General Discussion / Re: Mercury V6 Tilt and Trim fluid

« Last post by UKMike on February 10, 2019, 05:00:06 AM »

Just looking at yours, is that an eaton motor on the pump? A square or round one? looks the same as mine from what I can see, how old is the unit on yours?

I managed to buy a few OEM seal kits including check valve kits 41482A 2 for the main ram. Did a full rebuild on one unit and part rebuild on the second unit and I can tell you I searched everywhere for these parts, they are few and far between now so if you do rebuild let me know as I might have some spare new OEM kits.

What fluid do you have in yours? Might be worth thinking about the ATF-Dex 2. I'll dig out the links to the sites where I got the info from if it helps?

Just a thought but if the seals you have work a touch and you're getting leak down, you wont hurt anything if you drain what you currently have in the unit and replace with Dex 2 as it may well give you a few more seasons before needing to rebuild.

Over here the price of the Quicksilver tilt and trim fluid is about $30 per 1L yet the dex 2 is $25 per 5L

Let me know if you want the links info anytime or if you do rebuild and you need any kits.

Best
Mike.

Glad it worked !
My trim holds but the tilt will leak down after about one half hour.
Needs a rebuild ...

Thanks Gregg,

I already replaced that, bought all new OEM seals and relief valve, full kit but didn't remove the issue with the leak down on pressure, BUT great news, I did some research based on your last post with the older info and it seems the old Tilt & Trim units like mine actually do work much more efficiently with ATF-A or equivalent, and the seals throughout need the older mineral based lubes to really be top performance. I've spent over 20hrs reading about the older tilt and trim units and luckily I got some info from a site in the states that advised backward compatible fluids. It said something like the old ATF-A fluids were made from Whale oil and "what's now classed as other endangered species" so it was stopped being used BUT they found another mineral replacement. The say the closest to it is ATF Dexron 2 as this is mineral, and they advised against Dexron 3 as that is synthetic, and they say the older units and the seals still out there for the older units, need the mineral based oils or they don't work well and the seals melt in no time.

I've drained the unit and replaced with ATF Dex 2 and it's totally different, the pressure is much higher and the ram is solid, and has been extended for 29 hours now with no pressure drop. It's not currently under full resistance so may compress in those conditions but the new fluid seems to have done the job. I'll definitely put this in the other second unit I have as a spare.

Thanks again to all the great folks for all your support, great support community on here>>>

Best
Mike.
