Suzuki 115hp 4 Stroke Fuel ConsumptIon

[Humbug1984]

Hi
Does any konw the approximate fuel consumption of the Suzuki 115hp 4 stoke engine, extra long shaft, 2008 engine.
It is on the back of a 5.8m rib.
Thanks

rule of thumb 1 US Gal (3.8 L) per 10 HP of engine at full throttle. 4 str will use a little (but not much) less. Less throttle = less fuel. So you will be using about 40 L per hour at full speed.

Generally speaking most people seem to use ~1 L/mile +/- 20% on RIBs at cruising speed.

For what it's worth...Suzuki DF90 on a 5.3m RIB...0.7litres/mile overall. Scale it up from there and you end up as Polwart says above

If you go to Suzuki Marine Website in the USA
www.suzukimarine.com
and click on any of the engines there is tab at the top of the page which takes you to 'Boat Tests'.
Full test results are given on all the engines on various styles of boats. No RIB's are tested but looking at the fuel consumption figures across all the rev ranges there is not much difference between the boat styles.
At WOT the 115 is averaging 10-11 gph (remember to convert as it is US gallons) = about 38 litres per hour at full throttle. Consumption for all rev settings is there and the speed obtained.

You can also get the same for Mercury if you go to their US Website.
