    I have a 2013 Yamaha F70 and I have installed a Baystar steering system. I noticed that when I connected the cylinder piston and support rods on my motor the turn to lock has gotten smaller (meaning I can not turn the engine as far as it could go without the cylinder connected) Loss of travel is about 10* in both directions. I have not connected any hydraulic yet so that is not the issue.

    On another note..
    Rodent/s got in my motor this winter and chewed some wires. Part was towards the front on the lower part of engine very close to center.
    I can not locate this part in Yamahas schematic. Does anyone happen to know what is, what it does and where can I get one ?
    Thank you for any help 20210308_214827.jpg 20210308_214827.jpg

    Some of those connectors are repairable with the correct tool. What was it connected to? There must be some broken wires laying somewhere. Wire harnesses often have extra wiring and connectors for optional equipment, so it may not be a problem.

    As far as the turning degrees, that appears to be a mechanical issue, so you should be able to see what is stopping it. Which side is it turning less?

    Gonzo,
    The wires- the critters had a field day on that wire, its in 3 pieces. All the wires are taped together so I don't know where it goes yet, just noticed last night
    Thanks for the link

    As for the steering it is about identical as to not turning all the way in both directions. I am free hand moving the motor, no hydraulics involved and what it seems to me is the support rods are bottoming out inside the piston. I'm thinking I either need another groove in the rod or the length needs to be about 1/2"shorter.

    I'll be contacting Baystar today and hopefully you guys or them can help.

    Seastar technical support is exceptional. They always call back, so don't not leave a message. It it corporate's way of managing their call center.

    I, too, might be inclined to attempt repairing that connector. You'll need a special tool to dewire it and probably another tool to put connections back on.

    Here are some diagrams where you can id the damaged item.

    Thanks Fallguy for the info
    I looked for the part already and I don't seem to see it there. It's basically an end of the line fitting with a connector for something in the future.
    I'll check Gonzos link tonight for the part.

    Talked with Dometic/Baystar today and they/Gary said I have the right parts (he didnt know what would stop it so he asked for pictures to try and figure this out.)
    I'll be in touch when it gets resolved.
    Thanks again guys

    I think it looks like a Commandlink fitting, but just a guess.

    Well I got an answer from Dometic. Not really what I wanted to hear but its best designed by them
    FYI-- Yamaha F70 has a travel of 40* each direction so 80* Port to Starboard

    Here's Dometics reply
    Hey Frank

    All hydraulic steering cylinders are designed to bottom out before the engine hits it stops.

    They also are design to give 60 degrees of articulation.

    The reason for bottoming out before the engine stops is so that there is no lateral pressure from the steering rod onto the glands.

    This prevents premature end gland failure.

    From the picture you sent the cylinder is getting it full stroke.

    I guess I had it installed correct just seemed like it wasn't traveling enough, I still wish it was more

    Fallguy looks like you are correct. Thank you for the find
