Fuel economy of Suzuki 200

[Any_Weather]

Gday guys, this was just an informative message with real life figures for a pair of DF200APX. 2 weeks ago we did a trip to 1770. We hit the ramp at midday Friday and returned at midday Sunday. We went to Broomfield and had good weather on the Friday and Saturday and punched home in some ordinary seas. We were very heavy for the trip with full fuel (540 litres), 200kg ice, 4 blokes, and supplies for the weekend. We did a total of 349km for 356 litres of fuel.
Another local trip here on Thursday with only 150 litres of fuel on board and ice for an afternoon and 2 blokes showed my fuel consumption at 1.3km per litre.
Both of these trips are a minimum 20% better than the previous 2013, pre lean burn DF175’s I was running.
I am running 4 blade, 20” props.

Cheers guys
Lee

Fantastic Lee.

What brand prop did you use?

How does this fuel consumption compare to other outboard motors you have used?

Little confused.
"349km for 356 litres" : 349/356 = .98 km/lt

What boat are the Suzukis on? What’s the rough weight loaded?

Little confused.
"349km for 356 litres" : 349/356 = .98 km/lt

Or about $2.20 / km ::)

that was the first trip but the second one on Thursday came in higher at 1.3, don't know why that would have been the case but then Lee goes out in any weather and Thursday might have been sloppy although it looked pretty good while I was having coffee overlooking the new bar.

Sorry guys, Thursday was showing 1.3km per litre.
Splash, the props I am running are solas props off my last engines. I had them cupped for more bite on the bar in aerated water.
The boat is a 7.8m Riptide and i think the loaded boat on the water without trailer would have been somewhere about 3.5t

Splash, yeh compares pretty good. My last boat was 6.5m plate with F150A yamaha and when fully loaded was working pretty hard and only getting the same sort of figures. With a light load it was good for about 1.5km per litre

Pretty good figures for that lump of a boat...is it 2.7m beam..?

[Any_Weather]

No not 2.7m beam, still just 2.5m. They go to 2.7m from anything bigger

Lee, have you put an order in for your new one yet?

[Any_Weather]

Gday Sam, yeh I did at the beginning of May. 3 years waiting. I won’t sell mine until the new one starts.

Thtt's pretty good. By calculation that equates to 1.425l/nm. My single Mercury 150 4 stroke runs 1.6l/nm full throttle fully loaded, but cruise is normally 1.2 l/nm at anywhere from 3850 to 4500 rpm, which equates to 19 to 25 knots. I CAN get 1.0--1.1 l/nm, but you are only running at about 17-18 knots, and who's got time for that ;D Of course, this is pushing a heavily fitted out Caribbean Reefrunner, so I can easily be 2 tonne in the water. I don't think that going to a V6 200 Merc, or even a 200 Pro XS would see me using any more fuel on the cruise, due to better power/weight ratio. Have spent some time on a mate's 2300 Caribbean, with 300hp Yamaha, which weighs well over 2.5 tonne in the water, and the 300 gets similar figures to what you are claiming, about 20% more than I am using in the same conditions.
The modern versions of the 4 stroke are certainly good.

Solid numbers Lee, you would have to be happy with those i recon, thats solid hunk of boat!! The old Rippa is pretty efficient hull through the water to i think, on the flatter side, doesn't drag any huge inbuilt chine. We were up there the same weekend out of Sykes. My numbers were 1.1km per litre, 6.8 20 degree model with 170mm of chine, twin 140's but i only had myself and my 11 year old on board.

Gday Scott, yeh that’s good economy also. I did see a number of Riptides up there that weekend. Is yours a reasonably late model with the 20 degrees?
I am very interested to hear how the later ones compare to the older ones in both ride and economy?

Cheers
Lee

Lee, my boat is a late 2020 build, not as efficient through the water as the traditional shape in my opinion (everything else kept equal) With 20 degree deadrise and 170mm of inbuilt chine there's a bit to get mobile and keep mobile as compared to the tradional ones. I went the 20 degree kit because i could only fit 6.8 in the shed, figured given i wasn't up in the 7's for length i'd need some deadrise to get some ride. Its a great boat though and i get about 1.1 km/l witht he twin 140's under most conditions, running 3 or 4 adults versus 2 starts to make a difference fast though. i recon once you get up over 7m wheelbase become more of a positive and nothing beats length, hence all those big 7m+ rippa's out there with 15 degree or a bit more deadrise hulls just seem to work, can carry weight really well without buggering the economy. I'm no boat engineer but thats the way it seems to me anyway. Note Dave is building himself a new prototype, 18 degree hull with an inbuilt chine so will be intersting to see how that goes. 8m one i think.

Thanks Scott, yeh I will be keek to see Daves. Weight is my biggest restriction.

Cheers
