There isn't a core plug for the cooling system on the 130 blocks.

Re: AQ130A on glastron

Maybe this is a wild ***** guess, and it doesn't address the vibration issue, but I am bothered by the fact that it only leaks when the engine is OFF. Couldn't this be a backpressure issue and a hole in the exhaust pip below the water line. it might look like it's coming from the bell housing.

I think it probably IS the drive bellows and bearings, but this was buggin' me so I had to say it.

Re: AQ130A on glastron

If it was the exhaust pipe, it has water in it when the engine is not running. When running it has less water, and more exhaust.

Back to the bellows. When it leaks and destroys the bearings in the bellhousing, when it's running, it wobbles. The seal on the engine side of the bellhousing can't seal against a wobbling shaft and water comes in. When it stops running the shaft sets there and the seal keeps the water out.
It won't be a lot of water, it has to pass 2 seperate seals, but when it vibrates and wobbles it does leak.

No, I agree it probably is the bellows but what you just said about the exhaust is EXACTLY what I was referring to. He says it only leaks when it's OFF. When he runs the enigne it doesn't leak. The exhaust keeps the water out. When he shuts down the pipe fills up and it leaks.

It was this very behavior that me wonder..

Who knows, with the spinning ujoints, it may push the water out of the bellows. But look at the picture, his arrow is way past the exhaust. It's in the bellhousing.

I know.. I saw that.. it was just the odd behavior of only leaking at rest that made me wonder.

I'll go away ;)

Re: AQ130A on glastron

Don't go buying any parts till you get it apart and see what you have. You may need a complete bellhousing and shaft.
First thing to do is pull the upper gear box and see if you have water in the bellows. If no water, then something else is wrong and needs to be found before you take it all apart.

Hi Graham;-)
As I wrote yesterday, control the valves and the ignition (you can start the engine outside the boat too). Does the oil look milky? Oil pan gasket all right?

Have seen a few of them that people just keep running that had the bellhousing all beat up so it wouldn't even hold new bearings. And no an car bellhousing will not work. Completely different setup.
Basically, take it apart and see EXACTLY what you need before ordering anything.

i dont suppose this will help on my quest but when thinking about the bellhousing bearings there was quite a bit of knocking coming from that area when in gear whilst on the water but when in gear on a hose there was no noise,also when engine running(not in gear) and leg trimmed all the way up the ujoint knocked a bit but stopped when leg was down

Re: AQ130A on glastron

No water, no load on the shaft, sounds about right. And NEVER run it all the way up. The ujoints WILL contact the housing. That could be the cause of the problem to start with.

Re: AQ130A on glastron

well lets carry on this saga
took upper unit off today and heres what i found
bell housing DESTROYED
bearings DESTROYED
ujoint worn out
ujoint bellows ripped
so all in all don s you were 100% correct in what you thought
there is a guy i know that refurbs ujoints for ?100 and he has a good secondhand bell housing with new bearings and seals for ?200 so im gonna go with that
the exhaust bellows are fine but there is a thinner bellows just below to the right of the ujoint bellows which is a bit cracked what bellows is this????
and thanks everyone especially Don S and Larrs for all that info
hopefully the vibrations will cease to be once all done

Re: AQ130A on glastron

Hi Graham!

Are you talking about the bellows which is connected to that muff?
That is the cooling water hose.

Regards,
Lars

PS: I am pleased to hear that you have found your malfunction!
