I have a sailing boat that's decking is marine ply, it's showing it's
age as it was left for three years uncovered and the marine ply is,
although sound, discoloured and stained in place, as well as starting
to cracj a bit. Is it possible to apply something like Teak oil before
marine varnish to help revive the wood?

Teak oil would probably not be a good idea as it can effect the varnish
bond. Scrub it down with an oxalic acid "wood brightener" and rinse well.
After it dries work out any remaining stain with some 120 grit sandpaper.
You might also consider flowing on a coat of epoxy to fill the checking and
seal everything before topping with a UV resistant varnish.

linseed (flaxseed) is the oil in oil-based paints and varnishes. it is
often used by itslef (boiled linseed oil) diluted 50% with kerosene or
paint thinner so it will soak into the wood grain. It costs less than
paint or varnish. I use it that way alone on the inside or as a
primer-sealer on the outside before painting or varnishing.

You've just described "teak oil" (diluted linseed oil).

Personally I like Owatrol for a base coat on weathered wood before
revarnishing. Use neat till it will take no more, then 1:1 with any
alkyd and *most* one pot varnishes then halve the ratio again in the
next few coats. Its a flow improver so you want to keep using 10% - 20%
right through. It also does wonders with rust! Google for it.

The traditional way with preparing brightwork for revarnish is to
scrape. There's a variety of useful scrapers out there usually with a
2 inch or 3 inch blade which can be turned or replaced. They usually
have a yellow handle, I notice (!)
The idea of a wood floor buffer comes to mind as well.....
