Anyone have any experience with the thing? How's the reliability and accuracy?
My Yamaha gauge is shot and at cost the thing is over three bills. At $149 for the Navman it's worth looking at. I have heard some not so good things about Navman sonar/fishfinders, etc. and am hoping this product does not fall into that quality class.
All reports I've read are positive on the Navman Fuel guage. However, it is the same as the Standard FF-41 which normally sells for more. There is a rebate on the Standard of $75 thru the end of March....which makes it the cheaper choice.
Lots of posts on where to buy it on this board and elsewhere
If you follow the instructions in the manual that comes with the unit, as I did, the accuracy can be as good as 2/10 of a gallon of what you actually have in the tank.
Does this navman model work on fuel injected outboards? I have a Yamaha 200 OX66 and was wondering if it would work. It says it is made for carburetted 2-strokes. If it will not work is there a recommendation for a fuel flow meter for my engine?
Thanks
It will only work correctly on engines that dont have a fuel return line, as some inboard and I/Os have.
I have one in my boat and am very pleased with it. The instructions are well written and Navman has a good customer service line. ( Same CS line for standard).
I set a JPG of the sender installation to your email from the profiles section. Get my email and advise if you dont receive it.
You must have some kind of filter ahead of the sender. It wont like dirt or debris in it.

Just installed my Navman F41 and I don't like the transducer. It's plastic, with transparent plastic hose barbs glued to it. And they want you to use the plastic hose clamps they provide, apparently to keep you from over tightening a metal hose clamp and damaging the plastic hose barbs.
I've got a sterndrive boat so I'm kind of paranoid about fuel leaks.
Warranty requires you use a 1-amp fuse but they don't provide one. The unit doesn't come with any mounting bracket for the transducer either.
Just got back from my first trip with the F-41. The Navman fuel flow meter worked for a few minutes and then took a dump. Either that or my Trophy just ran 82 miles on .6 gal of gas.
The meter was installed EXACTLY as outlined in the instructions and I installed a new fuel/water separator filter between the tank and the transducer. Meter reads 0.0 at all RPM, I checked everything in the troubleshooting chart but no good. It's dead.
Pretty sure it's the transducer but because the wire all the way to the meter is intergrated into the transducer you cannot check the wires for continuity or replace just the transducer. Crap.
Glad I didn't buy the Navman chartploter too, deciced to get a Lowrance Globalmap 3200 and it worked great (first run out with that also)
I guess it's possable but I installed a new Merc fuel filter before the unit and all new fuel hose at the same time I installed the Navman.
The troubleshoot guide says to disconnect the hoses and blow through it to hear the turbine whine, I did and it did. Still 0.0 no change.
If I move the wire around near the transducer it works occasionally but the wires are "potted" sealed where they enter the transducer so it looks like I'll have to replace all of it.
Just doesn't look like a durable or well thought out design to me.
Super results with my ff41. like leparker, accuracy of 2/10 gal over a 50 gal fill, repeatedly. Very poor before calibration however. I've installed or helped install two navman units and no problems either...
I have one as well on a 150 Ficht. Before Calibration mine was really of by up to asmany as 20 gallons. After the first calibration it is around 2-5 gallons. The more often you calibrate it the more accurate it gets.

Got it in the mail and put it in. A true no brainer to install- mount it vertically behind the fuel filter, run the xducer cable to the dash and wire the power w/ a small inline fuse.
Total time was about 15 minutes, with the bulk of that on the "measure twice" aspect of it.
Going to calibrate it this week. So far so good though, I certainly like what it offers for the money, especially compared to the Yamaha fuel management pieces!
Getting ready for my first calibration. But, I do not understand the reason for step 1 (Reset total log value to zero, and then in step 5 return to current total log value?
Navman F41 fuel meter, experience?
