Installing a Raymarine i70s & ITC-5 Converter | Instrument Upgrade Guide

Boating with the Baileys

3,097 views

In this video, we install a Raymarine i70s multifunction instrument display along with the ITC-5 converter, upgrading our boat’s instrument system.

This setup allows integration of traditional analogue sensors into a SeaTalkng / NMEA 2000 network, bringing together depth, speed, wind, and more into one display.

In this video we cover:
⚓ Installing the Raymarine i70s display
🔌 Wiring and configuring the ITC-5 converter
📡 Integrating with existing boat sensors
🧭 Connecting into a SeaTalkng / NMEA 2000 network
🛠 Tips for a clean and reliable install

Whether you’re doing a full refit or upgrading older instruments, this is a great way to modernise your boat’s electronics without replacing everything.

Why upgrade?
The i70s gives you a clear, customisable display while the ITC-5 lets you reuse existing transducers — saving money and simplifying installation.

If you’re into:
• Boat electronics upgrades
• DIY sailboat projects
• Marine instrumentation
• Liveaboard improvements

…this video will help you plan your install.

I'm busy ingesting your videos as a learning on pi boat projects. Thank you for them. Though i'm intrigued to hear you talk about the autopilot and wondering why with your experience you are not going the pypilot route ?

Enjoyed your video on integrating the ITC-5 and i70s. Have you finished the follow up you mentioned on adjusting the display modes of the i70s? I’m especially interested in the wind display options

I hope you don’t mind me asking, but do you have a Raymarine GPS antenna installed in your pedestal ?
I have also installed 2 I70s displays with the ITC5 and very impressed with the setup

Hi - Do you know if the ST4000 'Wind Vane' feature still works once the ITC-5 was installed. I 'think' it should as I assume the ST4000 is still connected via it's Seatalk1 connection the a Raymarine E22158 converter (or similar 0183 to N2K 2-way converter). Therefore I'm thinking that the ST4000 should still see wind data translated from the ITC-5 as N2K output, but then it is converted back to Seatalk1 by the E22158 or equivalent, and received on the ST4000's Seatalk1 interface? Whilst not essential, we do use the 'Wind Vane' feature more nowadays to keep us on a fixed angle to the wind. I'm looking at option for electronics upgrades......

Excellent information and clearly presented! I am not a fan of our Raymarine chart plotter or invidual displays. The engineers are clearly not boaters and they do not respond to user feedback. Unfortunately, we are tied into their architecture until we decide to update to B&G.

Apparently the new p70 series is back compatible with old autopilot computers. I have a Raytheon 300 series and I’ve just ordered a p70rs. I’ll let you know if it works. It means the axiom can then run autopilot providing you have installed a seatalk to seatalkng converter
