out by much. This might be very minor and probably don't need to worry about it like the previous posting..?

I set up the dial indicator and measured it at the end of the splines, between the the splines and the bottom of the threads and i get .003" but get .005" at the bottom of the splines, I think im gonna run and not worry about it. I'll talk to my boat guy and see what he thinks. Has anyone put an indicator on a brand new shaft?? Does a new one have "0" runout??

You might also tweak the bearings doing that
