vibration from prop???

I was able to swap props, the old one was a federal prop and I swapped an oj prop on. The boat still vibrates but it seems different. It vibrates badly under hard acceleration and gets really bad when I turn the boat with any throttle. I also noticed that when I put it in reverse and give it a little throttle it seems to chatter. This got me thinking that it could be the strut bearings. I removed the prop and shaft from the boat and I am still unsure of the cause. The shaft seems straight as an arrow but the finish looks bad where it rides in the strut. It is very shiny and has pit marks in the finish. Pulling the shaft out I noticed that it was kind of loose in the bearing but the bearing doesn't look worn. I am not 100 percent sure that the prop I swapped on is good. I got this prop from someone else and have never had it on a boat. I also noticed that the rudder is pretty loose in it's housing. Could the rudder be shaking around and causing the vibration? Anyone have a suggestion?

Man if the windshield shaked as you state I would look again at the shaft aft the strut and the propeller... mine did shake like that after hitting the river bottom, prop had no ding as the bottom was mud, but hard enough to bend the blade and the shaft... Had to return towed as the vibration was tremendous when trying to take off...It was aligned one month before this happened and the prop was also 2 weeks old...
I had all straightened again and then it ran very very smooth....
The prop should go away with no problem even with the rudder. Or unless your shaft its longer making the prop to be closer to the rudder...post a pics to see.
I use to redneck remove the prop with the wood chisels and rubber mallet method, I learned that ain´t the right way so I was planning on buying a bearing remover like the one u have.. I think It won´t be good... So I´ll fabricate one... No prop removers here....or if you get one they charge almost $150....Eric do you still have those pullers? Can you mail it to Buenos Aires Argentina?

feelings are mutual, but not lets talk about boats lol

I had a prop that was so slightly bent that it could only be seen on the workbench. Same with the shaft. I rolled it on a machined table and couldn't see any problem. I replaced it anyway and now it's smooth.

When you did you alignment, did you follow the proceedure to check for a bent shaft forward of the strut? (It's spelled out in Eric's alignment thread)

You do not need to pull the shaft to check if it's straight. You will need a dial indicator clamped to the strut. On the prop taper will check if the shaft is bent aft of the strut.

Please help. I finally got my boat in the water this weekend and it has a vibration under acceleration and at speeds of 10mph and up. This boat had the same vibration when I test drove three months ago but I was hoping it was shaft alignment. I am 99 percent sure the shaft is aligned properly so I am thinking the vibration is in the prop or shaft. I know eyeballing is never accurate but the shaft looks straight. I have a spare oj prop with the same pitch from another project that I want to try before I spend all that time pulling the shaft. The million dollar question is can I get the prop off with the rudder still in? I have three jaw pullers but none will fit with the rudder in the way. I don't stand a chance of getting the prop off without a puller, it is on there pretty good. Every thing looks good to the naked eye, the shaft looks straight and the prop doesn't have any dings from impact. Is it possible for a prop to go that far out of balance without any impact? I did notice that the prop on the boat is very sharp on the leading edges and the oj spare I have is much thicker on the edges of the blades. I am wondering if this is an original prop that is worn out and out of balance. The vibration is enough to make the windshield shake at 20-25 mph. Any advise would be greatly appreciated.
