The tyre coupling is like a heavy duty rubber wheelbarrow wheel which is bolted between and seperates two sides of the prop, it cushions the prop when the gearbox is put in forward or reverse. I will try bolting down the plummers block (everything seemed aligned before the engine was removed). Then disconnect the shaft from the reduction box and see whether the bolt holes line up. Thanks for the info Tony.

I had my lister sr2 engine removed, it turned out to be a problem with the reduction unit, it had a hole in the casing. It's bolted directly on to steel bearers, no rubber mounts just spacers, which I left in situ when the engine was removed. I fitted a new half-tyre rubber coupling, the old one was shot and a Marine engineer fitted the replacement reduction unit and refitted the engine. I've now got vibration (slight wobble) on the prop and the plummer block is noisy. The noise goes when I loosen the plummer block. It appears to be higher above it's mounting spot than the thickness of it's steel spacers, so the plummer seems to me to be pulling the prop downwards when it's bolted down. I'm wondering whether there is possible engine misalignment and whether raising the plummer to eliminate the noise would help any?

Well done Phylis, it's good to know you tried to help a creature in distress.
