For shimming, I have found these to work great even though I have mentioned using flat washers.



They are easy to use on older non recessed struts. With newer recessed struts, you will need to bend the tab on the end.

McMaster has them in stainless.

When aligning it, am I checking to see where it is centered from the picture I posted or where the shaft goes through the hull. Because, the pic I posted shows it being pretty evenly spaced by the eye.

I am getting to the point where I might damage the hose trying to remove the packing nut from the tube. Is the packing nut supposed to be removable or is it glued to the packing nut? It also does not want to slide away from the hull. I pried the crap out of it and got no where.

I realize if I damage the hose, I will be pulling the shaft off the boat to replace it and this project is already a handful.

Can someone tell me if I am suppose to take the nut apart from the hose or if this is one unit and I need to pull it directly from where it meets the hull?

I had to reinstall my prop the other day and was able to get a good look at the shaft alignment through the hull just by crawling under the boat and shining a light at the point of entry.

I dread having to re-do the packing glad as I am sure I would run into the same problem with the hose.

Also, I noticed you were not able to get left to right movement for aligning the couplers. Have you looked into how the v-drive is supposed to be aligned? I have the same set up and the v-drive was bolted down to the mounting brackets. There are left to right and up and down adjustment screws on the v-drive mounting brackets.

You should be able to pull the hose from the log while leaving the other end attached to the packing gland. Then you'll see where the shaft is in the log. Try twisting it to break it free.

Yeah, I downloaded the manual from Walters. I loosened up all the bolts holding the v-drive in place as they suggest and moved the engine/vdrive around for 2 days while it was loose and no luck lining it up.


Is there a particular dripless packing that everyone usually goes with? I wasnt sure if OJ and the one from Correct Craft are the same. I only ask because I think I am about to destroy the hose I have trying to remove the packing nut and if I am going to go through the trouble, then I might as well do it right.

Bingo... It can be very tight, but it didn't grow there.

I *believe* the optional dripless from correct craft is the Oj. Great idea to add it if you've got the shaft out, since you have a v-drive.

Finally got the hose off using a non correctcraftfan approved vise grip.

Here is a picture of the shaft in the log. It looks to be centered ok. It is not perfect, but it is definetly not touching on the sides.

I checked the rear of the shaft for straightness and it is not bent there either.

Where would you go from here?

Would you even mess with moving the strut? Where can I buy the zinc footballs spoke of earlier?

Is the shaft aligned in the strut where youre showing it (spins easily by hand)? Or is that resting under its own weight? Or are the couplers still connected (not yet aligned?)?

If thats where it spins freely in the strut, then youre probably close enough.

You might want to lube the bushing or it might feel tight no matter where the shaft is.

I have been pouring soapy water on the cutlass before spinning it. Spins easily that way not coupled, coupled is a bit tougher. I am going to take a stab at getting the shaft perfectly even on the log by shimming the strut. I already have it all apart, so might as well get it right.

I spoke with a local mechanic who told me .010 difference was acceptable. I dont think he has been on this forum LOL. I know that is not acceptable either, so a few more days of messing with this thing and it should be right.

If the above picture shows the shaft as its aligned to the strut (not sitting under its own weight) and it has more than 1/8" clearance to the log all around, I would personally not mess with it. Align the motor to it.

If the strut were already off and shaft apart, thats another story... but if you'll be pulling the strut off and resealing it, not to mention pressing the coupler off the shaft to get it apart, thats not a fun job.

Maybe if you needed to replace the strut bushings at the same time, it would be worth considering. Or if youre a glutton for un-fun projects and have some free time on your hands, ha. Definitely consider replacing the strut bushings while you have the strut off, if you decide to go down that road.

Does he rebuild Walters V drives??? It is NOT acceptable are there would be a rather large chance of damaging the V drive.

If the forward section of shaft isn't "hanging" with it's own weight, then Tim's statement below is correct.

