So I'm thinking that I'd like to add a Fuel flo metering system to the boat. Thinking it will give me piece of mind on those long over-night trips out to the canyons and back.

I'm curious to hear from those that have a system installed. Any issues? Glad you have it? Sorry you did it?
Tia,
 
Had it on my old boat. Was probably the best thing I ever installed on the boat.
 
I have 2 sets, one B&Gthat provides GPH & resettable G/U plus other engine data directly from the ECM on my gassers (via algorithmic calculations) without the need for a flow sensor, and also a set of GPH-interfaced Floscan 9000's & flow sensors that also supply dynamic NMPG. I really like both as valuable assets on the dash. Both kinds can and need to be calibrated for great accuracy. The F/S 9000's are terrific tach replacements , providing very easily readable LCD : RPMs, Eng. Hrs, GPH, NMPG, and resettable G/U.

But I wouldn't be without the working conventional gas gauges as well as a true reality check in case the totalizers do not get zeroed out at fill or the fill was not fully topped up for some reason.

I also always enter into the logbook the totalizer readings at fill, actual gallons pumped per side and whether the totalizers and distance log were zeroed out.

For me they are definitely worth the cost.
 
Had a gas floscan on my twin 454's before the refit.

DEADLY ACCURATE to 3 -5 gallons on a 200plus gallon fillup.

If they were not cost prohibitive on my diesels I would do it again.

Installed Foscan/twinscan on my carbed 454 Crusaders. Very accurate, get real time fuel flow on both engines plus total gallons used since re-set. Installed the system myself, so not very hard to do. Was somewhat nervous about cutting into fuel lines for sensors, but no problem.
 
I have the Floscan Twinscans also. Love them. Helps diagnose problems before you know you have them.
 
I have a Flo Scan and love it. The only thing I have noticed is that at idle speed in my 5.7L the fuel flow is too low to be measured. If we spend a lot of time idling around, the gauge is low by about 5 percent. When cruising all day the Flo Scan is within 1 percent of actual. A much better devise than a typical crummy fuel level indicator.
 
Had them on my old boat, best item I ever purchased. Had Floscan. Worth every penny,then some.

We've had a Flo Scan on the dishing boat for a number of years and it is fantastic. I got the flo meters for my Garmin this past summer and love them.
 
Great customer support too, when I had installation quesions. My Twinscan was under the tree two years ago today. great present from my wife.
 
I have Flo Scans on my boat. twin big blocks. I love them. I truly believe that they paid for themselves within the first year. It's amazing how when you can see how much fuel you are burning at any given time, you tend to back out of the throttle to find the best economy. My first mate has learned what the numbers mean now, when she sees me approaching 30GPH she tends to inform me that it's time to slow down.

Maretron just came out with a great diesel set up. You need a NMEA2000 network for it though.
The gas engine digital version of flow scans have been on the market for some time and aren't that expensive.

I'm guessing you have diesels so I'm not sure this will help, FW Murphy makes some that plug into the CANBUS of newer Crusaders - gives you more info then you'd ever need to know...
 
Speaking for myself, I would rather spend the money on gas rather than the gas meters which were not cheap.

==============================================

The MSRP on these is $400 each.

Twin diesel installations require four senders so we're already at $1,600.00
plus the monitor itself
plus cables, & etc . . .

If you use the boat, they will pay for themselves in a year or two despite the install cost. Even if you just save a gallon or two per side an hour...

They are also handy to let you know that something isn't right, from dirty props or worst.
 
does any one have Lowrance flow sensors ? I've put together the backbone of NEMA 2K system with 2 hds units, but haven't found anyone using their sensors...

The only thing I did different from Gregory was that I had new fuel lines made up with ends installed by a hydraulic shop so everything plumbed right in.
 
Yes I have Lowrance. They work great and were about 1/2 the cost of the FloScan. I highly recommend them (Lowrance). Also, very easy to install. Cutting the rubber fuel lines was like cutting butter. The Lowrance sensors have nice fittings that fit into your rubber fuel lines. Just make sure you mount them vertical.
