Smartcraft help
 

Twin 525efi's.Using 1 403 screen.
I cannot get it to display both motors.I only get 1.When wired up as a single it shows as the centre motor.
Have checked and double checked settings and connections.
Is there something i have to disconnect.I have also not entered into the screen which motor is port and starboard.
Any help appreciated.

What is a 403? Older smartcraft or vessel view? On the new Simrads/ vessel views there should be a “setup wizard” under the mercury setup tabs that will walk you through engines, fuel tanks etc. Do you have a manual?

It's the latest small screen and I used the setup wizard.Still can only get 1 motor to show.
Connected individually they work fine.

Wonder if your wired correctly
Is there a junction box for each motor?

Yes 2 junction boxes.
There was nothing i saw in the setup to tell the screen which was port and starboard??
I read somewhere that something needed disconnecting on 1 motor?

Motors are identified in the setup
Do you have the CAN P harness (g)?

On my 2 engine set-up I plugged into the 1 J-Box and both engines displayed. Its hard to tell by the photo if the boxes are linked in some way. I did have an older style Raceview that was replaced, probably why mine was plug and play. I bet it has something to do with you running 2 J-boxes, system not able to read both at the same time because both are not "on line" at the same time. . https://cimg7.ibsrv.net/gimg/www.off...1993a01c37.jpg

1 J-Box in lower right corner

Yours is a smartcraft to NEMA install, which you should also have a SC gateway somewhere connecting at (a)

Looks like AllDodge has the answer with the CanP Link Harness. Never tried this but why can't multiple engines just plug into 1 J Box?

When I looked into doing this one of the steps was to have a dealer program the engines for port and starboard. They all come from the factory with the same setting and smartcraft can't connect multiple engines without being properly set first.

Well,
Tried everything
2 J Boxes,1 J Box,1 power source.Still can only get one motor displayed.
In the wizard and hard manual it says nothing about needing dealer involvement.
It even asks how many motors in the wizard.

The above is absolutely correct.
Got our laptop from the race truck,Set the port engine from starboard to port.
All fine now.
