I need to add hydraulic fluid to the steering reservoir on my 190 Outrage. Of course the instructions provided by Ultraflex are as clear as mud. What type of fluid do you use with the Ultraflex system? I'm am told that it is NOT the same as a Seastar system. Any help appreciated, thanks.

Joey,

I just looked at their website and they list an ISO VG 15 oil with 15 cst a at 40 degrees C, viscosity <100, etc, whatever that means. [Suggests searching on] Google [for the term] "ultraflex steering."

I was going to add some synthetic hydraulic fluid to my sea star system, but changed my mind after talking to the company. The can says compatible with all systems. However the company said that I should drain/flush all the other oil out first. If I would completely rebuild my hydraulic system I would go with the synthetic type.
FYIF my lawn service guy, told me that they are now using just regular motor oil or are replacing when servicing hydraulic systems on the zero turn radius mowers. Hard to believe but that is what he said and he has 3 of them.

I've learned after many years of dealing with a wide variety of hydraulic systems that the best course of action is to precisely follow the manufacturers recommendations for adding fluid. Why do anything else?

In marine applications when failure of steering systems can be catastrophic I would be particularly careful.

Having said that, if necessary in order to limp home I would add any oil available to a hydraulic system. Afterward I would drain, flush, and refill with the recommended fluid. This procedure may need to be repeated more than once.

Joey,

I went through the exact same issue with my boat, the product to use is a Mercury product. You are right, the Utraflex product information guide is of no use! I will get the part number off the bottle tonight and post it in a reply. Hope this helps,

Robert

The part is Quicksilver Hydraulic Helm Steering Fluid, part # 92-862014Q 1. I had emailed Chuck Bennette at Whaler about this very topic. The fluid is red in color, not clear, just an FYI.

Thanks for the info Robert that's why this site is what it is..good info. Did you completely flush the system or just add to it?

I justed added it, no need to flush since it is the same fluid as in the system. Talked with the dealer's technician and he told me that this is what he would do if I had brought the boat in for service. Make sure you do not move the steering wheel with the cap off the helm station, this will introduce air into the system. If this happens, you will need to flush and purge the system. Let me know how things go,

Joey -

In doing a google search, the part number you listed is for the helm.

cf: http://greatlakesskipper.com/product/ 20_449_527-steering-mercury-hydraulic-steering/ 6706-mercury-marine-mercury-quicksilver-boat-hydraulic-steering-helm. html

If you check Mercury's site
http://www.mercurymarine.com.au/parts--accessories/oils--lubricants/ gear-lub--lubricants.aspx

The part number appears to be listed as 92 858078Q01

You can also use aircraft mineral oil based hydraulic fluids such as, Phillips X/C MIL-PRF-5606H Hydraulic Fluid. It's one of the types that Teleflex recommends and interchangeable with the Uflex. Mercury helm pumps and cylinders are made by Uflex. To me the red dyed is a plus since it helps to identify leaks. Wag-Aero sent me a flyer this month and that fluid is $5.75 a quart. Sent them an email to verify it now comes in a resealable container.

I need to confirm if the part # did change.I will have to call
Mercury. I did try the great lakes site but it is only showing the steering system. I cannot find the fluid separately. Thanks for help guys.

Joey,

I went to the Boston Whaler dealer and bought mine, Sea Ray of Richmond (Virginia). Also, the local Mercury dealer (Pop's Marine in Williamsburg, VA) has the fluid in stock. If you have difficulty finding the fluid let me know and I can pick some up for you. The "Q" in the item number stands for "quart", it is also available in smaller quantities. Let me know if I can help,

Robert

Did you find the fluid?

Robert,

The part # did in fact change thats what thru me and Big John over at McCarthys off the first time I was looking for it. I went back over and he searched the computer and confirmed the part #. So I did get it.

Secondly, how did you add it and where should the level be?

Thanks.

Joey,

I used a very small funnel and, I think, it is 1/2" from hole for the fill level. You better check your manual on this one, I can't remember the exact language with regard to the fill level. I do remember it clearly stated "do not move the wheel", when you have the fill cap removed.

Thanks Robert. That's the problem I can't find the fill level in the manual. If you find it please let me know.

Joey,

I found it! If your helm station is mounted on an angle, the fluid level should be within 1/2" of the fill hole. If your helm station is mounted horizontal (with boat level), your fluid level should be at the bottom of the fluid fill hole. My boat came with the Uflex steering manual in the owner packet, this is the information source, ableit rather limited. I could not find this information anywhere in the BW owner's manual. Good luck,

Robert V
