Hi all the book says EP140 for my rotax 503 gearbox but I have been told EP90 is ok, drained the box last night the old oil looks thick in comparison to the EP90 that I put in, is it important to use EP140.

Generally, the hotter the climate, the higher the oil number.
EP90 should be OK. I have not heard of anyone who has had a failure because of it. Only thing is the oil may get too thin in VERY hot conditions and "weep" out at different places.
Will lubricate just fine though.
