Can anyone recommend a fuel flow meter that plugs directly into the ECM instead of installing a valve in the gas lines?
It can be a multi-purpose gauge, too.

Are these SmartCraft ready engines? If yes, many/most Northstar/Navman GPS units are SmartCraft compatible and you need to add a gateway between the engine and the GPS unit.
However, adding an in-line flow meter is no big deal. Is there a reason you want to avoid that?

There was a device that would connect to MEFI 2 and 3 EFI modules and provide fuel flow figures. I think B&G made it. It has been discontinued. On the other hand, fuel flow numbers are pretty predictable based on load, RPM, and conditions. Every time I check my burn rates with the Rinda EFI tester, they are the same as before. Borrow or buy a Rinda tester and spend some time doing trials.

I agree with Frank (who woudn't). When I installed them on my gas powered boat, once I found the sweet spot, I never looked at them again, except to impress the fuel dock guy with predicting how much gas my tank would hold. So if you could figure out your sweet spot without installing anything, that would be the best.

To answer estebanj first, The engines are not Smartcraft engines. This is a 1997 boat with twin 7.4MPI's.
Anf FRank, you mention the cercumstances where I want to know what my burn rate is. I have a variety of loads from just me and the wife as well as others where there is a boat load of friends out for the day. Each is differnt and the fuel flow meters will allow be to run at the most economical speeds. That's exactly why I want the gauge/meter.
And regarding my choice not to installa valve, if the engine systems already can give me the information electronically by tapping tinot the ECM, then why would I want to cut into the fuel lines of both engines to install a valve? It makes no sense.
But still, for all of you, thanks for taking the time to respond to my inquiry.
Happy boating!

Well, my wife for one -- just on principle.
What briman said is correct. The biggest determinate on your 370 is going to be fuel. So beg, borrow or um.. whatever a Rinda test and run her with no fuel and full fuel. The rest you can extrapolate mathematically. I've done it and it's pretty accurate. My 330DA is a lot more load sensitive than your 370 is. I plug my Rinda tester in every now and then and the I can predict the results before they are displayed on the LCD.
BTW, As they say...
"Hey you in Joisey? I'm in Joisey, too! What exit?"
Maybe you can try my Rinda for a couple of days.
Best regards,
Frank
