1983 Mercury 80hp, System "A" Trim TIlt Question

[DaveHaney1408]

I have a 1983 Mercury 80HP outboard with a System "A" type trim tilt. I just purchased new Trim Tilt Hydraulic lines because the old lines rubber insulation is cracked and falling off. <br /> I want to replace the lines but got stuck on the following:<br /> My manual says "use clean MS,SD,SE,SF 20W, or 5W-30, or 10W-40." <br /> It continuses to say "use one of these fluids to flush the system."<br /> It dont say what fluid I should use to fill the system for use.<br /> Im a technition (Not a boat Tech!) and am use to doing what I read, but it's just so ambiguous!<br /> Are all the fluids listed ok for normal service? <br /> Is one better than the other?<br /> ANd what the heck is MS,SD,SE??<br /> <br /> I'm sitting hear on the 40 Yard line, getting ready to punt! <br /><br />Dave
