it's about 30-35kgs more weight for the 60HO (3 cyl) Vs 60 (2 cyl)Originally Posted by chris69

Which is why manufactures put a hp and transom weight figure on their hulls

Because HO motors are NOT that much extra HP, regardless of Internet stories, HO outboards produce power at a different stage, have different gearboxes and some other "stuff" the e-tec 90 being slightly different in so much as it is a V4, over the standard inline 3, making the power band/torque curve different, but max HP still falls within the allowable limits, can't get much simpler than that.
DF suzuki 60HP 104kg that's 41 kg lighter than the 60HO there's no point putting a heavy 60 up motor on a boat when you could run a 75hp for the same weight and motor.
seems like engines need to have a torque figure at a given rev range on the cowling instead of a HP figure!
I think you'll find that an Etec 90 is an inline 3 & has the same displacement as the 75
The 115 & 130 are the V4s

I wouldnt base it all on cylinders and so much the displacemnt look at some of the old 50hp 2 strokes were 4 cylinders i think the mercury 115hp was a inline 6 cylinder modern engines have somewhat improved in efficinecy
the old 4 cylinder 50 mercs use to smash the 50hp evinrudes for performance!
Later Merc 2 stroke 100 115 & 125's were 4 cyl with some of those 2 + 2 engines.

yeah i could handle a new Etec, never had one before. its a no brainer just looking at them , they look so damn filthy good , and on paper it would appear they are advanced in outboard tech. even the four stroke lovers got to agree you secretly love them too.

The H.O. designation can mean up to 10% more than the engine’s stated horsepower.
High Output Means Higher Horsepower
The 10% Solution. The Society of Automotive Engineers (SAE) lays down the standards and rules for horsepower ratings. The SAE, says that if on a dynamometer, an engine comes within 10% of its stated horsepower — no harm, no foul. That means an outboard that says “100-hp” on its cowling can put out as little as 90-hp on a dyno and still be within SAE specifications.
H.O. Means More. These rules also mean that a 100-hp engine can be 10% over its rated horsepower and still qualify as a 100-hp engine. This is how Evinrude came up with the H.O. designation. In the case of the Evinrude E-TEC G2 250, the horsepower is actually closer to 275, which is why there is no Evinrude E-TEC G2 275. Evinrude is not “guaranteeing” 275-hp, it is just saying that it is “higher output”. We could not pin down any Evinrude tech on exactly how much horsepower the engine actually produces. They would simply say, “It’s High Output”.
H.O. Applications. All outboard boats have USCG maximum horsepower ratings. The E-TEC G2 250 H.O. is obviously a way to meet the USCG requirement, but also to provide an extra punch. Tournament bass fishermen will like this little advantage.
We tested the motor on a Ranger Boats Z520C bass boat. With the motor turning a Raker 14 ˝” x 26” three-blade stainless steel propeller through a 1.85:1 reduction, we ran 71.7 mph at 5700 rpm and burned 22.1 gph, giving her a range of 131 miles. Best cruise was at 3000 rpm where we ran 32.5 mph and sipped 6.5 gph, providing a range of 203 statute miles.
We felt the torque of the 2-stroke in acceleration tests. The boat planed in 3.8 seconds and ran out to 20 mph in 5.3 seconds and to 30 mph in 7.1 seconds.
Another boat we tested was one of the heaviest in class by several hundred pounds. Yet, when we tested her with the Evinrude E-TEC G2 250 H.O. she turned-in WOT numbers that were as fast as lighter, smaller boats in class that were also powered by 250-hp engines. So what could have been a disadvantage for the boat builder – a heavier, slower boat – was mitigated with the extra power provided by the Evinrude H.O. engine.

IMO after reading this, I would say that HO series is a high powered motor and a little bit of advertising genius used.
Within the article outlined above it says
“Evinrude is not “guaranteeing” 275-hp, it is just saying that it is “higher output”. We could not pin down any Evinrude tech on exactly how much horsepower the engine actually produces. They would simply say, “It’s High Output”.
Make your own mind up and if your worried, check with manufacturers and insurance companies and request their decision in writing.

That was from a boat test website, advertising, nothing more, nothing less, almost every Mercury owner and internet reader will state that Mercury underrates their engines, some even sprout huge numbers of "extra" HP than the sticker denotes, the same internet myths state Suzuki's are "weak" all Honda's are heavy, and there has never been a Yamaha problem ever, most e-techs will probably blow up before you start it, and similarly,HO engines have extra HP, these statements just continue on, year after year, until they become common knowledge and "truth" because someone read it on the internet. HO engines do offer added features and power band that suit certain applications, I really doubt if you buy a 200HO and install it on a boat with a max rating of 200HP that you will be fined for exceeding manufacturers specifications.
I don't know about secretly loving them ……. Gen IIs continue to be problematic - it appears to be a case of Roll the dice & see what you get.

I reckon I have owned every brand in all sorts of HP over the years, and I certainly have had every operating principal, some were good, some not so, the only brand I have never owned is a Chrysler (I think) had DFI, FICHT and e-tec, had EFI, Suzuki and Yamaha, had carby, Mercury, Yamaha, OMC, Tohatsu, even a Victa mower motor outboard, had mix your own and oil injected, all had good points, some had "issues" that kind of soured the experience, but, overall, none were "bad" as such.
Um no
Not everyone wants one
You’ve never had one but love them
Marketing at its finest, they should be given medals
But I assume your post was said In jest and lathered with a bucket of sarcasm
