Mercruiser Hyd trim line hookup

[Rranger]

Here are pics of my pump install on a different boat. So I had no idea how it was hooked up before. Pic 1 shows the reverse lock hookup with the black line hooked aft of the clear line. Black line at back clear line nearer the bow of the boat.
Pic 2 shows pump hookup. on stern transom wall off boat with grey line on the left side facing back at it and clear line on the right.
Couple of questions.
I'm trying to prime the system and not having much in results so am wondering if hookup is right.
Should I switch black with grey?
And is clear line on the stern side or bow side of the reverse lockup?
Would like to get this sorted out today so any help would be greatly appreciated..

Thanks Fishermark I'm going to swap the black and grey hose see if that helps. I should have mentioned earlier its a 1988ish 5.7 l and a 888 outdrive. Hopefully someone with the same setup can lend some advice.

Ayuh,..... It sounds like yer trim system is native to the 888,..... MC-1,.....

There's links to the factory manuals up in Don'S Adults Only section at the top of this forum,....

Ok have deduced its hooked up right. However goes up like a champ but doesn't retract. Have bled it numerous times. No pump leaks no hose leaks. Any ideas short of looking in pump??

How easy does it go down with nothing attached? Remove the trim rams and manually lift and lower the outdrive. If it easily drops, then you have at least eliminated corrosion, etc as a possible problem. (There is not nearly as much pressure to the down side as the up side).
