Ford Lehman 120hp conversion to NMEA sender units

Hi all have the Ford Lehman 120 and have 4 x Raymarine E140w installed and would love to use the gauges and other monitoring equipment in the E140w arsenal, is it possible to install nmea compatible sender units in place of the old analog units ? Does seem the easiest way around this problem rather than installing conversion box Analog to NMEA ?
Would ideally like engine Temp , revs , oil pressure , water pump pressure may be even EGT and I see the e120w has a flow meter reader that would be handy as the Lehman 120 returns bigger all to the tank.
Thanks in advance guys.
Michael 😀

A conversion box is not hard to install. You can piggyback off the existing senders, keep the old displays in place and get the data into your Raymarine unit. I've used Alba Combi to do so with Simrad and it works well. It's your call whether that is preferred over replacing all the old senders on the engines with new N2K senders.

Donít complicate the simple.

If your existing senders are working fine, use them in conjunction with a N2k interface to send the engine data to your Raymarine gear. We went with Chetco Digital, but there are others (Actisense, Noland, etc) that will do a great job.

How have you found the Chetco?

We were interested in that solution as well...

Excellent product and support. The owner (who designed the unit and knows all its specs) answers the phone and is patient with all tech questions. If a change is needed, they will send a file to upload into the unit.

As far as the data, everything is seamlessly integrated into the Raymarine network.
