* Older Hynautic System (1983). Does one have to use the Hynautic fluid or are there other acceptable substitutes? Thanks
*MY old boat had it when I bought it....converted to regular hydraulic fluid/seastar steering fluidJay N wrote:
Rick, didn't some of the older Hynautic systems use antifreeze?
*On my last boat I just used Sea Star steering fluid...that's what the PO used on my new to me 1988 trawler.* Almost any fluid would work for this type of application...just the seals I would worry about.Fighterpilot wrote:

You can always use a UV tracer dye in the clear stuff. Even with red fluid, it takes a pretty good leak to be visible unless it drips on something light or puddles.Fighterpilot wrote:
Looking for something red, since I am having a hard time finding a leak. Present fluid is clear.
*Hynautic used/uses antifreeze in their hydraulic engine control systems (throttle and gear) - their power steering systems uses hydraulic oil.Jay N wrote:

I know this is an old thread, but I was searching for hydralic fluid for my old Hynautic steering system, this thread came up. Thanks for the lead to Aircraft Spruce as I just ordered 6 qts of phillips 66 X/C.
