suzuki 140 4stoke

[marios]

any advantages or disadvantages of suzuki 4 strokes?

[Alex Brown]

the 140 is actually lighter than the 115 and 90 suzuki 4-stroke engines.

it's deadly quiet, and pretty good on fuel consumption.

starts first time everytime

Hi Marios

One of the teams on Round Ireland 2002 used a Suzuki 140hp to circumnavigate Ireland in 7 days. They did complete it. You can read more at www.ribchallenge.co.uk about their journey. They had one slight snag but that was due to "dirty fuel" rather than the engine itself so its pretty reliable if you ask me.

I put a 115 hp on lto my BWM DS18 last year and am delighted with the low noise and inproved fuel consumption. It knocks the spots off my old Evinrude 90 V4.

Excellent support came from both the Dealer (Pacer Marine in Farnham) and directly from Suzuki themselves when we had an installation problem (our fault - we had used a non-Suzuki control box and the current rating of the PTT switch was not high enough). The Suzuki engineer even came out on the boat to do the fault finding at RIBEX last year. To me it's not just the engine it's the support as well and I think the Suzuki package is well worth it.

FYI, I understand that the 140 hp has lighter weight PTT mechanics to get the weight down.

Hi Nigel
This may be daft question, whats does PTT stand for in this meaning?
I know it as Press To Talk- radios etc,

Jelly,

I think it stands for Power Trim & Tilt

No disadvantages that I know of.

I have one fitted on BOB the yellow rib.

Its been getting some pretty intensive use of late for a lesuire rib and the engine has performed faultlessly.

Great acceleration, very quite, on tickover in the Marina you can easily forget it is going.

Power to Weight ratio is excellent for this class of four stroke.

In a word - DOH!
Thanks should have known that

Sorry to bring this thread back upto the top, but I am wondering if there is anyone else on this forum (apart from Martin Stacey) that has the subject mentioned Suzuki engine?

Reason is, that I am having a few problems with mine, one is a problem for sure, and the other (I hope) is just a niggle more than anything.
When running, either hot or cold, put it into reverse, and sometimes it will stop dead. It's like the engine is turning itself off. This has only happened twice when going into forward gear, but seems to be getting more frequent when going into reverse.
I was at our local Suzuki dealer yesterday, and they confirmed that the engine was running exactly as it should be - the revs when idling are spot on, and as far as they can tell, there is not a problem. They were reluctant to alter the idle revs, since at 40hrs, the engine is still running in (?!?!?!) - they'd be more inclined to adjust it at the 80hr service mark. So, in the mean time, as I come into the marina, or come into drive the boat onto the trailer, I have no way of telling whether it's going to die on me, as I try and stop - this so far has caused some embarrasing berthing movements.....
Also, I think this is more of a niggle, but I am failing to get anywhere over 5800revs. With 1 person on board, no tide, and light fuel load, I am maxing out at just over 38knots at 5800revs. Pile 4 adults on board, full fuel, and 5800revs once more, 38knots...... The prop is the default 21" x 14" ali prop that came with the engine. Apart from Martin, is the 6200rpm mark actually possible on the boat? - my rib isn't too much heavier than the ribcraft 5.85, so I can't understand a 400rev drop.
I'm just interested to know if anyone else has had this kind of experience (or problem), and if so what the solution was, before I ask Suzuki......

Thanks,

-Alex

Alex,
I mentioned earlier, I had had some problems after installation due to us fitting a non-Suzuki top mount control box. Is there anything in the engine installation that is non-standard Suzuki? The currents and technology that these 4 strokes use does seem to be a level up from older 2 stroke tchnology and our experience with the Dealer trying to fault find the Suzuki was that you have to revert to their standard installation to have a chance of finding these intermittent issues. The problem we had was unrelated to yours, however, so good luck in finding the solution.
