I use trans fluid in my trim pump for my outboard (I use a Mercruiser pump) however the reasoning is because it gives a slight speed advantage over 30 wt. Not speed as in top end, but in operating speed for the up trim, especially when using 24V... 
Other than that I don't see any reason for not using regular ole 30wt as recommended.

i agree with you,but i beleive one could use other fluids,and have no problems.

Huh? I said nothing about Number Six drive oil or transmissions. I only mentioned I use 30 wt oil (any brand) in my trim pumps as suggested by Mercury Racing. I use Type F trans fluid only in Bam transmissions also suggested strongly by Bam. I use Torco MTF oil in dry sump Sixes also strongly suggested by Mercury. I let engineers decide what works best. I hate to experiment at my expense.

I Like to lead and not follow,pushing the limits and trying different things can only push
the limits to better performance.Like I said before mineral is for weed eaters!
It's all good but I've never liked rules and I don't believe engineers are Gods!

Just a thought. Isn't oil, motor or gear, primarily used to lubricate? Though oil is compressable it seems like trans fluid which is made to operate basically as hydraulic fluid with a bunch of cleaner in it, be more efficient?

Talk about engineers, you guys are over engineering a simple hydraulic pump and a couple rams. Put what ever you want in it. The lower viscosity, the faster it will go up and down. Merc used to recommend 20wt.
