Worst fuel usage from new 250 to 300hp motors

[goona]

Hi All,

Wondering what is the worst fuel useage recorded for a motor in the 250 to 300 horse power range. It has to be a motor that is no more than 2 years old.

Regards

Goona.

He got under ya skin didn't he

Well its the old thing mate. 6 years ago he said buy a Johnson instead of a Yamaha. Wishing I didn't do that now as the Johno is a disprin whilst my mates identical 15hp but in a yamie is like brand new and he treats it like Sh_t. Shouldn't have taken that advise. I think there are a lot of variables in the fuel useage such as weight, how it is driven, conditions etc so just seeing who gets what.

Haines 680 i went out in on sunday was sitting on 4500rpm doing 28knots and drinking 49lph. Suzuki 250 2010 model. Fuel flow was a bit all over the shop though?

Goona,

I did some tests with the Guys from Suzuki on several vessels and you can download the results direct from there website,
www.hainessuzukimarine.com.au
If you select the Outboard size and down the bottom of the 300's and the 250's you will find two local vessels from Brisbane used in the Test.
I can verify that I have witnessed the same tests on other vessels and the information comes straight from the ECU onto the Garmin GMI 10 screens and we have verified consumption to be exactly or extremly close to when fueling the vessels
Cheers
Nelton

42L/H @4000 rpm 25 > 27 Knots 1L/KM or just a lil better

It would have to be a Verado. They seem to have an aura of excessive fuel consumption about them.

[chop duster]

verado's only chew the juice above 4500rpm. below that they are on par with most other 4 strokes. flat out our 250 verado chews 110L/H

think it is something like 2500rpm = 25L/H, 3500 = 35L/H

A hell of a lot more than many want you to believe

I don't know about you blokes, but I was worried about 76l/hr flat stick with a 200 Opti - you can have your 250's and above..

[Donkeyzmilk]

this thread makes me feel good i got a 115,...some of those numbers are plain scary.

i promise to never worry about fuel usage again haha, but i bet they are some damn nice boats you blokes are driving!!

Makes me glad I've got my old 70hp on the back. Uses about 22L/H at 29 Knotts.
