Ecotec 2.4 v/s 0360

Post by lewisdj1971 » Thu Jun 27, 2019 9:10 am

I’m thinking of getting a new boat and am looking for input for engine choice. I’ve always ran lycoming 0360’s and had good success but I’ve heard a lot of chatter about the Ecotec 2.4 engine and some builders are using them on comparable boats that run lycoming 0360’s. My new boat will probably be a 13x7 1/2 diamondback or Hamant hull set up for front driver and double rear passenger, open hull with short grass rake. The hull spec’s will be 3/16 bottom and 1/8 everywhere else. How does the Ecotec match up to the 0360’s as far as HP, weight, durability, fuel consumption?? I’ve seen a few set up with Ecotec and it seems to be very comparable but I don’t have any first hand knowledge of the Ecotec. Any thoughts??

Hopefully Onebfc chimes in, but there’s no comparison of an 0360 to his ecotec - his ecotec has far more power and pushes his boat places an 0360 wouldn’t dream of.

If you keep the 2.4 naturally aspirated then it compares well to a 360. It will make more static thrust due to the longer and slower prop, but the difference isn't massive. I wouldn't even bother comparing them that way.

So, if that's your plan, then think of the 2.4 ecotec as a good running 360 and build the boat around that premise and use it with that in mind as well.

Now...if you plan to put a turbo on a LE5 2.4 ecotec I will tell you right now to forget it. It won't perform well or hold up to that power expectation unless you build it from the ground up properly. Even built up properly they don't do any better than a factory 2.0Turbo with an upgraded turbo. And they cost way more.

Most bad ecotec experiences come from people thinking they can do it better and use a 2.4 LE5 vs a LNF/LHU/LDK/LTG 2.0T.

If you compare a turbo 2.0 Ecotec to a 360 it's really not a comparison. 360 makes low 800s thrust. My LHU 2.0 with efr6758 turbo makes a little over 1500.

edit: oops, forgot you asked other questions.

Durability wise I think they hold up well if you use the right engine for your power goals (see above). I have close to 700hrs on mine and no blow by, oil stays clean well past 100hrs of use and only two parts have ever failed on mine. Starter and the Flex plate. Both of those combined cost under $100 total.

Fuel economy is excellent. I run 50%93 and 50%e85 (aka: e50) and I average 5mpg between cruising and dry running. A skinny water cruise at 20mph or so will see close to 10mpg. I ran this past Saturday over 105miles and used close to 20 gallons. Fuel econ is very much tied to your hull and bottom condition along with weight so keep that in mind. Sure is nice paying under $2 / gallon for fuel!

Here is the boat in it's latest iteration. We changed rigging to a full aluminum cage and a Simpson air ride seating with stainless cage wire as well as added a transom cutout to lower the push point 5 inches. Boat performs very well and I have no complaints. Dave Simpson did most of the recent rigging and hull changes, I was the rivet monkey.

Thanks for the input guys!! Russ that is one nice build! When I decide to start my build I’ll have more questions I’m sure. My build is going to based around reliability and fuel economy. I hunt in the swamps of Louisiana and we can be rough on boats down here, I need a boat that can take going over logs, stumps, and bouncing off the occasional cypress knee. If I go with the 2.4 Ecotec it would be bone stock no turbo, I don’t think turbo would hold up in my running conditions, but it sounds like power would be comparable to 0360 with better fuel economy if I’m understanding you guys correctly. Do you think the stock 2.4 on a 13x7 aluminum with 3/16 bottom and 1/8 sides is enough engine? I don’t run dry much but want the boat to be capable of dry run with 2 people and small gear load. I would have 1/4” poly on bottom also, it’s a must here in Louisiana to have poly.

Sounds good. Though I think you may need to take a look at some of the videos on my YouTube channel to get a better idea of how tough the engine is. From the sound of it's your area is actually a lot easier than I am on mine. I recommend you use a stock LTG and not a 2.4 LE5.

Here is the most recent one, there are many many others.

I see that dragonfly airboat company is selling a set up with an Ecotec 2.4. Anyone have any experience with the dragonfly boats with the 2.4 setups? They have some videos online and the hull setup with the Ecotec engine seems like it does a good job I just don’t know anything about dragonfly boats and I see they are in Utah which seemed like an unlikely place for an airboat dealer.. any input welcome

Dragonfly is or was partly owned by Excel and Pemberton airboats in Floral City. Know a guy that had one with a 03something Lycoming. Got to drive it let me tell you was like sliding on ice. I believe this one was 12’ I can’t remember. Hull was stout was a nice set up and was pretty nice. I have no experience on the ecotech version.

I saw a dragonfly boat a week or so ago, think it was 13’ Aluminium hull rigged with a 90 horse subaru engine. The owner said it planes and runs excellent with 3 people and gear but didn’t run dry due to low HP. My thinking was it should do very well with the 190 HP Ecotec engine they sell with it on a 15 foot hull.

So I'm assuming you're running the tickfaw/Amite river or Maurepas area then ?

The first "modern airboat" like the ones we use today were invented in Utah. We have thousands of square miles of shallow marsh.

see below

An improved airboat was invented in Utah in 1943 by Cecil Williams, Leo Young, and G. Hortin Jensen.[26] Their boat, developed and used near Brigham City, Utah, is sometimes erroneously called the first airboat. At the Bear River Migratory Bird Refuge in northern Utah, Cecil S. Williams and G. Hortin Jensen sought a solution to the problem of conducting avian botulism studies in the shallow, marshy hinterlands. By installing a 40-horsepower Continental aircraft engine, purchased for $99.50, on a flat-bottomed 12-foot long aluminum boat, they built one of the first modern airboats. Their airboat, pictured here, had no seat, so the skipper was forced to kneel in the boat. They dubbed it the Alligator I as a response to a joking comment from US Fish and Wildlife Service headquarters that they should "get an alligator from Louisiana, saddle up and ride the critter during their botulism studies."[27] Their airboat was the first to use an air rudder (a rudder directing the propeller exhaust rather than the water), a major improvement in modern airboat design.[28]

The purpose of Williams, Young, and Jensen's airboat was to help preserve and protect bird populations and animal life at the world's largest migratory game bird refuge.[29] The Bear River Migratory Bird Refuge near Brigham City, Utah is a wetlands oasis amid the Great Basin Desert and an essential stopping point for birds migrating across North America. The need for a practical way to navigate a challenging environment of wetlands, shallow water, and thick mud helped inspire Williams, Young, and Jensen to create the flat-bottom airboat, which they initially called an "air thrust boat."[28] Designs and subsequent improvements and practical use of the air thrust boats appears to have been a collaborative effort. LeeRue Allen, who worked at the Refuge since 1936 appears to have also been involved and helped to document a history of the events.[30]

Many of the early airboats built at the refuge in Utah were shipped to Florida. Early records show it cost roughly $1,600 to build a boat, including the engine.[28]

Over the years, the standard design evolved through trial-and-error: an open, flat bottom boat with an engine mounted on the back, the driver sitting in an elevated position, and a cage to protect the propeller from objects flying into them.

Are you running on private lease, cause I know most of that is public/wma, we had the majority of the Mississippi/Dutch bayou area leased up from I-10 to reserve canal to Bayou Tent from the early 80s to the mid 90s before the state took it from under us.
