Hynautic Steering

[Targojoe]

Can anyone tell me what model number or serial number would have been used in my 78 F-36? I need to replace the seal in the upper helm..
Thanks for your help

Should be a H-20 series most likely a H-25 or 26 ( same kits ) . There are a early and a late kit using 2 different shaft seals . You can ID the seals but easy to mistake the 2 until the helm is pulled apart . I would have both kits ready just in case .

The Hynautic kit numbers are HS-01 (External Black Seal ) or HS-02 (Internal Seal w/White Visible Wiper )

Thanks prowlerfish! It's an H25s and it's the HS-02 seal kit...(interior seal)

Now the hynautic reservoir has instructions on it that says I can use transmission fluid...should I or should I not? I did put about a quart of tranny fluid in it two years ago...

Should I flush it all out and put hynautic fluid in it or is tyranny fluid ok?

[prowlersfish]

I would use Hynautic fluid the manual says us ATF for Emergencies

Is seastar brand ok to use?

[prowlersfish]

Same company . Yes

Well I solved the leaky helm. I rebuilt that and everything is good but now my steering ram is leaking! There are no numbers on it so would anyone happen to know which model I need for an F 36? I'm seeing all different kinds K 10 K 13 K 14 K 19 which one do I need?

[prowlersfish]

Pretty sure its a k-18 or k19 , same kit KS-02 k18 has 7" travel and K19 has 9" I believe I have the info on the boat . Will check tomorrow .

[prowlersfish]

It is the K19

[Targojoe]

Thanks again! Yes it is...I measured the travel based on what you said in the previous post...
I ordered kit ks-02 and I'm just waiting for its arrival
