Kohler Aegis or Kawasaki Liquid Cooled

Don't have any experience with either of them. But given that it's water cooled, wouldn't the Kawasaki be quieter? If so that'd be better for night work. How much are they?

I know the lawn care industry loves those Kawasaki's,
but after this year's factory tour and educational seminars at Kohler..
That Aegis is a fine piece of machinery..
Kohler gets my vote for name if nothing else, but..
The EFI system..
should save you 25 to 30% fuel..
in one year.. that is HUGE !
..and can pay for some "soundproofing" in short order.
Did you know..
Kohler has refined its Quality control to where their failure rate in the part 2 years..
is less than .5% in a full year of operation..
That is.. 1 in every 2000 engines required warranty service within a year..
= Simply Amazing.

..just be aware.. the EFI system.. takes 5 to 7 amps of the charging system..
start with 25amps.. and have 18 left over.

I like what I am reading about the Kohler EFI setups. Why aren't more vendors selling these type of units?

I agree. I also wonder why no one is building pressure washers with Kawasaki engines. Lawn guys swear by them. Landa makes a few, but then you have to pay for the Landa name.

If you have Jerry build a unit for you then I'm sure he will put whatever type of engine you want on it.

I was so close to having Jerry build me a PW when I got out of the lawn business and sold my mower. Sadly, the money ended up just going to bills after a slow winter season. Maybe someday.

I like what I see from the EFI, but I want to see what actual real world fuel savings is. With the EFI system requiring those amp's does that mean the engine needs more power and that you need to run the engine full tilt all the time?

How is the reliability of the new setup? I understand the older setup had great reliability, but this is a new design and how does it hold up?

How does the power hp for hp line up, ie you pull the gun trigger am I going to see the same GPM and PSI?

Car manufactures have been pulling the wool over our eyes with MPG claims, who is to say small engines are not following the same thing?

Anybody with one of these chime in on at least fuel consumption and hp to hp comparison?

Kohler does EXTENSIVE testing..
At the factory seminars they were very clear..
fuel saving was 25 to 30% less.. but so far.. they will only commit to 25%.. still huge savings !
.. AT the rated load, no BS.
the ONLY thing we sacrafice here.. is those 5 to 7 amps of charging system..
..which uses maybe 1/2Hp.. which I belileve is "tuned in" to the rated capacity..
..That makes me want to see if the cam is the same on the standard 29hp as the LP29 ..
Sometimes they throw a few HP in with a peppier cam.

What to watch out for here is this ..
If the voltage drops because tyou're "over-taxing" the charging system..
The EFI system flutters, and you loose Horsepower..
..so DON'T "over-tax" the charging system.

..fuel consumption.. I believe I was told 1.9gph MAX on the 27hp EFI..
same as the 22hp standard engine, but better HP

Kohler has not got things figured out with their ethanol problem yet. The efi is going to be a nightmare. Thye two local shops here have dropped them and discontinued warranty work on them due to their unreliabilty. Same with Briggs. I ran 7 kohlers at one point but got rid of all of them.

What are you using?


Text me for info on Milwaukee event. 480-522-5227
 
We need details
..everyone wants facts.
I talk about what I see with my eyes, and what reasonably reliable people send me in detail..

Kohler has spent HUGE money on the EFI project.
They use automotive industry experience and tooling.
.. I personally, and for my customers' sake, want details to sort through,
..with technical people that are responsible for answers..
I will be consulting with "technical insiders" of Kohler and others.

Field testing by kohler, vs a real contractor testing is still not the same and I would trust the contractor more. I understand these are new and so data is really hard to come by, but to achieve what Kohler is claiming is also a big number. When these start getting onto more trucks and guys report back what real world fuel consumption claims we will see if they published accurate numbers.

I am sure you could test this claim out by putting two kohlers side by side. One with EFI, one without, same pump/pulley setup and work it 8 hours and see the results. I understand 8 hours is not a real good indication due to the short time, but at least it could give you some numbers. It would give us some facts, instead of just published numbers.

Jerry, everything I have heard and read on these forums I would say you are a very honest guy with integrity that will speak what you feel is the truth. Kohler on the other hand is a company that's primary goal is to make money and inflating a consumption claim these days is a good way to make it.

I am not against Kohler, I am looking at getting one of their diesels in the near future. I just have seen too many companies tell us one thing when it comes to consumption, only to be let down and have an expensive engine not live up to its claims. Envirospec's flyer is full of should's and would's when it comes to the consumption numbers, I am just looking for real world numbers vs manufactures published numbers.
 
Good points, Ben..
But, like I said.. I'm looking for facts, and actual test data..

95% of the postings in a forum are "opinion"..
I wish there was more example and parameter attached to these opinion,
..especially because y'all go out, and run "the same way" site after site, but..
"Defining Detail" ..to completely understand the context of the example is NEVER posted here..
Getting "crappy milage out of that crappy engine" isn't a Helpful statement to the community,
..if we don't get to see the half-plugged air filter dude never changes.

I have NEVER seen ANY "equipment evaluation post" we could actually use
.. as a case study..
Things that might seem unimportant to one person, may be severely relative tothe resultant point..
here's a few details:
What oils was used, how often serviced,
whether it is mounted in a confined space, ..causing it to run hot,
..and have a partially plugged air filter MOST of the time ?
what performance level was expected of it, .. was the pump running at full tilt
..AND drawing from a holding tank, with a wimpy filter ??
what altitude it was run at ? ..causing it to run leaner than at sea-level ?
Does it have an air filter half plugged, or missing completely ?
ambient running temperature, .. 105 degr. is a bit different than 15degr.
..both are their own problems.
is it subject to corrosive ocean-air ?
was it run with gas-diluted oil.. ever ?
did it sit (with the same fuel in the tank) for a month between uses ?
..yes, THAT can make a difference, in specific failures.
Is the engine run at 3000rpm instead of 3600 ?

..and I believe, if truth was told.. for the care and feeding of their equipment..
only about 2 people, in the entire community has a complete process-proceedure
.. in check-list form ..and perfectly managed.
I have never seen ANYone ANYwhere post "admission of guilt"
..in NOT having a hard-lined set of Process Proceedures

..which reminds me.. I haven't checked the oil in my truck for over 2 weeks :{/

there is SO MUCH the engine owner "needs" to know, and rarely takes responsibility for.
..and the MOST important guy you need to trust..
..is the service tech that has his head in those engines every day,
..with dozens or hundreds of customers like you, for a Greater perspective,
..through the greater "comparative analysis".
But.. that guy is SO rare, you have to sort through 75% superficial idiots,
..because the bean-counter at the business layed-off the "expensive" tech.

Cheap is stupid.
Old school is Smart and Sustainable.