The last picture I took showed the shaft pretty centered. It was attached to the vdrive and was ok to turn, but not as light as I wanted it to be and I was unable to get to the .003. So, I started putting washers in different spots on the strut. After playing with it for a while, I had the shaft centered by placing a 3/8" washer in the front and rear of the port side of the strut but I didn't like the way it lined up with the rudder. I didn't try to match the couplers up at that point though. But, the shaft seemed to be centered in the tube.

So, I took all the washers out and the shaft wants to have very little clearance on the hull near the vdrive end port side. The strut does not appear to be bent. But, something must not be right if it will not lineup on its on without spacers?

I have checked the shaft on both the coupler side and the prop side and it appears to be straight. Something is not right somewhere as I have to put pressure on the shaft to center it and I am leaning towards the strut. Is there somewhere that you can send a strut to check for straightness?

I think I've read where the struts are sometimes adjusted on the boat during initial set-up. That is to say that a rail straight strut may not be necessary.

Alignment of the strut has nothing to do with the rudder. The strut needs to be aligned with the hull hole/log.

Again, forget the rudder. Align the strut to the hull log.

Ok, I will disregard the rudder and see if it lines up at the coupler now. I will let you guys know how it goes later today.

Agree with Pete about the rudder- ignore it.

With comments like this, I still question whether you understand the concept of alignment or not. Go back and read the comments in this thread.

You need to do these steps in order!
1. Find where the shaft turns freely in the strut. Support the shaft so it stays in this position.
2. Look at where the shaft goes through the log (after doing step #1). If its close enough to being centered, move on. If its rubbing or close to it, then the strut needs to be adjusted- either moved within its mounting holes, shimmed, or straightened.
3. Once you have aligned the strut and log, you can start to move the powertrain to line up with the shaft. Again, you are moving the powertrain to meet the shaft in the position it sits after step #1.

It sounds like you are moving the shaft to a position within the log, and THEN determining whether it is "aligned enough" in the strut... and that is backasswards. That would be a recipe for misaligment, as even if you can get the couplers to mate nicely, if the shaft is in the wrong place to begin with, you havent accomplished anything.

While I am not the best communicator and usually post while I am frustrated, I do understand the concept.

I have made a lot of rash decisions in this project and posted things I should have thought about before just posting. I didn't have a prop puller, so I was trying to shim the strut with the prop on the boat. I finally decided to go out and borrow another prop puller and pull the prop.

After pulling the prop I removed the strut and soon realized why my problem has been so bad. While you couldn't tell it by looking at the back of the strut, the strut was bent and twisted. The cutlass is showing a little wear as well.(dryrot- 15 yrs old.)So, I am ordering another strut, I know you can bend struts back and shim them to fit, but me being a rookie, I want to know that the part is right from the start. I am ordering a new one when everyone opens back up after the hollidays.


Thanks for everyone's help and patience. Happy Hollidays
I am also going to pull the shaft and put a dripless shaft packing in it. I am leaning to the PSS over the OJ (any recommendations would be great) I am sending the shaft out to make sure it is straight and having it matched up with a new coupler by the guys down at General propeller down in FL. After that, it should be all good and I can align it with everything known to be straight. May be overkill, but I don't want to mess with this again.

If your strut looks that bad to the naked eye, Id bet good money your shaft is bent too. Rather than spend a dime on R&Ring the old shaft, Id highly recommend a new ARE dual taper from SkiDIM.

That is a good thought. By the time I shipped the thing down there and bought a new coupler, I would only be saving a couple hundred dollars. I just need to quit being cheap and pull the trigger on the A.R.E

Chad,
Don't count on the new strut to match. They are not a precision machined item so the new one may require shimming.

Thanks Pete, I was looking at the link you sent me earlier about shims. Is there a particular thickness you buy or do I just need to buy a bunch of different widths? Wasnt sure is there was a general order. My boat strut is recessed in the hull. I know you said to bend the tab to make the shim you pictured work, didnt know if you preffered a different one if the only boat you are aligning is recessed. I realize for you with as many boats as you align, it is probably easier to buy just the one type of shim.

The width of the shim is governed by the slot with for the bolt size. I would get .010", .020" and some .030" thicknesses.
