Suzi or opti? - Page 2

I am just hoping that the johnson is as good as the suzuki as its supposed to be identical.
Having read up on what Codders sent me on report, it may well transpire that the 140 is a "sweeter" engine than the bigger (and newer) 150/175.

As long as it works las and can pull a skiier out of the water it will do me.

By the way, any of you Computer nerds know how I can speed up the "hit rate "of the keys on my computer. its new and a bloody nuisence.
My spelling is bad enough and I normally ignore it if I have no spell checker, its worse when I know it and still its wrong because I hit keys too fast or hard.

My 6hp Johnzuki (the white version) is one of the sweetest small capacity single cylinder engines I have come across, so if the characteristics extend to the bigger ones in the range they should be lovely

personally I would buy the Suzuki cos black is easier to keep clean but there were no Suzuki DF6s available when I wanted one....

My thought when I first saw the specs on the new 150 was that is must be a lot less stressed (i.e. likely to have a longer life) than the 140 as it is something like 2.8 litres instead of 2 litres so the bhp/litre is way down. Time will tell I guess!

The question is though, as the 150hp is quite a bit heavier than the 140hp, would the extra 10hp make up for the weight disadvantage? I doubt it - add in the extra cost of the 150hp and I think the 140hp would be the better choice all-round. The 175hp is a totally different proposition of course.

The Suzuki DF140 will give you plenty of fun on your 6.5m RIB. I get just under 40kts at WOT (6100rpm) with a Suzuki 20in pitch S/S propeller. The engine is very quiet and I normally burn circa 15 ltrs per hour operating around the 4500-5500 rpm band. So overall it is a great engine, just lacking the extra punch of its bigger block brothers.

I am getting a ballistic 6.5 mtr with Johnson 140 on the back. is it enough for general messing about and skiing? The johnson 140 is the same as the Suzuki 140 df.

I should imagine a 100 hp motor would be fine so the 140 should be more than good enough.

Yes Stephan, it is 2.9 ltr versus 2.045 ltr but there is also extra two cylinders in 150/175.

Thank you all or your info, I am actually looking forward to getting it.
Roll on spring summer...

No - the 150/175 Suzukis are also 4 cylinder powerheads

Aidan · 18 January 2007, 22:23

6 versus 4

So it is, Hmmm, This is good news as I felt I should have gone for smooth 6.
Thank you Down Hillda,

anyone else ad to fuel consumption and prop advice for ballistic 6.5 and 140 for general messing about and ocasional skiing...

Don't agree here.

An extra 700-800 cc will give a load more torque, which will make the boat far more manageable, when playing in the rough stuff.
There's a lot written about the 140 Soozook only churning out around 127hp, which wouldn't surprise me, as it's only 100cc or so more capacity than the 90/115 motors. Also, if you read some reports on comparisons between the 150 and 175 Soozooks, the testers report very little performance difference between the two. Essentially the 150/175 are the same powerhead, but the 175 has variable valve timing.

have any experience of the Suzuki but the 140 has a lot of happy owners.

I also don't think the comparison between a 140 or a 225 is realistic but I guess that's what is on offer. If that's the case then it's a shame because the 150 Opti is a superb engine, it's also frugal. The 225 Opti is not proportionatly frugal, I found them thirsty at WOT about 65% more than the 150 and they used a lot more oil!

Apart from that they are a great motor

Hi there, thanks for info. Out of interest, what sped is your boat doing with 20 " prop at 5000 RPM?

Cypman · 19 January 2007, 09:20

Hi Aidan

At 5000rpm I am doing about 30kts, 34 kts @ 5500rpm.

Hi Cypman, that would do me for the moment if i thought I would get it up wind and down wind with a few on board.

THe Gentleman owner says that it will do 35kts which bears up with what you say, i figured it may do more but perhaps with too much messing with props.

I will buy it anyway, I am sure as I recall 35 kts is fine.

I would be concerned with the 140 only forking out 125 Hp at Prop and thus may have to consider upgrading engine.
Not to worry, there are worse things!!!
