Have to have it
Not much to say, but we have to use this when servicing a seastar system. Its pricey, but no other real option. The bottle came properly packaged and and sealed. I will purchase this again if I need more. Its much easier to have this delivered to your house than to go to the store and pay more. The fluid works as intended. Its quality stuff made specifically for the SeaStar steering system.

Worked great!
I used this product to flush and fill the steering system on my classic Grady-White Explorer 24. It worked just fine, though I used a good deal more than one quart.

Stick with brand for dependability
Bought it because my seastar hydraulic on the Northeiver gave out. Didn't want to use another brand as I dont want to be left stranded. So far so good.
