I know there are a few conversations addressing the steering set up, but I'd like to hear from y'all on your situation and any remedies you may have tried.
My 2019 NC 895 has 2x Yamaha 200's with 2 sea star hydraulic cylinders connected with a tie rod and a sea star helm pump. The cylinders are 8.34 cu in each and the helm pump is 2.0 cu in per rev, which gives me a forearm burning 8.34 turns lock to lock. I know i chatted with Capt Lynn and his single has 3-4 turns, but what about the rest of you outboard Jeanneau folks?
So, it looks like all the MI boats have shown up with 2 steering cylinders. Each cylinder is 8.34 cuin and the pump pushes 2.0/turn ergo 8.4 turns lock to lock.
Can I get you to look at the helm pump and cylinder on your rig and let me know. Our current game plan is to remove a cylinder from the set up and see how the system works with one cylinder and the existing 2.0 pump.
As for the rest of our 895 community, does anyone have a European build 895 with a single steering cylinder for 2 200s?
I'm not happy with the steering as well (2xF200). Stumbled upon this doc and from page 12 it looks like dual-cylinder setup without power assist is expected to have ~8 turns. Upgrade to 2.4cu and add Power Assist should improve the situation. I'm currently clarifying and estimating what would it cost me to go through it.
The 2.4 pump will take you from 8.3 turns down to 6.9 turns. I think we're going to remove a cylinder and try it out, and if its too heavy at the helm, then we'll either return it to the original configuration or add a power steering pump.
I was scheduling an appointment to my service center and explained to them the issue and a possible remedy. And I was told that SeaStar Alignment Valve supposed to solve this issue in dual cylinder setups. Checked the docs and it looks reasonable. Also, PA setups need this unit too. Willing to try
So I went through this process with the valve and power assist.
The valve was a wrong idea. Single PA can't move it and another PA pump is required to work with the second cylinder. Scratch that idea. Thanks to Amazon for refund convenience
The power assist pump is installed and running as expected: smooth like butter. Totally different story. Definitely recommend. Even tho it didn't reduce amount of turns lock-to-lock, it made it less annoying and more predictable.
But I still want to get to 4 turns setup. The next step is to replace helm pump with 2.4cu. I'll keep you posted.
I think the system will work on a single cylinder. I've seen boats with slightly smaller twin OB motors with a single steering cylinder. The force at the helm would go up, but the question is how significant would the increase be, and with the pump assist, would it even be noticeable.
