One thing leads to another. this started as a starter issue.
Thanks Chrisis: and Swampu: for giving me more work. As stated. As long as the tranny is off may as well do the rear seal.

Not a big job if you have the right tool. I don't, and can't seem to find one to rent.
The Cat dealer will do it for about $800.00 on a special trip.
$200.00 if they have to go to the harbor anyway.
The tool is around $350.00.
Still looking for the tool. I can't see buying a use one time tool.
So she may set for a week or so.
Ticks me off the Salmon and Halibut are running.

I plan on taking lots of pics as I do this repair.
Watch for it.

This is what I could see looking into the port for the starter.
The first is what it is supposed to look like.
The second is what I could see after using a screw driver and rotating the fly wheel.

The Aluminum was breaking off in chunks and getting into the starter.

Third is a little better shot to the left you can see where a crack is develkoping. Top center is where it has broken off.

Just a follow up. The mechanic just left and it took him about an hour to block the engine, unbolt the coupler, drain the water and fluids and get the transmission out of the boat. No problems at all with the dripless, it slid back to remove the transmission and slid forward again to sit where it was until the tranny goes back in. Never leaked a drop. I don't have the equipment or the desire to do this project which is why the mechanic is doing it. We are also replacing the damper plate and engine mounts while all of this is being done. I have done all of this myself in the past but the back doesn't like it much anymore. Now it needs to be checked over, new seals and reinstalled. Chuck

I have no desire to do this job either, but finding as mechanic in my area is like finding a fishy smell you know it is there but tracking one down ain't easy.

A question on the rear main seal. How do you tell if it is leaking or not. I think I can see the seal.Not sure. Will I have to remove the Fly wheel housing to inspect it? The fly wheel is off and all I see is rusty dust.

Has anyone had to replace the rubber blocks on a Twin Disc tranny on a Cat 3208?
I have the model 506

These look Ok but when I took one off and pinched it I could see some small cracks.

They should be replaced whenever the gear is pulled. They just slip off the "tooth" and new ones slip back on.

Thanks Rick,
Someone suggested the same about the rear seal.
Luck would have it it is not leaking.
Really hard to find the tool to replace it.
The only one I could find was in Fairbanks. The local Cat dealer had the other one and wouldn't let it out of there sight.

Ahh, boating or working on boats in Alaska.
Do it yourself because there is no one you can hire to get it done.

Ah, so ... may as well wait until the seal starts leaking then.

Why not buy the tool and then rent it out if they are so scarce up your way? That might be cheaper than having to repeat the entire process in a year or two.

Well unless I want to have the boat out of service for the rest of our short summer.
I'm gonna have to.

I'm 3 weeks out for Cat to come to the boat and a good 4 weeks for the tool to get back from Fairbanks.

It is not leaking now.

I have now the knowledge and equipment to pull the tranny and replace it at a future date.

So that's it. I will wait till it starts leaking.

dude my trannys been in the shop since your thread started. I almost don't want it back because I will no doubt be broke when the bill is due,,,,, but hurricane season is here and I've got to get this thing going. No offence but the inside of that thing looks not so shiny. What gives, water leak, underwater? Mine burned up and it was shiny new looking, just broken. Good luck. Paul

Under water.
She sank in 92 down to her lines at the dock.
The motor was pickled and the top end rebuilt.
That is why I have been having this problem.
sometimes it is remarkable the darn thing still runs at all.

Does Twin Disc still supply customer support, i.e., parts, for that transmission? I have 26 year old Volvo transmissions and am SOL for parts.

Well, I rigged a sawhorse and used a come-along to lower the tranny back into the ER.
A little trouble getting things to line up but the suggestion from Rick B and Marin to use guide bolts worked like a charm.

I use longer bolts to get the bottom of the transmission to suck in as I had to draw the new rubber blocks into there slots on the drive ring.

Once the tranny was in the rest was just bolting everything back up.

Turned the key and no more starter problems. It also seems to have gotten rid of my vibration problem.

All in all a sucessful reinstall.
I forgot my camera so no pics.

Thanks for all the advice.
