HELP: Suzuki DF300 or Evinrude ETEC 300 on RING RIB !?

Hi folks !

Im currently running a 10.5 RING RIB with two Suzuki DF300, which run good, but if fully seated I just lack torque. high speed is good!!

Now I look into a ringpowercraft 11.3 with three engines and would like to give the Evinrude ETEC 300 a try, anyone has experience with these !?

or even better, anyone mounted one-three Etec on his rib that I could testdrive (willing to pay if absolutely necessary) somewhere in europe !?

Please help !!

Thanks, folks !

Have a look at the Mercury Optimax 300XS - it's a very light 2 stroke and also quite good on fuel. basically it's a racing engine for the consumer market - they have a very good reputation.

I would also look at the Verado 300 or the new 350 which will be out in October.

no optimax !

The optimax would be the perfect choice, but: no CE certification for Europe !!

that's a real pity...

that's why the etec seem so interesting to me ...

did you try the verado against the dr Suzuki directly ??

I know people have been using the 300XS in the UK and we are part of Europe so does it matter?

The ETEC 250 has a great name so the 300 should also be very good. I LOVE 2 strokes!!!

I have not tried the Verado but some people on this forum have - they are very good for triple engine setups as the controls are so good.

I always said the Verado was too heavy to be of use but the 300 and the 350 have a much better power to weight ratio.

I think one of the biggest problems with the Suzuki is the shortage of good props - with Mercury you have so much choice.

I find the verado has stunning grip and accelaration, ....would love to try a twin 300 verado setup ........the top speed lags a bit, but getting there is the fun part
also as codprawn states mercury have a good range of props ..........

300's

We run twin Suzuki 300's on this 10m Humber/Quinquari Offshore Wide Commercial. Obviously Cat 3 for 12 passengers + 2 crew. Boat goes well, plenty of power. Boat used for whalewatching or a 30 mile ferry run. Cruises 25 knots at 4,000 RPM using a total of around 75 litres per hour. Flat out is a smidge under 40 knots fully laden with fuel and passengers (39.8 knots was recorded) The fuel consumption at this speed soared to 180 litres per hour!)

I would look at experimenting with different props first.

Suzuki experience

HI guys

As a Suzuki DF 300 owner I have to express satisfaction with the way it throws my machine around the place. Loads of torque.

As codprawn hinted at earlier the Suzuki has the power. You just need to prop it correctly. As I understand it Suzuki UK supply a limited range of props. Talk to julie in Steel Developments who, with Suzuki Uk, got things sorted for me.There is a much bigger range of props available on the Suzuki us website. I have ended up with a four bladed which does the business brilliantly. It has meant a slight drop in top speed.

As regards controls and instrumentation check out www.brownspoint.com. They do a much better range of instrumentation than Suzuki UK. Their digital gauges are the business. I cannot figure out why Suzuki UK do not carry the full range.

best regards

Ezgoing, what sort of performance/ fuel burn figures do you get from the Suzuki DF300/ Redbay 7.4? It looks a great setup for cruising & often wished i had a redbay cabin rib when i'm cought out in the rain! Saw the clip of your rib on You-Tube! Nice

fuel burn

Robbie,

Sorry for taking so long to reply.

With the digital fuel gauge from the Suzuki US range we are able to see our consumotion in miles per litre. This has proven to be a very useful figure as it allows us to cover ground at the max economical burn rate. It is a subtle but very important difference between the Suzuki Uk and Suzuki US systems In the range 25 to 35 knots we burn at approx .7. This can range .6 to .8 depending on sea state,trim, load etc. Over 35 knots we start to waste fuel and the mile per litre rate collapses. If we drive at WOT our burn rate head towards 80+ litres per hour.

Keep in mind when considering these figures that I have the heaviest 7.4 /outboard combination with hard nose and full cabin. Check out K'ado.
