Raymarine linear drive compatible with Garmin GHC20 auto pilot controller

[GrandWood]

Have a complete autopilot system NIB that came with my 1972 GB36

Raymarine 12v linear drive it’s the type2 short throw
Garmin GHC20 autopilot controllers
Garmin Reactor40 CPU
Garmin GPH-12 ECU

I’ve looked online and they say there compatible with an adaptor cable so that the sea talk works on the NMEA 2000 bus. I would think that the previous owner of the boat would have purchased what was needed. Any info would be much appreciated as a few people have told me there not.

I will give Garmin and Raymarine a call once thanksgiving is over, just thought I could get some info here as well.

Hoping someone would know or have this type of set up. I’m selling the system and want to ensure it’s all good

Garmin makes two versions of the AP, one for hydraulic and one for mechanical. The mechanical version has the clutch output required for the linear drive.

If you have the correct version of the AP there shouldn't be an issue using the Raymarine drive with the Garmin AP. No converter is necessary. A rudder angle indicator should be installed as well.

Thank you sir, much appreciated.

i have before this setup + bg display + simrad display bg windvane+ navico depth speed.
you need nmea 2000 cable network, nmea 2000 power cable. and original cable come gph-12 to any in world 12v linear drive (power reed manual)

also almost every in world linear drive from 12v to 400v commercial ship is analog. on/off/on usually on/of with reverse polarity wire but ecu reverse polarity to linear drive or hydraulic pump .no difference linear drive or hydraulic. linear drive motor power belt in hydraulic motor power pump

Do believe I have NMEA 2000 network that the Garmin chartplotters, vhf is on. It’s located up under the flybridge forward storage area.

Seems all it would need is the rudder position sensor, as the Raymarine drive does not have it internal. Some specific cabling as well looks like.

thanks guys

rudder possition old raymarine work. only need 2 wire cabel.but all this is in box with Garmin autopilot. internal rudder position is bull ****. you need ruder position also included in autopilot kit. i have 1 surplus because I be lazy to remove old raymarine rudder position and install new totally identical like garmin.i think 1 company produce this plastic rudder position for all world company

Selling the goods, keep the following in mind.

As many have mentioned before, Garmin is very proprietary with their equipment. While connecting a Ray to the Garmin might seem to work, to save a few dollars, you never know when it might not work. I wouldn't trust something like that hookup on my boat.

I'd question, who are you going to call for support? Garmin will be limited to their products, Ray, which has been sold several times may not be the best place for support.

Also, Garmin has a way to update charts and Garmin equipment on the network through Active Captain on a chartplotter, can you load Active Captain on a Ray, don't think so.... So you will probably lose any update capabilities for your Garmin autopilot items.

There may also be a problem not only with a rudder indicator, but also with any depth readings. Keep in mind that Garmin uses a setup in the chartplotter where you list the specifics of your boat, ie; draft, beam and air draft so the autopilot can keep you in safe water as it drives.

Selling the goods is usually an As is, Where is, type of deal. You shouldn't offer any guarantees as you don't know what the user will do once the box is opened. IF it worked for you then you can offer how it worked. Pricing will drive the sale, don't look to make much on it.

Good luck.

Any specific questions, PM me.

^^^Charles, thanks for your input, haven’t even had an offer. It’s all new unused equipment, I’ve split it up as well, see how it goes.
