Default Simrad AP-11 installation

I just purchased an AP-11 for my new boat. I have been reading the manuals that came with it and searched the archives here but still have some unanswered questions.

1. The rudder feedback interface (LFI3000MK2) needs to be connected to the linear feedback unit. It's not clear how to open the interface box to complete the wiring.

I just looked a bit harder at this and found the rubber plugs that hide the screws, so that one's answered

2. There are no clear instructions as to how to connect the drive unit (RPU80) to the steering system. I presume that I tee into the hoses from the helm pump. The instruction show two examples of connecting a manual system and a Capistrano system but neither seem appropriate in my case (Seastar hydraulic steering on twin OBs).

The junction box J3000, terminates all of the interface wires; compass , pump, rudder sensor, 12V (+&-) and Main Control. Also, all of the shields from the various units terminate at the J-box (no shield on the pump wires). There is a post adjacent to each terminating screw. Wrap the shield around the post. There is also a metal strip that screws into the j-box base plate and runs the entire length of the terminal strip. Unscrew this plate and when all of the wires have been terminated, place the ends of the shields from all of the cables under this strip and screw it back to the base plate.

I cannot recall the exact hydraulic hookup of my system which is also teleflex. From memory, you must tee-off from the teleflex pump the two hoses that go to the steering piston. The tee'd hoses go to the 2 outside ports of the rpu 80. Don't worry about which goes where, the ap11 tests the system and determines which is which during alignment. That is also true when you connect the u-80 wires to the jbox. Makes no difference which goes where. The center port of the u-80 hydraulic pump goes to an available center port of the telefelx pump which obviously is plugged. The u-80 comes with an assortment of brass hydraulic fittings. Be sure to use the fittings that also use an O-ring seal to the u-80 hydraulic pump.
What type of rudder feedback unit do you have?? The AP11 has a choice of 3.

Thanks Gil,

I have the J300X junction box, but I believe the hookup is very similar. I did find a diagram of the hydraulic hookup at www.seastarsteering.com . Did you buy the "fitting kit" or did you buy the hydraulic hose and fittings separately?

I have the linear feedback unit (LF3000). I know the RF3000 is for inboards, what's the other feedback unit?

edk;
You should have received 2 sets of 3 hydraulic fittings with the u-80. One set is metric and the other SAE. The one set screws into the u-80 hydraulic pump and provides SAE male output. That is where you use the O-rings to seal the seat to the pump housing. Check with your Simrad dealer if you didn't get the fittings. I bought my AP11 @ Langer-Krell in Miami and it included the fittings.
The LF3000 rudder sensor unit should work fine for your steering. I have a teleflex 5340 (I think) and teleflex makes a rudder sensor specifically designed for this cylinder and works with the AP11. It is magnetically coupled and supposedly lasts longer since there are no moving parts. Simrad will supply the AP11 with this unit, but unless you have the 5340, it will not work mechanically.

There was a post a couple of weeks ago by POP I, I believe, who was also undertaking an AP11 installation. I had made a few suggestions for him regarding installation but never heard back. You may want to search back on THT and find the thread. There were a few suggestions that you may want to look at. Good luck, I am off to the the Keys for the weekend, be back Monday.

Thanks again,

I found that other post and it was quite helpful.

I did get those fittings with the pump. I guess you were replacing an older pilot so you did not need to replumb the steering pump. Those are the pieces I am missing. I will probably get a local hydraulic supply place to make up hoses for me. I did that when I replaced the steering on my old boat.

Do yourself a favor and get shut-off valves when you have the t-eed lines made up. It is a cheap investment, but more then pays for itself if you ever have to isolate/remove them pumpset.

Ed, just curious, why the J300 instead of the J3000, if I remember correctly the J300 is only necessary with the RPU160 (larger) pump, do you have dual cylinders?
BTW, the hook up IS the same, in fact they look almost identical.

The reason I got the J300X is that it has a radar output. I am also installing a NAVnet radar which, with the appropriate heading input, can overlay radar and plotter. Furno sell a heading sensor that does the same thing, but it's > $700 retail. The J300X supplies the same data at less cost. Some people told me that the rate compass was also a requirement to enable the overlay but that does not seem to be the case. I got it anyway as everyone I spoke to said it was a big improvement over the standard fluxgate compass.

Thanks neighbor, nothing like the rest of the story, sounds like a great suite of goodies you got going there. Wait til you get to the autotune part, very cool. What kind of boat? I live just West of you and keep mine on Biscayne Bay in Miami.

Actually, edk it's a good thing you got the rate sensor compass because you do need it and the J300X to get the right signal for the NavNet radar. I went through this with Furuno tech support on the phone last year -- I assume they were right (always some doubt). But you won't regret the upgrade. As I noted before, after yu do the compass calibration, be sure to correct the heading so it reads exactly the same as your GPS. That gives you the best steering to a waypoint with no wandering.

It's a 25 Contender. I should be taking delivery of it next week.

You are probably right. I got mixed opinions on whether the rate sensor was necessary, but I heard enough good things about it that I decided to get it anyway. Thanks for the advice.

edK,
Upgrading electronics on my Grady as well, just wondering where you decided to purchase from. AP-11 does look like a fine instrument.

Consumer Marine. (www.consumermarine.com) It is my first experience dealing with them - no complaints so far. I also purchased a Furuno NAVnet plotter (GP1700C) from them. When I powered it up I noticed that it had a bad pixel. I called them today and they said to send it back and they would send a replacement as soon as they received it. Their prices are good - they had some boat show specials which were even better. Everything shipped the day I ordered it - and I didn't place the order until 4 p.m.

Just noticed that 'Santa' is almost ready for delivery of your 25. I have a 25 with the AP-11 and love them both. Have thought many times about adding a radar and would like to see how you mounted yours.
Happy Holidays!

I am going to be flush mounting a 10" and a 7" Furuno NAVnet displays in a starboard panel recessed into the console. It will be a tight fit - they would not fit in the standard Contender flush mount panel. I am having a custom T-top built with a radar mount for the radome (It's the 1833C radar). I'll try to get pictures once it's all done.
