Here's a link to a Swedish boat magazine, with pretty much that data. Suzuki, with larger prop running 57l/hr at 5000 RPM.. pretty much identical to Suzui's published data....which is pretty much in line with what us Suzuki 250 owners are finding.... Yes I can improve a bit... but 24L/Hr...? http://www.thehulltruth.com/forums/t...rt=26&posts=41 ...and I've seen a video of some Swedes in action and believe me they knew were their elbows were.....

I think you're probably right - 24 does look very low - but what matters is the boat speed vs. consumption.

I don't need to own a Suzuki to work out that figure is wrong - if you read all of the information you will see that the engines were run with the manufacturers supplied prop, so that's that theory out of the window! Besides the rev limit of a 4 stroke (I think we're all agreed that's a misprint as well) would be lower than the 2 strokes, so that would mean the Suzi would be higher up its rev range - hence the results could actually be worse for the 4 strokes making the 24 l/h even more suspect!

All of the above IMHO of course!

Agree- ish - but my main point was that the way the data was presented we can't take any useful information from it.

I think the RIB international , test is good to compaire the engines together, but the fuel consumption is way off ....... yeaterday at 5000rp our opti was drinking 60l/h and we can get it to to go to 90l/h if we abuse the laughing stick enough

I hope i am not repeating any thing but having been to the Boat Show
and spoken to all the engine people it seams this Rib Int test is now famous
if nothing else its got the makers at each other throats i/e how good there product is ,so mybe this error as been a good thing also look at the coverage
JBT as got . I would like to agree with the post that said roughly,
We spend any where beteen 30k and 60k on this type on boat/engine package and we are nit picking about wether its going to cost 50 more for a days outing.

Well when I went to Ribex I was treated better by him than anyone else there - he has also been great on this forum apart from ONE momentary lapse!!!

I totally agree Roy, the constant wittering about how much fuel an engine burns. We spend 1000's on our Ribs, 100's on running costs and then start whinging over 20 worth of fuel. In my view if your chucking fuel in the thing then your using it, the more it's used the more value your getting out of owning it. Big engines burn lots smaller engines burn less.
