CapEric, Here are the basics for the HC5369:

Cylinder Body - brass
Stroke = 9 inches
Bore = 1.5 inches
Fluid Volume = 13.1 = Cubic inches
Shaft diameter = 5/8 inch
Total length = 29 inches
Span from retracted shaft end to mounting foot = 23.25 inches

My Hynautics cylinder was different by the following:
Shaft diameter = 3/4 inches
Total length = 26.5 inches
Span from retracted shaft to mount = (about four inches less) I didn't write that in my notes.
Stroke = estimated between 9 & 10 inches
Fluid Volume = estimated at 13.2 cubic inches (this slightly smaller volume in the new cylinder will lower the 5.4 turns of my wheel from lock to lock by a small amount)

You will find Gary McMath at Seastar Soutions very helpful with specific questions about the HC5369 or other options. Gary.McMath@seastarsolutions

Re: Hynautics Steering

Cap Erict3, I need to correct the data in my last post where I stated that the span from the retracted shafts end to the mounting foot is 24.25 inches. This is the distance written in the Sea Stars Solutions manual, but direct observation reveals this distance as 19.25 inches. It's difficult for me to accept that the manual is wrong. I've sent an inquiry to Sea Stars Solutions and I will share the results.

I'm only posting this as I said that I would share the response regarding my question about the questionable data in the manual. I only received the advice from SeaStar Solutions to adapt my installation to the characteristics of my boat. Essentially, my question about the incorrect data in the installation/owner's manual was ignored. I'll add that, except for this apparent misinformation in the manual, the technical support from SeaStar Solutions has been excellent.

Re: Hynautics Steering

Happy Day! I finished my hydraulics refit. Flushed the old RO hydraulic oil and filled with new fluid. Bled out all the air. My new system is pressurized and all is functioning well.

Re: Hynautics Steering

Glad to hear that it worked out. I hope that you get decades of service from the upgrade.
