Default Steering Help!

Need some help figuring out whats wrong with the steering on my boat. Im a complete idiot when it comes to this kind of thing but thought Id check and see if somebody could tell me some things to check to try to save some $ and keep from going to the mechanic.

There is a lot of play in the steering. The steering wheel turns about 1/3 - 1/4 turn before the motor actually turns. And when the motor does actually turn, its a little jumpy (best way I know to describe it - its almost like its missing).

I took a pic of the setup I have and also a pic of a deteriorated steering cable. Could that be the problem? And how would I go about figuring out what replacement part to buy? Is this something an idiot could fix on his own?

Thanks in advance for any help!

First thing to do is check the fluid level, add fluid if needed and bleed the system

Thnaks for the help!

Sorry to be such an idiot, but 2 questions.

How do I check the fluid?

What type of fluid does it need and where would I buy it?

Check the fluid level in the hydraulic helm, under the steering wheel. Fill with hydraulic fluid as needed , they sell it at West marine and many other places.

You should have a fluid resevoir some where. Looks like an small oil filter but the steering fluid lines go out and in of it. It should have a small crew cap on top. Simply open that and look in. You should see a "full" line and you should top up to that. There may also be a little finger pump on top and a gauge that, once filled, you can pump and it will pressureize the system. Try this before going through the bleeding process as you may not need to.

goos luck.

Menzies,
Seastar systems use the helm as the reservoir, unlike Hynautic.

This is definitely a low fluid/air in the system issue...

Don't need to check it, initially. You've got air in the lines, as evidenced by the notchy steering action. I would take care of the corroded connection first (replace the hose), then completely replace the existing fluid. At that point you'll do the fluid level check.

Checking is easy: Open the fill cap (on top of the helm) and look in. If the cap is horizontal, level should be nearly to the brim. If the cap is somewhat vertical, level should be below the hole just a tad.

Fluid is kind of tricky: Seastar fluid is an aviation grade hydraulic fluid, at about 3x the price. You can get aviation hydraulic fluid (though it's usually color;d) meeting the Mil-5606G spec (which is what Teleflex recommends; I doubt an earlier rev would make any difference at all) through on-line aviation parts places, or possibly your local airport parts supply. If you can't find it, car auto transmission fluid will work.

As an aside, if you're going to do all this, you should probably replace the 2 - ram seals, and the helm seal. Parts are available at West Marine, among others. Takes about 15 minutes (as long as you can get your steering wheel off.)

This location has the procedure starting on Page 15:

Didn't Seastar buy Hynautic and their systems? Did they leave the old name?

Wouldn't a lack of fluid also do that because the pistons on the wheel are dry?

The hydralics are a closed system, so if you have air in there, which i bet you do, you also have a leak somewhere. The filling and bleeding is easy. The hard part comes in identifying the leak. The helms, ports, hoses, conections, seals, ect... are all leak prone in a old sytem. I would advise filling, bleeding, turning the steering wheel aggressively and inspecting for leaks, then the fun begins.

Menzies,
Yes, Hynautic has been owned by Teleflex for quite some time now. But the lines remain separate as far as parts and systems, and they are not interchangable.

Fluid is low, I can see down into the resivoir. Hopefully, refilling will work. Thanks guys!

If you go to the jyasaki direct link to the manual you will see on p.14 that auto transmission fluid Dexon II may be used in an in emergency, and then serviced.
