Engine tests (RIVAs ballistics)

Hi all

Was just reading a section in RIB international about the engine tests using RIVAs Ballistics. As the report states in its conclusion, the engine you choose will probably come down to Price +++ other factors.

******

However, I am not sure myself I would notice the difference to 30 knots looking at the figures, in-fact unless I was racing Iím not sure the few second extra by some of the engines would make much difference to most users

Price-wise the Suzuki looks the cheapest by 1300 quid. Servicing the ETEC seems the obvious best, however second place looks a little in-conclusive as I donít know the cost of servicing.

Economy, looks like Susi is the best but gets closer as the revs drop <4000. The Verado thatís looks expensive to run if you do a lot of high revs.

When I first joined Ribnet, it seemed a lot of people would go for Mercuryís, now it seems much more equal, what do people think as this is an interesting subject as the cost a lot of money.

I suppose it could depend if you can get a "deal"

It seemed to me to be open, depending on certain factors e.g price


However the Suzuki was the one i would go for(if i was buying one), until i read the servicing then i was not so sure, i dont do 100hrs in a year so it looks like you have to service every 6 months.

Personally, I wouldn't place too much faith in the quoted figures because of the use of four different Floscan units instead of accurately measured fuel containers for each run.

Apart from the fact it states the rev range of the Suzuki is 5-8000 instead of 5-6000, the fuel burn at 5000rpm is said to be 21lph against 72lph for the verado.

The Suzuki 250 I've driven this summer uses more than double that amount at that rpm.

HMS really stuck his neck out in the latest issue. He says that the build of his Tornado, and Trident dry suits are crap.

We did use the same floscan unit on all four boats. The feed was taken from the same position in the fuel line on each boat so the figures are pretty fair.

its a hard choice , the test was fair and exact to each engine . and it would be better if people did not think they knew there arse from there elbow . and asked first

just one point they all had 250lt on board

my personal choice for driverbilaty would be the verado .

for value for money the etc and suzuki

and for re sale the yam

and all stats were supplied by the manafacturer not a dealer

the prop trials showed a masive diffrance 8.5 knots more on the yam if you proped her for speed , but they were all put back to the prop the manafacturer would supply stock

It was a good article, with a 50 mile round trip to my local service centre the E-Tec looks like a good buy off set by servicing costs; however the Suzuki fuel consumption was very interesting if Petrol prices continues to climb.

I have seen a spread sheet from Scorpion from when they do the sea trails on the new boats all the same lenghths
It showed that the Suzuki was the quickest by a fair margian
and that all the others Etecs Yamaha Mercury etc etc
where within 3/4 knts of each other. as for fuel figures
I had a Yamaha fuel flow meter fitted on a Yamaha 225 f/stroke and at 5000 rpm on a flat sea it would jump from 14 gals an hours to 16.
Why dont Rib Int do what Autocar do on there tests
and give there opionion what they would have there choice. its not always popular, or is there an old boys network , dont want to upset any body because they might need to loan a boat later in the year.
