Hynautic Control Leaking

[scottinsydney]

My wheelhouse port throttle control has started leaking out the shaft that connects to the control arm. (Six years ago a similar thing happened to another control and was fixed by the seller.)

There is still supply of the seal kit but the very brief response from the seller was


"The ECS-06 seal kits are in stock and are for the shift & throttle slave units."

My question is: What does the seller mean by slave units? There are four controls on my boat and they all look exactly the same.

Page 21 Figure 21 of the Hynautic PDF...ECS-05 seal kit. To your question, slaves cylinders are the hydraulic blocks on your engines and transmissions. They have different rebuild kit (ECS-06). We did a 100% rebuild of every o-ring, seal, schrader valve and reservoir in our hynautic controls (3 stations)...manual is helpful. There are shorter versions of the manual online but the link I sent it most helpful. Had the best luck on parts with Seamar (second link above) - seems they supply lots of these high reliability systems to the Alaskan fishing fleet and had good inventory when nobody else did during covid. Good luck.

Won't help you in the Land of Oz, but I used a bunch of this stuff to flush and fill system. The specified Hynautic HA5455 fluid was a combo of unavailable and extremely expensive. Checked the SDS before substituting and this was as close as possible:

Sorry to blow up the thread...I just wish all this information had been in one place when I prepped my rebuild so doing info-share!

Thank you.

ECS-05 is now obsolete, but we have found a seal supplier here who can match parts. I do not want to replace the hydraulic controls for electric versions. They Hynautics work just fine.
