Does anybody have experience with Suzuki/Johnson 140 horsepower twins on a classic 25 foot Outrage? How is the performance and fuel consumption?

I don't recall seeing any reports of twin Suzuki/Johnson 140 four-stokes on a 25 Outrage.
I've read several reports of 18 Outrage owners replacing single 150's with the Suzuki/Johnson 140 four-stroke. They have all been very pleased.
That 140 has been described as a "hot 115". The displacement is 124.7 cu. in. (compared to 118.9 cu. in. for the Suzuki 115 or 162.8 cu. in. for the Yamaha F150). I've read that the actual horsepower for the 140 is more like 125-133.
User AM put twin Mercury 115 four-stokes on his 25 Outrage and reported the performance here: http://continuouswave.com/ubb/Forum4/HTML/002183.html

The Suzuki 140's, which to me seemed sold at "dumping" pricing, were popular for a short time, since they wisely attempted to fill the 115-200 4-stroke gap before the others could get their 150's out. But since it is only slightly more powerful than a 115, I would think the Honda or Yamaha 150's, and the Verado to appear in Feb, would be a more powerful, true 150 HP, purchase for a 25.
Some here have said they like twin 115's on a 25, but this would not be for me. The 25 is big hull, and can handle power and do the speed comfortably. Underpowering it, and racing the engines along at high RPM cruising speeds, makes no sense to me at all.
I am interested in even hearing how a pair of 4 cylinder 4-stroke 150's compare, performance wise, with a pair of V-6 150 EFI's on this hull

I ran a pair of 115 HP Suzukis for 3 years on a 25 Outrage. These motors do a great job. The boat runs about 30 knots @ 3200 RPM. Fuel consumption excellent, 60 to 70 miles offshore, round trip on about 70 gallon's, depending on sea conditions. The boat was a little sluggish coming out of hole with big load. 6 men, ice, & tackle, the 140's should do a good job.

I had twin 115 four-strokes on my 22 foot Outrage with whaler-drive. At WOT it would run 40 mph with 4 guys and a moderate load, but it would NOT get up and plane on one motor.
From my perspective, if a boat will not plane on one motor, twins are not much better than a large single and a kicker. The large single and kicker combination may not look as nice, and it's not quite as nice out of the hole or in a following sea, but the net weight on the transom is generally significantly lighter than twins, and the depreciation profile is much better too.
Although we'll sometimes venture out 30-40 miles for Tuna or Halibut, the vast majority of our fishing is done less than ten miles off shore, so we run short distances and then troll all day. That use pattern would allow the hours to accumulate on the less expensive, fuel efficient little kicker.
If the Suzuki 140 is really just a 125, I'm assuming that half of a twin pair will not plane a notched transom Outrage 25. What think ye?

Inelius - As as 25 owner, I cannot imagine how a pair of 115's could run this hull 33 mph at only 3200 RPM. That would translate to a top end of 60 MPH at 5800 RPM.

Using the PROPELLER CALCULATOR, I figure those pair of 115-HP Suzuki engines, given their 2.59:1 gear ratio (and assuming a slip of about ten percent), are turning propellers with a pitch of 33-inches! That is truly fantastic performance.
That calculates to about 66-MPH at 5800-RPM.
Does this mean that 400-HP of Mercury two-strokes can be out run by 230-HP of Suzuki four-strokes, and by 10-MPH?
