I've never heard of gear oil that thin ..... it would be like water if it was even available. 
I suspect that 20 - 30 is engine oil but suggest you check the manual (paper or online) for more information.

My old Volvo MD2B used to use standard engine oil in the gearbox.
You won't get that oil from Halfords but most Auto shops will sell something suitable. Typically used for classic cars or agricultural machinery (at least that would be SAE20 or SAE30 that I guess would do

OK, as the manual says, the oil is just a standard monograde SAE20 or SAE30 engine oil.
Halfords probably won't be much use but a motor factors probably will or just eBay it https://www.ebay.co.uk/itm/Morris-SAE-30-Classic-Oil-5L-/372110554042

My gearbox uses the same oil as the engine (Volvo MD22).

There is no such thing as SAE 20/30 oil. Your Yanmar plate (and the Bukh manual) means either SAE 20 or 30 dependent upon temperature. My Yanmar KM3P gearbox takes 15w-40 engine oil, engine date about 2000. Is yours older or newer than that? Not much equipment calls for monogrades now unless there is a good reason for it.

Not sure how that is helpful when he clearly has a Yanmar engine and Kanzaki gearbox. Many gearboxes do not use the same oil as the engine.

Have a look on Amazon. My gearbox (Kanzaki/Carl Hurth) specifies Dexron II or equivalent and I was able to find it on Amazon at a reasonable price.

The manual for the Yanmar JH series engines says this about the transmission oil:
Hi VicS,
I'm not quite sure of your point in reply to my post.
Dexron II is specified for my boat and I have the manual. I used it as an example for the OP of an oil I expected to be difficult to get but found easily on Amazon. I wasn't recommending he used what I use as he doesn't have the same gearbox.

Isn't it just the same as SAE30 4 stroke lawnmower oil?

Austin Sevens use engine oil in their gearboxes, straight mineral SAE30. It is available and cheap.
