Will be interesting if this 7.3l makes it into a wakeboat.

Personally prefer a ďcam in blockĒ vs Overhead cam.

Like the 6.2, but this could be the next Ford boat engine.

Ya definitely interesting that they went back to a push rod!!

Also interesting that they are going to carry the 6.2 over as well. I wonder how long they will offer both...

interesting. I would bet the larger block will be short lived in trucks and switch to the rv industry like the old v10 ford had.

It will be used in super duty but also the larger medium duty trucks.

Iron block pushrod engine makes perfect sense in a wake boat.

Yep, who knew a pushrod V8 would make more power and be more reliable?!? Lol
If Indmar gets ahold of the new 7.3L and it becomes an option in the new SA, I’m gonna be first in line...

Great...... Just when I'm trying to get a new boat built. My luck I'll get a 2019 and then for 2020 they put in the Godzilla engine :eek:

I would doubt Indmar would be moving that quick on a new motor when the 6.2 is still being produced.

I assume companies like this get the Ďheads upí when Ford plans on sun setting, so they can get enough testing and r&d completed.

I could be wrong . . .

Iím not a Ford guy, but I thought that 6.2 was released in the Raptor pickup 8-10 years ago?

SC started using them in 2015. So this would be the 5th year. That is not too long.

Cool read and the future sounds interesting!

Mustangs have what 3 cat converters on each side for emissions on a 5.0 Iím curious to see how theyíre going to keep emissions in check with this beast. Itíll look like a diesel dpf system under the truck lol

The reason indmar switched to the raptor 6.2 is the availability of blocks. When Ford moved nearly all F-150 and raptors over to the ECO Boost and 5.0 it left a huge inventory of 6.2L blocks that could be had for cheap.

Itís all speculation of course, but even if Godzilla get marinized , it wonít make be disappointed in owning a raptor at all.

Looks like the small ecoboost got picked up by Indmar.

I saw this yesterday too. May be opening the door for the 3.5 in a wake platform maybe.

Looks like the 2.3 EB is planned for wake boats......

350ft lbs and 310hp is impressive out of a 4 banger, but, itís awfully light weight.

Still prefer a iron block V8 for several reasons but one reason is free ballast.

I guess the engine bay would be smaller and allow for bigger bags......

I would hope that indmar has many hours of testing in real world applications prior to this announcement however I would have 2 main concerns and want several years of testing before I would buy one:

larry's comment above about smaller engine bays- turbos create heat. lots of it. would it really be smaller or taken up with either space for cooling or more radiators to keep them running chilled

and turbo spool. as the skier yells "hit it", what will that spool look like, especially slalom. twin turbos of differing sizes typically yield less turbo lag so interesting that they chose a single vs something like the bimmer inline6 that isn't so laggey.

one benefit tho would be a platform that the tuning community has an aftermarket for. it could open up options to move from 350hp to 450hp with some simple add-on's and tuning might not be proprietary anymore.

Based on indmarís history of locking ECMís I expect zero aftermarket tuning ability.

The eco-boost 3.5 has very little spool, if any. Max torque at 2000 RPM. I have it in an exclamation itís awesome. Very impressive if you asked me!

Edit: Sorry I didnít realize the 2.3 was a single.

This article says Indmar plans to use the eco boost in a .....drum roll.... Jet drive called the "Ecojet"! https://www.tradeonlytoday.com/manufacturers/miami-2019-launch-ramp2

I sure hope they don’t put an eco motor in a wake boat... I just don’t see how they’ll control the heat from the exhaust housings and down pipes. The regular 3.5 can make them glow red in a truck, not including the overboosted Raptor. Plus the boost spikes every time the boat hits a wave... I just don’t see how they can account for that when the boat is loaded down in the tune.
I was talking about it with e of the Rinkers guys this evening, I see lots of warranty claims and burned up boats in the future.

Thatís why marine engines utilize water cooled exhaust manifolds.

I would sure this would be pretty well thought out before it was ever put into the field? I doubt we just toss one into a boat and light it on fire.

