I purchased a model 2110 Nautic star from factory 7 years ago. The steering wheel sticks and slips when on the water at all speeds. The grease is ample,

Any suggestions and or comments are greatly appreciated as dead sticking is close .

Cable or hydraulic steering?

Good question , I'll find out and post , thank you sir !

Hydraulic system. Appears easy to fill and purge just need fitting sizes . I'll take any suggestions as where to purchase.

years ago I found a fill/bleeder kit online....somewhere. Tubing yoke with quick connect fittings on each end and bleeder valve in the middle for the cylinder on the engine. Also a hose to attach to bottle to keep supply of fluid constant while turning wheel back and forth purging air and filling system...

Can find them on eBay for about $15

Done, thanks !!

I bought one of these kits online for about $13 total. I have about a half of a bottle of Sea Star hydraulic fluid. If I already have fluid in the system, can I get by with just using this bottle instead of hooking up a full bottle? That dang Sea Star fluid is expensive!

Some folks use power steering fluid and have moderate success.

yes, you will be fine.

I use a kerr qt. jar and tube into about 1/2" of fluid and bleed like old style brakes, I save any that comes out and re-use it.

The fittings on the steering cylinder should have bleeders made into them.

There are connections underneath , yes. IDK if they are bleeders. I watched you tube and bled out the hydraulic fluid via their methodologies. Thx

After bleeding the two steering ports twice . Took said boat with hydraulic steering issue to Graham. Works like an almost new device. Thanks to one and all for your ideas and support . T-top has been fixed as well , no more shake rattle and pop. Anchors placed thru deck on 8 of the 16 screw holes. Fish don't know the hurting I'm about to put on them !
