Ok... full story...
Replaced the trim pump reservoir about 4 years ago. New reservoir cost me $180!!!
Trim pump's leaking again, just slowly. So I pull the pump, thinking it's just the reservoir 'O' ring. Get a new 'O' ring and fit it up (previous 'O' ring, supplied with the new reservoir, WAS the wrong size :facepalm
. Tip the pump over at 45? and voila... it's leaking :facepalm: but not the new 'O' ring, the 'seam' between the top and bottom parts of the reservoir. Bugger! There's no way I'm paying $180 again... So I notice a Parker Hydraulics logo and a part number on the reservoir. I find out that this Mercruiser trim pump is just a badged up Parker 108 series pump... Fantastic! Called the local Parker agents in Australia. Yep, they got them, only $59... Yes please, I'll have one... 
So... The question... The pump contained 'Mercruiser Trim and Power Steering Fluid'. Looks just like a light weight oil to me, but.... Reading up Merc say to use their fluid (no really surprise there, ah), or in a pinch use 10W30 or 10W40... So, what ACTUALLY is Merc's Trim and steering fluid? Is it one of those oils?
One more question ('cause I'm real dumb). I have a bottle ('bout 1.5 litres) of Shell Helix 10W50 Full Synthetic. Can I just use that, or do I need to clean ALL of the oil out of the hoses and rams too? ie, can I mix the original ??? with this fully synthetic?
Thanks for your patience guys.... And sorry for 'another oil thread' (but I think this one is a little different, I hope)...
