You probably wouldn't need a tacho to indicate the Suzy was pulling 8100rpm, I would think the fist sized hole in the engine block would be a give away.

It wonder why they didn't test an Opti. It might be good to do an Opti Etec test.

I't might be a cool idea to get the specs from the manufacturers and post em in the ref section of te forum.

Now If I may be a little less serious

Mr Ged (sounds like a torking horse) don't take any nonsense from that Manning fellow give him the finga

It was a test for 250hp engines.

Would you like to borrow a book on anatomy?

I've got all the specs in spreadsheet form. You can borrow them if you want. They're in a tupperware box.

[QUOTE=davidmanning] Dunno what you're laughing at Mr. GED.

The Etec results are horseshit as well.

who cares its got to be less than im burning in my 200hp now!
and what arse from his elbo would by an engine on its peformance/fuel economy any way!... My new engine looks pretty and thats good enough for me.......fuel economy is for pipe smokin retired people........

Spot on! Spend £30K plus on a toy then worry about how cheap to run it'll be.?... go figure...

I agree Ged, so much stuff on here re:- "how much fuel does it burn?" Unless you're a commercial operator, what does the odd litre here or there matter. Ribs cost heaps to buy and run, if you're gonna fret over a bit of fuel, don't buy one.

( i think you know what that's supposed to mean)

I would be interested to see how well a 225 opti would stand up to those bigger emgines. I can tell you that at full chat pushing a 7.3 Gemin1 I was burning 98 lph but it was worth it

Just read the thread from start to finish and quite surprised at you lot having what seems to me as an outsider as quite a pop at 'Riva'.

Firstly Rib International is a small specialist magazine (Wahay!) and therefore has to operate on a budget rather than having engines justs ent by the nearest PR company etc.

Riva to me is a hugely respected member of the RIB industry and when I have spent countless hours picking his brains, chewing the fat and generally hearing his thoughts on ribs, engines and the boating world, he has never be too busy and has actually always given me independant advice on the best way forward.

So my message is if someone if prepared to help out and spend a wet day in the Solent messing around with guages, timing runs etc. and I suspect he got no personal reward for it then good on him I say!

So maybe a bit more discussion and a little less slagging off might help! Anyone would think we were talking about Codprawns rib the way this thread is going!!!!!!!

RIVA - keep up the good work

Ive seen your engine standing in the shop yeah it looks pretty good

Milan · 11 January 2006, 09:28

Agree with all the comments on this fuel bulls**t if I had half a brain I would not have bought a boat in the first place what really interests me is this report on he Tornado rib cant get a copy of RI. round here for love nor money would some kind person possibly PM. me and perhaps furnish me with some details

I wish somebody would say something nice like this about me.........Just the once. that's all I ask!

In answer to your question No I don't think it was a personal attack on Riva, and no I don't think he took part in this test purely for altruistic reasons. he sells boats and surely any publicity generated for JBT is good.

the attack was mostly on the errors in the article

Perhaps you need to re-read the posts and see where the "slagging" originates, before you start advising others how to behave?

I think there are people out here who have quite a few hours on the Suzuki engines..... and when one of them questioned the results he got the above abuse.. So who's doing the "slagging" ?

The fact is.. redline 6,100... fuel closer to 60Lph than 24..... I don't "think" it, I......and others ....know it.. because we use these engines.

Why the feck' do we need to call Suzuki.. I can walk 100 yards and put my hand on my engine.. I know it redlines at 6,100....

All I can say to you is God Help you if you have a technical problem that needs RIVA's input. If he can't spot a glaring mistake on RPM limits and a probable 100%-200% glitch in fuel consumption tests, or even react in a reasonable and civilised manner when it's questioned, what hope do you have?

Right, here we go,

Have kept quiet up until now as I had not had a chance to read the article until this morning.

The article I found dissapointing because it looked like the testers had spent a lot of time and effort doing the testing but all of this was let down by the poor presentation of results.

The 24l/h for the Suzuki could be correct - we don't know what the boat speed was. If the propeller that was fitted had a short pitch, the boat speed would be low, the engine lightly loaded and it could well not be using much fuel.

Also, the engines have different WOT speed ranges - so, if correctly propped the boats would be doing different boat speeds at each RPM increment - 4000rpm for one engine could bear little relation to 4000rpm on another.

What would be really useful would be to know the mpg (or consumption l/h) at different boat speeds for the different engines.
How far I can go for a litre is what is important.

I'm sure the magazine has the boat speeds for the rpm increments and the corresponding l/h.
This could be plotted graphically, speed (instead of rpm) along the bottom, l/h up the side, superimpose the curves for each engine on top of each other then we could see what's going on.

It looks like Paul, Jan, Kieron and Jason have had all their hard work and time wasted because the Journalist didn't know how to present technical information.

Would be good if the magazine could re-print the article and present the results properly.

PS I think Rogue is great - have a Brownie point from me
