Did a Texas winterizing today. Drain the block manifolds heater ect. When I got under the boat to put protecting lube on the shaft I noticed the rubber grommet where the shaft enters the hull was worn funny. Seem the previous owner also put silicone around it too. Any suggestion or tips would be great. Thanks in advance.

Looks like strut may be bent to starboard side. Any vibration while underway?

Oh, that's not good.

The propshaft isn't supposed to touch the sides of the shaft log. Yours looks like it's rubbed hard enough and long enough to raise a burr on the plate - hopefully that's just the sealant bunching up.

I'm guessing the PO bent the strut enough to have a water leak from the stuffing box, noticed a bunch of water coming in around the propshaft, and smeared sealant on the outside to stop the leak. Which, I'm sure, it didn't do.

I'd look at this thread (http://www.mastercraft.com/teamtalk/showthread.php?t=54362), starting at around post #135.

It may just need an alignment lifting the rear of your engine ,your drive shaft is probably damaged or has a groove ground in it also
I've seen people drop the rear of the motor to cover up a vibration by biding up driveshaft a bit before selling a boat
your strut bushings are probably toast also.
Or strut is bent like posted earlier.

More pictures. of cutlass bearings, strut and prop. Best shot for prop from directly behind boat.

I would repair it this winter.

The previous owner didn't even know what a stuffing box was. Wonder if the silicone was his attempt to stop the normal drip. The shaft doesn't look bent or does it vibrate. The bushings are still good I will get more pics shortly

Try the easy stuff first: Align your engine. Takes nothing more than a wrech, feeler gauge, and some time. Looks like you will need to replace the seal, but don't get too carried away without checking the easy stuff first.

More pics. Hope this help some. Any idea what this will cost to repair right and is it something that could do. I'm mechanically savvy. Lol

Not to imagine things but does it look like the rubber piece isn't centered right like its higher on the port side. Which would make it wear that way. This boat only has 329 hours but its 16 years old. ONly reason I question it is there is not vibration or is the shaft in a bind on the strut bushing

If I'm right. That is right the rudder is ofcenter. I thought it was due to the propellor walk when going forward. So you don't need to turn it al the time.

On our 2012 X2 it is also out of center, or was it the strut and prop :s.
Someone correct me if I'm wrong.

If you're "mechanically savvy" as you put it, you can fix this. Unbolt the coupler on the shaft from the transmission coupler. As soon as you do, if the shaft was in a bind due to the engine being out of alignment, it will quickly spring away. If so, I believe that is your answer to why the seal is damaged.

If the shaft itself is bent, I would expect the strut bushing to be worn as well...from your pictures, that doesn't appear to be the case.

Remove your prop, then unbolt the shaft coupler from the end of the shaft (where it hooks to the transmission). This should allow your shaft to slide out and past your rudder, so you can replace the seal. Hopefully you have enough clearance to not have to lift the boat to remove the shaft completely.

If you're out of alignment, careful adjustments on the engine mounts should get you back on track.

Definitely bent to port. End of prop shaft s/b starboard of rudder. Shaft may be straight if you don't have vibration - but needs to be checked with a run out gauge.

If strut just bent - about $250 if you do it yourself. - upwards of $700 if new shaft needed more if shaft log damaged. if it's just rubbing no big deal - that issue will go away when everything is true.

Removing the strut takes a little effort. I will look for the thread - but after removing fasteners a little heat and a ratcheting strap you will get it off.

My rudder is mounted off center also the wheel is turned. Youre saying its bent to Port??

one more question... I understand how the shaft seal works and but what is the rubber piece that has the silicone on it that is worn called? The piece with that goes into the shaft log. Sorry i has used the search button just cant find it,