Glowing red hot metal and water don’t mix. And the exhaust manifold isn’t the problem, it’s the exhaust turbine housing and down pipe. To make these EcoBoost motors spool so quick, they use a tiny housing. Unfortunately that leads to a high drive pressure which makes extreme heat.
I’m not saying it can’t be done, I’d just need to see it work for a few years before I bought into it. You’d have so many water lines running thru the boat to keep everything cool, I feel like packaging would be an issue.
I’m all for ways to save gas as much surfing as we do, and I have no doubt this is where the industry is headed. I just wish boat makers would stop following automotive trends. Build a boat that works and people will buy it.

Just remember, FoMoCo ‘tested’ the 6.0 and 6.4 power stroke for years (and decided they were good?!?), as replacements to the 7.3. They were the worst, most unreliable motors in history. Lol
The EcoBoost doesn’t have a great track record yet either. High strung turbo motors don’t last, never have, never will. I hope indmar puts some time into it... otherwise I see nothing but warranty claims in their future.

broke, depends on the application. 4g63 in mitsu's can take up to 34psi from factory(ask me I know :) ) with nothing more than replacing the head studs with arp's and are known for well north of 100k miles if you change the oil regularly.

I am 100% in your camp tho that I don't see them as a long term solution and think it'll be a fuel economy play that will be a fad. I think i'd have to see 5+ years in a boat application with success before I'd pull the trigger.

what I don't get is the claim for greatly reduced install times. maybe on the repair side with more room to work around but most manuf. are installing them early in the process where the cavern is wide open. might save say 5min a boat in a few less nuts and bolts but bet most manuf. would find more efficiencies tightening up long break times from workers than savings like this..

Most 6.0s ran without a hitch. It was not nearly as bad as the world makes it out to be. Lotta hype. But they did come up with some bad problems for the unlucky ones.

My friend runs a diesel performance shopósays same. Lotsa ďbulletproofingĒ happens even though the motor was fine. My dad heavy hauled a few 6.0s with zero issues. But what shall be shall be. I have personally loved the 3.5. Itís a marvel. But there are issues with the first gen motor, on fairly infrequent occasion. Now they mixed the fuel injection which takes the buildup issue away. Theyíre strong little motors.

I am just sayingóboats on fire? I would think turbo cooling would be engineering issue number one. Youíre driving around on a huge cooling reservoir for Peteís sake!

But everyone will poopoo the idea.

Small diesels would be neato but there is zero diesel fuel on the inland water.

Anyway, I think the future will be pretty damn cool to watch!

Most ecoboost issues are timing chain tensioners making noise (corrected around the 2015 model year) and condensation building up in the intercooler (corrected about the same time). The motors themselves are pretty stout and really the only ones I have heard of blowing up are ones that were tuned to the extreme and being drag raced. There are plenty of 3.5 EBs north of 100,000 miles on them that have been regular haulers. Ours has about 80,000 on it and the only issue we have had is a leaking water pump.

My brothers shops numbers for 2018 came out a week or so ago. Since the eco was released, the f150 has made him the most money every year lol. And before that is was the 4.6 v8 f150. I’ll see if I can get a copy.
Like I said, not against it, I’d just need to see it work for a long time before I jumped in.
I’m with Dakota, the future will be interesting to watch, from my 6.2 Raptor!
Or a LS powered centurion if the raptor ever starts acting up. Lmao

I would also imagine he has an absolute butt load of those motors out there and they are working hard in a lot of cases?

Those numbers might also correlate to it being the #1 seller for Ford. I also agree that I would rather the 6.2 Raptor for now. Might be interesting to see the 7.3 in a few years though.....

Not surprised Ford makes him the most money, they are the most common half ton trucks in the country. More trucks equals more trucks getting worked on.

Theyíve been using water cooled exhaust turbines on marine diesel engines for years. I donít think it will a problem. Iím still not a fan on the eco boost motor for many reasons. Itís all about low-end torque.

Not a fan of the ecoboost because its all about low end torque? That's something you don't hear every day.

The 3.5EB makes peak torque at 2250rpm and has a broad flat torque curve. This is a byproduct of tiny twin snails.

Most guys trying to make BIG horsepower say in a V8 application opt for 64mm+ twin turbos and those suck for low end torque

I had 185k on my 3.5 (with a light tune) when I sold it. I was impressed with the power from that motor, but not the fuel economy. That said, I have driven the smaller EB motor and it makes sense it’s going in a jet drive.
