Replacing a prop on my Volvo 290 dp. Going back in with a b6. Found a nice spool of high quality fishing line wrapped around the prop shaft.

Need to find the seal or gasket that goes on the prop shaft, between the first and second props. Where is the best place to buy one. Does anyone know the part number for the kit?

attached is a picture of the prop that I am replacing. Works great as a depth sounder.

Me thinks it's a bushing not a gasket or seal

Thank you for the part number. Didn’t know that it was called a bushing.

The fishing line worked everything over. First time for everything.

Don't hold me to it.
Just showing you what the parts schematic shows

One more pic. It still has the tangled mono on it but you can see the size. Starting to wonder if it is just a bunch of melted mono.

Looks like just a bunch of melted mono. The seal would be black with metal impregnated. There’s actually two back to back seals on each prop shaft

Are you talking about the seal for the inner propshaft? If so, there are two, you will need to remove the bearing carrier and outer shaft, so you would also replace the bearing carrier O rings, and outer shaft seals as well.

between the first and second props.

brendanm

Yeah, that's where the inner prop shaft seals are.

Thalasso

He said he was looking for the piece that goes between the props. Not seals. There is a spacer (thrust ring) that goes between them
Will depend on which props he is using


thrust ring superseded from a rope cutter that is now discontinued

I see. Thought op was just confused on terminology. I'd personally be worried about the seals with that much line flapping about in there.

Thalasso

Don't know what props he had but he mentioned going back to B6's. He will need the right spacer for that

Tumble Weed

I am confused on the terminology. I am going to take some more pictures and make a more detailed post. I appreciate places like tht, where members readily help each other out.

Post some more pics of the part. That looks like the original fishing line cutter (discontinued and replaced by thrust washer) that goes between the props and over the forward prop nut. If the fishing line cut a shaft seal you will probably have gear oil leaking around the seal. That can cause bad things to happen.
