Hydraulic steering outboard twin yam 200

[frankmac3]

Hi All, we just came back from our summer trip to Maiorca, we did the 125 milles each passage  with our cap camarat 8.5 without problems, the boat performs well, we did as well 200 milles all around the island, it was great. I would like just to point out a small failure that we had with our hydraulic steering, one of the hydraulic steering tube was damaged and I lost some oil, fortunately it happened to me close to my marina in Maiorca. i called the technical service to replace the tube and i complaint to my Jeanneau dealer since my boat and engines are from 2016 and the hull is from 2014. They told me that this is someting that could happend but not ussually, so my recomendation to all owners of outboard boats is that please check the tubes of the steering very carefully at least once per season, my technical service and my self did not a good job......thanks for your time

Hi Frank, this is actually an issue that has happened to a number of us owners (twin and single). Check out the ‘hydraulic steering failure’ post link.  This failure can be caused by several factors; the hose is crimping when you raise or turn the engines, or the hose could be rubbing against something and wearing a friction hole, which was my issue. 

As you mentioned, the best way to avoid a potential serious issue is to regularly check not only the hoses, connection, and steering cylinder for leaks, but have someone lift and lower, and turn the engines from side to side and inspect to make sure they are clear from crimping and friction.

I have a question for twin engine 895 owners.  (if i should start a new thread, let me know, i don't want OP to not get his (hers) issue addressed).

The steering wheel takes 7 turns to go from full starboard to full port.  ( i think too many)

Both engines are attached to the hydraulic helm with cylinders on each engine (lots of hoses back in the splash well). there is also a tie bar that connects both engines.  The owners manual has only one engine with the hydraulic cylinder and the other only steered by the tie bar.  

I am thinking, that since twice the fluid is necessary to activate two cylinders,  that is why it requires so many turns to go from port to starboard. 


It doesn't add safety to have to separate cylinders since a line leak will deactivate the entire system.  i guess if a cylinder went bad it other one would still operate.


 If two is appropriate i am thinking they should have put in a larger helm pump.  

What do your boats have and how many turns does your helm require?

Bluedart,

7 turns full starboard to full port is a lot. My 895 with a single 300 takes 4 turns. I tested an 895 with twins. I don’t know what the steering setup was but I did notice it took a lot of effort to turn the wheel. 1000 pounds and twin props is a lot to turn with a manual steering pump. Perhaps that’s why that have yours set up in his manner as more turns would result in less steering effort.

I am a twin 895 owner and the steering is the same - 7+ turns side to side.

Dealer reported that this not correct.  said it should be 3.5 turns.  

Do you have steering cylinders on each motor or just on the starboard one?

I think Capt Lynn has a custom rig as I understand the 300 was a dealer install.  I have 2x200s and it takes 7.5 full rotations of the wheel.  Is there anyone with twins who only has 4 ish turns stop to stop?

[bluedart]

i did some research on sea star site.

It seems like Jeanneau could have installed a single cylinder set up or a duel set up.  the Duel does take 7+ turns.  the single is 5 or so.

I would have preferred less turns in the steering. A friend of my with the same engines on a grady white has the single set up and it seems fine.  Its a pretty heavy boat also.   He has it a few years. 

If i really dislike it i guess i can remove one cylinder.  The single and duel systems use the same cylinder and tie bar.  

Right now my bow thruster is not working correctly so i will focus on that first.  The battery doesn't seem to be charging.



OUTBOARD INSTALLATION RECOMMENDATIONS



Outboard recommendations made in this section are based on our experience with typical installations, applications and usage. Ensure you select the system which provides the best comfort versus performance. It is the boat manufacturer and the installer’s responsibility to ensure the components selected are sufficiently validated on the boat for safe and acceptable operation. DO NOT use SeaStar Solutions Steering in applications they are not intended for.

Hi Bluedart, regarding your thruster battery, this is a known issue for some 895 owners.  You can find more information about it under the “NC 895” thread and look for Capt’n Lynn’s post on April 30 at 7:20pm. 

Good luck.

Ron

Thanks Cap't n Ron.  i will look and keep the forum posted.
