    Suzuki DF140A fuel figures.

    For anyone that is interested.
    I spent a few days camping on Straddie and took the boat down from Clontarf.
    Kept an eye on fuel use and KM travelled so that I knew how the new DF140A is on fuel. So for anyone that is interested, heres the figures from pretty good, long test.
    not 100% accurate maybe, but i reckon pretty close.
    The boat is my Seafarer Ventura 17ft half cab (pretty solid/heavy glass boat).
    Prop is a 19P 3 blade. Possibly a little underpropped, but will experiment with that some other time.
    Conditions were pretty nice, maybe 6-10inch chop (not enough to be uncomfortable and slow the boat down) for about 2/3 of the miles, other 1/3 was glassy.
    Boat was fairly loaded with camping gear, but just me and an 8 year old, so not super heavy (about 10km was loaded up really heavy as I picked up a mate and his tribe/gear from the ramp).
    I cruised down/back (about 60km each way) on about 22 Knots and 4800RPM (there seems to be a sweet spot there). Plus running around.
    Distance travelled was 174.64km (GPS).
    Fuel Used was 79L (41L in from jerries and a 38L topup when I got home).
    Averaging 2.21KM/L.
    This was real world boating, I could have driven more economically at times (sometimes you have to show your mates who is boss), but most was done at the 4800RPM/22KT cruising speed in average/good Moreton bay conditions.

    Good figures, pretty well exactly what I would have expected.

    i take it you are just running the analog gauges, no network?
    Note to self: Don't argue with an idiot. They will only bring you down to their level and beat you with experience....

    Yeah just analog at the moment.
    Big rebuild and repower left the budget a bit tight...…
    Keeping an eye out for a second hand NMEA2000 capable plotter to get engine data on, but no big rush at the moment.
    Other things getting the money priority right now.

    Thanks for that GFord, thats great info.
    My boat is a touch longer and wider, but close and I'm down to two choices for the repower, the CT 115 Merc, or what your running the Suk 140.
    To me, compared to my big 2 stroke guzzler I removed, your figures would be revolutionary !.
    Thanks for sharing.

    No worries mate.
    Was keen to know how it went and figured that I would put the results on here as someone else might be interested in real world fuel figures.

    Re: Suzuki DF140A fuel figures.

    Those figures sound very good for a heavy boat loaded with camping gear

    My Barcrusher 615 WR with DF140 typically runs at around 2km / lt - running at 4500-4800 rpm in it's normal fishing guise .

    & he will sit in a boat - & drink beer all day!

    I will have a look.
    I know lowrance do one, but it's more like 7-800.
    There's a wifi one advertised on facebook a lot for the 200 mark (Dunno if it's any good).
    Still need to finish off the canopy, do the cabin interior and see about a new prop, so unless a NMEA2000 capable plotter comes up real cheap, that's on the back burner......

    Yeah i can't remember where i seen the one for $400 maybe it was on special i now see they are $700, My Mercury is capable with the Wifi too i think that's a really good option for u with your Suzuki u should be able to run it on a 10 inch android tablet

    I have a Johnson DF140 on a V17C - so a very similar setup to yours. I have found that I am getting a very consistent 1 nm per litre with a mix a cruising, trolling and idling. I cruise at about 4000 rpm which gives me about 20 knots

    This is was yesterday’s figures for my Bonito 5.6 and DF140A.
    About 1/6 on Broadwater and the rest offshore in pretty good conditions though not flat.
    Half the trip at 4000rpm 40km/h (this is most economical speed) then mostly 4500 45km/h, and a couple of minutes maxed out at 6200rpm 62km/h.
    Works out to be 2.6km per litre.

    Sweet.
    Pretty similar figures to mine.

    If you come across a Simrad GO7xse model they would be worth grabbing. Suzuki (in USA at least) now makes an engine interface cable specifically to allow Simrad and Lowrance displays to show full engine data plus service reminders, fault codes etc. When connected to a Navico MFD with current software, you get a customised Suzuki dashboard appear.

    So this cable allows you to do away with analogue gauges all together if you want to.

    Plus the Simrad displays have a really neat feature called TripIntel that records all trips, including a chart of your course, plus a heap of fuel and related information, as well as long term statistics. Very neat stuff.
    Note to self: Don't argue with an idiot. They will only bring you down to their level and beat you with experience....

    Cheers, will keep an eye out.
