3.0 belt pulley rubbing mount?

So after reading a bunch of threads on replacing the alternator belt I decided I'd tackle mine today. It's been squealing a bit and has a bunch of slack despite the alternator being at the end of the adjustment range. (doesn't look like previous owner used the right size or it's way overstretched). Upon inspection of the pulleys and work to be done I noticed that the main belt pulley for the steering/alternator is actually rubbing on the large washer for the mount (see pic). I'm assuming this can't be correct. Despite the fact that they've been rubbing, I never heard it or noticed until now (despite having my face down in the bilge yesterday while running). Can something be adjusted here without affecting the alignment? (boat was aligned by marina last spring, I don't have the tools required to re-align)
I don't see any way to get the new alternator belt in without removing the pulley despite reading threads that say I shouldn't have to - I'm guessing that if all were as it should be, not only would these not be rubbing, but there'd be enough clearance between the pulley and this washer to fit a belt. In it's current state, I'm not even positive I can remove the pulley!!

No pics, and removing pulley doesn't make sense.

:facepalm: here's the pic

With no clearance between these 2, how would I get a belt on without removing the pulley? To get a belt on, it looks like the engine would have to be sitting at least 1/2" higher than it is??

Something is terribly wrong there. You need to find out why its so low,rotten stringers,rotten transom,bad mount's? Really bad alignment??

Anything specific to look for, for rotting? not seeing anything that's jumping out to me, the alignment was done by a marina last year after a gimbal bearing/full bellows job. Used it all last season and took a couple laps around the lake yesterday, didn't hear any signs of a really bad alignment (I assume I'd hear something with the u-joint??)
If it weren't alignment and were something rotting, any tell tale signs to look for? Nothing's jumping out at me as rotting..

Is that the water pump in the picture? If so is there any play in and out on the shaft? I just did my 3.0 timing cover last week. I put a stack of wood under the oil pan, then used a lever to pry the engine up 1/4" and add one more piece of wood to the stack. I was then able to easily remove the front mount and belts for inspection.

How about the mount itself,it could be bad,take a long prybar and try to move it up/around for any play delaminaed rubber ect,

I'll give it a shot and see - is it safe to assume that adjusting that long bolt that would raise the engine would throw off the alignment?

It most certainly would, because that is how you adjust the alignment on a 3.0.

Re: 3.0 belt pulley rubbing mount?

Well it's (sort of) figured out now, thx for the tips..

I did have to remove the pulley as well as the spacer, and once the spacer was out - the engine dropped about 1/2". I used a car scissor jack under the alternator bracket to prop her back upso I could get the spacer bolts back in and tightened it with the pulley about 1/4" above the alignment bolt thing so it's not rubbing anymore..

Re: 3.0 belt pulley rubbing mount?

Is there a lot of belt material all over the front of the engine?

If that pulley is as rusty in the vee as it is on the outside then I think I know why a belt would wear and slip after a very short time, just sayin.
