2stroke V 4stroke consumption chart

Makes interesting reading - I know it is specifically on Suzuki but the general rules will apply to all outboards.

It shows that a 4 stroke REALLY scores at idle and lower speeds - as the throttle opens further the advantages start to reduce - flat out the figures get much closer.

Still dreading the figures for my DT225 though!!!

Is that why you keep postponing delivery?

Interesting.

Good one. Puts everything in to perspective.

I shall be studying it intently.

I think that, the comparision chart is a load of crap ... its comparing 10-20 year old two stroke, designed engines to the very lastest four strokes.... I would love to see the comparrision between the latest HDPI, E-TEC or OPTI , to the new four stroke , it think the difference would be a lot closer, In fact it may sway the other way , in certian instances, if you add in the speed of the Boat too !

Precisely! It's Suzuki saying, oh bugger we've put all our eggs in one basket with 4-strokes and completely neglected to develop a direct injection 2-stroke like our more forward thinking competitors.

theres a comparison between the etec 250 and verado 250 about half way down the page on this site.#

verado has slightly better fuel consumption at mid range speed but drinks it alot faster than the etec at higher speeds.

We have also noticed that the etec does drink about the same amont of fuel beween 3500 and 5400 revs and WOT is slightly higher at about 30% increase

Well I thought it would be usefull - obviously an etec would be even better but I couldn't find a chart comparing an etec to a modern 4 stroke!!!

The whole debate is a load of crap, if you can afford a 225hp you can afford the petrol to run it,wether its a 2 or 4 stroke - end of story

[Ezgoing]

Well said ratty!

As my mate says" Do your bit for the environment....burn all the petrol now."

Bollocks!!! 30gph flat out = £120 per hour = £234,000 a year - wish I earned that!!!

Why 1950 hours per year??? Remember that you will be spending most of your leisure time at the petrol pump!!!

.............why everyone seems to give a damn about fuel consumption. I have mates who drive every exotic car you can think of including the very latest four seated Maserati Quatroporte, most of them also own exotic boats and each and every one of them bangs on about fuel consumption. On this one I have to agree with Mr Rat. The caveat to that would be a commercial user - I'll let you lot off and someone wishing to calculate cnsumption for a long distance cruise. Those who bang on about it because of the cost

........I suppose you could be right, however I'm sure my good pal P D along with Jono Gorton could testify to the fact that I move in rather exotic circles - I myself only drive an Audi - but you can be assured that more often than not I travel shotgun in some rather fancy stuff. If you can't be the King at least be the Kings best mate.

Oh, such modesty! What you have failed to tell the forum, Graeme, is that it's only got one seat, an RS8 badge on the tail, and you only drive it for 24 hrs every June in France

the difference is that and exotic , car will do a minum of 10mpg , where a biggish rib will do .5mpg

Your predisposition to exotic circles is your own business. I would never judge a man for this harmless peccadilloes..

....A woman walks into the doctors surgery and advises the doctor that she's extremely worried, "every time I opens my legs I hear the Tony Cristie song, Amarillo". "Don't worry" the doctor assures her, "every cu*t is singing it at the moment"............

Or have I got the wrong end of the peccadilloe yet again

[Phil Davies]

Peccadilloes? Is that anywhere near Llanfairpwllgwyngyllgogerchwyndrobllllantysiliogog ogoch

............however, where as one often covers hundreds if not thousands of miles per year in the exotic car, one usually - and I emphasise usually, only covers a fraction of those miles in ones RIB.
