Author Topic:   1994 Outrage 19 II Re-power

I have a 1994 Outrage 19 II [ready] to repower, ideally with the E-TEC 150 H.O. But I see it only is built at the 20-inch shaft model. Not enough for my boat. Also, I hear those motors are made for the bass industry but don't know why it would [not] scream on the back of my Whaler.

No, the 150HO has been offered in a 25" shaft version since last year - although only in a graphite cowling, not the white that goes well with Whalers.

Oh, I like the graphite against the white whaler models. Thanks for the information. Now do you have an opinion on the H.O. or standard? I was told the H.O.'s really perform on the lighter base boats but not made for the heavier whaler hulls--doesn't make sense to me as more horsepower is more horsepower.

Depending on the particular model of E-TEC, the designator H.O. can mean a different gear case design. Certain H.O. models use the Lightning L2 gear case, which is intended for really high speed running, over 50-MPH,, while other H.O. models use the Magnum M2 SLE (straight leading edge) gear case, the same as the standard models. It varies with the particular model.

There was a time when the H.O. designator always meant more horsepower than the cowling decal, but I believe that in very recent models that may not always be as true as in the past. I believe the power ratings were affected by some considerations for compliance with the most recent EPA emission testing requirements. The EPA added new limits on exhaust emissions by imposing regions of operation where exhaust emission was No To Exceed (NTE) certain bounds. I have a hunch that this may have caused Evinrude to modify certain H.O. tuned E-TEC engine to comply with the NTE regulations, and the result may be that they don't come with as much extra power they used to always have.

I don't know why people think a bass boat is necessarily lighter than a Boston Whaler of about the same size. Those bass boats are full of gear, live wells, batteries, pumps, carpeting, and who knows what else. A classic Boston Whaler center console with not much added probably weighs no more--if not less--than some bass boats of the same size. It is the relatively flat bottom of a bass boat and the huge engines on their transoms that allow them to go 75-MPH. If you put 250-HP on an OUTRAGE 18 it will go scary fast, too, perhaps too fast for the hull's design.

Whaler with a graphite E-Tec for your reference.

I would go for the HO, that way you will never wonder if you should have sprung an extra $1000 or so for it.

You're right - horsepower is horsepower. Although the HO designation and different graphics may be designed to attract the typical bass boater ("and it goes to 11!") there's no reason the extra power won't come in handy on a real boat as well.

If I was repowering an 18, I'd certainly be thinking about the 150HO. Evinrude's website has it at 418 pounds in the 25" shaft - very light.

Jim, what information has brought you to your conclusion that the HOs have been watered down? I'm sure it's technically possible to do so via a simple software change.

I would be interested in aftermarket chip change out.

Probably not as simple as a chip change. It would likely require an ECU/ECM remap. I don't know if anyone is offering such a thing for E-TECs. A Verado ECU can be remapped for a lot of additional power and there is at least one firm specializing in just that.

Making any changes like that would probably void any warranty and the changes would almost certainly show up when a dealer hooked up any diagnostic software to the engine.

Evinrude published some technical information about their engines which mentioned the EPA NTE testing procedures and the impact they had on engine tuning to comply.

I generally give the most authority on horsepower rating to the "CE" sticker or mark. ("The CE mark, or formerly EC mark, is a mandatory conformity marking for certain products sold within the European Economic Area (EEA) since 1985."--Wikipedia). The CE mark appears on E-TEC engines, and gives the power in kiloWatts and the weight in kilograms. Convert the power to HP from kW, and you will have a reliable power.

In the way-back, my memory says that the kW power would tend to be higher than the cowling decal power on the H.O. models, but I don't think that trend has survived this latest EPA NTE testing procedures.

There is no possibility of a "chip" affecting the E-TEC EMM fuel maps. The EMM circuitry is embedded in a potted enclosure; you can't change any chips. If you could understand the Evinrude engine firmware, perhaps you could write your own files and upload them to the EMM, but I have never heard of anyone accomplishing this. It is much less tedious and probably less expensive in the long run to buy an engine with more power than to try to make up your own engine firmware and boost a lower-power engine.

Jim, is the information only located on the CE mark on the motors themselves, or is there a compilation of it someplace, so one could compare years? At some point in the moderately near future I would maybe be interested in an HO motor, but not if the only difference is the cowling.

I do not have or know of any sort of compilation of that data.

As already discussed, there are physical difference in some H.O. models from the standard models; the gear case, for example. There are also differences in the fuel map stored in the engine controller.

I would personally put on the Mercury Optimax 150 Pro XS, I notice the Etec website won't do a comparison to that motor. My neighbor changed his 150 HO Etec on his East Cape Vantage, to the Pro XS and he picked up top end by 5 knots to 61 mph. The merc will push to higher RPM, and he told me it didn't seem as high strung as the Etec. Plus he said he didn't enjoy the induction noises the Etec made.
