Yamaha 200 fuel consumption

[Adam Younger]

Having fitted one of the new Yamaha 200's to a new 7.4m RIB -got to say how amazed I have been with fuel consumption.

For example, Cowes powerboat weekend:

Launched the boat at Yarmouth, went to Cowes. Race day we were patrolling off Cowes, mainly slow speed but a few blasts to warn yachts etc of race.

Then back to Yarmouth for coffee. Then off to Bournemouth via Hengistbury head to see part of the airshow.

Back to Cowes, stopping / waiting in Solent to see race boats back in. Also had a bit of a look round, did a quick photo shoot with a friend.

End of the day a run back to Yarmouth before coming out of the water.

Next time in the water straight to the fuel pontoon and filled up to the brim

47.5 LITRES!

certainly quite a game changer to my boating.

this was a mixture of cruising in 40 to 45 mph region, some quicker fun around the 55 to 60 mph and low speed work too.

obviously pretty pleased with how the hull is working too - a 7.4m, triple step RIB of my design.

I'm confused. Are you promoting the Yamaha or the Younger?

That's a very Impressive top speed and fuel consumption for a 7.5! Would love to see some photos of the boat!

Just thought it was pretty interesting as
- in all my boating times I have never seen anything like this in terms of economy
- distance covered must be in region of 85 miles or more on just over 10 gallons!
- also shows you can have economy with performance too.


In an ideal world it would be great to do back to back testing between different engines and then with a non stepped version of the same hull, then with a more conventional hull too.

one taken that day.

hull is a triple step - with quite different geometry to what I usually use or you will generally see. Steps not being that dramatic - but closer together giving a greater balance of lift over the steps.

I was looking at the New Yamaha 200 at the boat show yesterday, desperately wishing I could afford one.

Your experience with economy looks good, especially as they are also currently the lightest modern 200 available.

From what I picked up at the show.
New Yamaha 200 - 221kgs
Optimax 200 - 225kgs
Verado 200 - 231Kgs
Mariner 200 - 238Kgs - should this not be the same as the Verado?
Suzuki 200 - 263kgs
Honda 200 - 265kgs
Tohatsu 200 - 265kgs
ETEC 200 - Couldn't find one at the show, and can't be bothered to google it.

Shame my old Ocean is theoretically limited to 200Kgs, which is exactly the weight of my 1998 Suzuki DT200EFI.

Very impressive figures, I have a 7.5m Rib with a 2004 yam 200 2 stroke, drinks like a fish and max speed with say half fuel load and usuall stuff being carried would be about 43/44 knots, non stepped hull.

I understand that the next 200hp Suzi is 226kg?

[Adam Younger]

Interesting how things have changed with engines over the years and whilst we have some really good outboards now the increased weights can be a significant factor. Then also increased torque and in some cases propeller torque too. Another area is that with these bigger cc engines we have also seen bigger gearbox casings as well in some cases, which can have an effect on handling and speed.

All interesting and ideally means changes to design, set-up etc

Sounds like a good boat Adam. When do I get a go?

[Jason calleja]

very good fuel consumption I have a brand new Honda BF90 vtec on a 5.25 rib last time I used it a ride for around 2hrs at 27kts at 4200rpm and consumed around 35lt

Yeah, the new 4 cylinder Suzuki DF200 is 226kg to 233kg ish depending on the model. Looks like a great engine, should be good competition for the Yam 200

Hi Adam where is the fuel filler?

On my old 8.1 scorpion we could fill to the gunnels and seem to have had an an amazing run on efficiency until - it settled, burped and farted ( never at the pump or in time to sit at pumps waiting) then you could easily add another £50 till it was truly full..

Just a cautionary note from expensive experience

Slightly off topic but Suzuki 200 related..
Our new 7.4m with DF 200 appears to be horrendous on fuel.
Difficult to tell exactly due to lack of any smart gauges, and the filling issues the previous poster mentions meaning filling brim to brim very difficult.
We think it's using 2l per mile on a mixture of 25-30 knot cruising with very occasional WOT (to see how fast it'll go...). This on a trip from Portsmouth to Christchurch and back in F3 to 4, 2 persons, clean hull.

I've no experience of this engine, but to me it doesn't sound 'right'..very little V6 throaty warble, and even sounds like it's missing in the midrange. Nothing like a 200 Opti I tried.
Having said that, it pulls very hard and tops out at 5800rpm on a 21" prop.
Dealer is checking the motor with a laptop again this week.

Any advice / opinions appreciated.
