I think it's a much higher grade than the stuff used in trim tilt systems, I wouldn't use anything less than what the manufacturers suggest. I think you'll find it's an Aircraft speced grade.

Can you use the Teleflex fluid in the Trim Tilt on the engine without any problems then?

I wouldn't have a clue, all I would suggest is to follow manufacturers recomendations, particularly if you have warranties etc. I guess for emergancy applications where nothing else is available then you'd have to use other types of oils, but you'd have to perge them from your system as soon as you could.

Personally I'd use exactly what it asks for.There's liable to be additives to cope specifically with marine use in it-in the same way that it's a bad idea to use normal EP90 in a lower unit.

The Teleflex fluid, as I recall, is an aviation grade hydraulic fluid. The manual states that in situations where it is not available, Automatic Transmission Fluid can be used, with a heavier feel in the steering due to the higher viscosity. Others have told me (haven't made any attempt to confirm this) that in an emergency, just about any liquid can be used, at the expense of seals (if using high hydrocarbon fluids) and metal parts (if using acidic fluids.)

I don't remember what the tilt/trim specs call for, so can't help you there.

Chris, I had an old V6 Mariner a while back. Had a Merc dealer service the engine and replace a leaking seal on the trim. Fortnight later it was leaking again. Answer to the problem, drain the hydraulic fluid out and replace with EP90. Took the trim motor a litle longer to tim up and down but stopped leaking and never had another problem with it. Would I mix hydraulic fluids, yes these are low pressure quite crude systems. Afterall what do you put in the car steering, the same stuff as the manufacturer or a bottle of stuff from Halfords.

Pete

But we always try to stick with manufacturers recommended grades though, be it Shell, BP, Mobile or Halfords....Don't we?
