I did not floor it as I did not want my friend to fly out with my camera. Tach is reading 4400 when showed. The last 10 seconds I mash it to 5900 and a tad over 40mph. Now I never want to hear that a 115 is marginal or underpowered on a 19 again.

I like the sound of it. Suzuki is an underrated engine. What does it cruise at on the 19 Banana?

I would guess that the Suzuki is a 20" leg?
Jackplate or transom bolted?

20' shaft on a 5" setback jackplate jacked up 4.5" from keel. Engine sounds much louder in video but most of that is wind noise. Cruise is roughly 25mph at 4k. At 4400 I was doing closer to 30. It seems that unlike 2 strokes where the last 500rpm make a huge MPH gain, 4 strokes are more linear through the throttle range. Fuel consumption is the same. Many 2 strokes you find that over a certain rpm the fuel just goes out the window where a 4 stroke it gradually climbs. That probably has more to do with EFI compared to a jet or butterflies opening, etc.

Nice video.How does the boat weight compare to the 18' Outrage and do you think the 140 hp.would have significantly better performance? Peace.

That 115 does great on your 19! I had a 140 Suzuki 4 stroke on my 73 19 Outrage and the performance was remarkably similar.

I have talked with many owners with 140 Suzukis and they perform believe it or not about the same. I looked for a 140 fearing the 115 might not satisfy me but after talking with others I am glad I saved the $1000 or so. The 140's however have that cool cowl.

The weight is supposedly 1650lbs. The weight of 18's is all over the board. Most brochures underestimate the weight by a couple hundred pounds from what I hear and they are closer to my weight.

Very nice. The engine looks like it's mounted pretty high. I understand the jackplate kicks the engine out five-inches but what do you mean that it is "4.5" from the keel"? Is your propeller at keel level? I'm asking because I'm trying to get [the propeller on my boat] higher to clear a shallow pass. I am on an [unclear, perhaps means OUTRAGE 18] with a Johnson 150 25-inch shaft.

My cavitation plate is 4.5-inh above the keel.

I was involved with installing 32 140's on 16 skimmer barges deployed for the BP oil spill. Not one factory related problem with any motor. The Suzuki in-line four is a good motor.

I understand the DF115 and DF140 perform similarly.
The torque figures in the EPA records show the 140 has only a few pound-feet more than the 115, but the 140 is supposed to have more top end horsepower.
Does anyone have any experience comparing these two motors at high rpm?
Tohsgib posted 09-07-2013 11:09 AM ET (US)
Yes: the 140 red-line is 6,200 and the 115 is 6,000. Again, from what I have read here, the 140 does not act like it has 25 more ponies.

Wow That is impressive, almost snapped my neck off when you throttled her up!

Gotta be careful, that Suzuki is a beast!
