Pretty interesting choice of power.

Imagine if it were installed in a worthwhile boat:)
Lightning headers???

What ya guys think, engine, headers, outdrive, custom fabrication, odds and ends, would this setup be worth it?

+1

What is the exhaust?

35k?

I dont think it was about "this" boat. Read the article, it is about using the LSA in a boat with exhaust below the waterline & prove it can be done with an LSA. Use whatever headers you want. They were on the cheap trying to make an LSA run in a marine environment.

The question is, will it live!

Not a lot of Fab work anymore we have a kit that offers most of the conversion products required

I think a LSA is 16-17K at the dealer, drive, gimbal and such you'd be in the upper 20's but at 556hp and probably 150-200 pounds lighter then a big block it might not be a bad way to go...... if it would live in the marine app.

The lsa is available as a turn key marine package, and has been for several years. The mainstream offshore world is way behind the times on the LS platform. A closed cooled marine LSA is under 18k with a 2 year warranty. We've installed and serviced lot's of them, they make great power and are incredibly smooth. As long as you run premium fuel they seem to hold up very well. The biggest drawback is, you can make the same, or more, power on 87 octane with a 502..

Have they not been running these engines in wakeboard boats for years?

Both PCM and Indmar have the LSA motor set up for marine use now for the last 3 years min. PCM uses CMI headers and Indmar makes their own in house version for headers. I tried to have them make headers for me and no dice.

Looked at the video the boat will break before that motor ever does. What a hunk of junk boat as the motor is worth 20 times what that boat is worth.

Forgot Panther Marine and Marine Power also have marine LSA 6.2's along with GM for at least the last 3 years.

you have any idea how much a fishing boat makes in a year? you like seafood?

Nautique offers a supercharged version of something or another...

The long block isn't that bad, the computer is like 1k extra. There is also the mast motors also.

cmi makes headers for the ls..

I think those are cmi

They specifically say the boat is junk. They are trying to make a point that "it can be done".

I have had LS power for close to 7 years it's a no brainier I'm living proof lol

GM has the 6.2 marinized

Great platform- Seven outbards use one of these engines.

Wannabe

other then closed cooling some header's and bellhousing what else has to be done to put them in a boat ?

well heck, why not offer all of the conversion products required?? seems like you should make a complete kit, so guy can buy a low mileage engine out of a wreck and marinize it with your kit and go boating... logical huh?

mast has some nice stuff, but i think they are too pricey for what you get...

how high do you rev it, what kind of hp does it make?

what outboard has one of these engines under it's cowl? i dont believe it? you must mean i/o

this is mine , I run it up to 6500 very strong running engine ,my next project will have two ls engine in for sure !

I run the mast ecu ,not the easiest program but when I started there was not much headers are lightning and the cloosed cooling is from Pcm ,bell housing and coupler is just bolt on merc.

Could you send some pricing of the ls kit s you have to [email protected] ?

thx

Mast uses a ECM from E controls in San Antonio Texas so does Volvo Penta and so does Indmar with all their LS and LSA engines. FYI. I talked to Horace Mast in person about his business selling LS and LSA engines for the marine end at this point in time he is way to busy on the auto side.

He did advertise the one marine LS engine in a few boat magazines for the last 2 years but he does not have any in stock to sell. The marine side so small of a sale to even worry about for his business. Now if you wanted to get something built for the marine end that is a different story but you would have to wait for awhile for completion.

Seven Marine has had the Outboard LSA caddy engine out for 3 years now. It has CMI headers, MEFI 6 controller and uses Latham hydraulic steering for the jist of it.

This cannot be done! It will blow up because it does not have the name "Marine" on it! lol

I really don't know why people think a marine engine is built any better than a race car engine.

If you got a check book and are brave, try some Sprint car 410 to 430 pushing 980 hp with no turbo or blower. Of course they will also turn 9500 rpm all day under load.

I can set you right up!

So can Earl Gaerte and Shaver, but these mills awesome as they are don't work in boats with outdrives.

Its not that a "marine" setup is "better" they are just set up to make power differently and work with the limitations of the environment-

Stuff like a sub 900RPM idle another being an RPM limit of about 6K, another being a wet exhaust - another being 1 gear (with no clutch) from idle to top speed.
Sprint car engines have none of these limitations.

Hey Dave UD - I promise I am not following you up here. LOL

Dart is getting heavly into the LS side of the coin - they market it as LS Next

also Mast is huge with LS stuff all across the world. IMO has the biggest name in the LS - LSA industry. Anyways I run into them once or twice a year and pick their brains. Mast is in my neck of the woods - Texas.

All good Bup!

UD

I haven't followed what is the difference from a LS ver LSA?

The LSA is an iron block 6.2 liter with a blower that makes 556 hp. GM puts it in the CTS-V. "LS" refers to the newest generation of small block chevys. Could be anything from a 4.8 liter truck engine to a 7.0 liter found in the Z06

http://en.wikipedia.org/wiki/General_Motors_LS_engine

The LSA is an Aluminum block.... http://www.gmpowertrain.com/Librarie...rine.sflb.ashx

LS is the aluminum block series from the LS1 to LS9 which are found in performance cars / Cadillacs typically.

The newest series of engines are the Gen V series found in the 2014 trucks and the C7 Vettes- Direct injection platform..... http://www.caranddriver.com/news/gen...c7-engine-news


Cool stuff on the horizon !!!!

In the marine end you will see changes coming with the GM engines. Mercruiser still will be the only Marine engine manu not doing a LS or LSX or LSA based engine. All Marine ECM's will be standardized like the OBD 2 was for the auto end as they did many many years ago. Date for the marine standardization is 2017 year models.

Direct injection is here on the auto side and the marine end will be seeing it real soon as the V-6 / 4. 3 L Marine direct injection engine is already here by GM. Also V V T is here on the marine side and will be on all engines to come down the road. Outboards will have cat systems like the inboards &/ I/O's. Outboard manu's have been testing the cat systems now for over 3 years straight but still can make the system full proof for any length of time. Also the 6.2 Ford Raptor engine is already here on the marine side and being offered in a few months thru Indmar. Indmar really likes that motor and have run it thru its paces. They said the torque is unreal for the wakeboat crowd.

A couple years ago Mercruiser did announce to its dealers that they were coming out with a GM LS engine to replace the 8.1 L and or the 6.2 L anyways they dropped the program and said to me in person it would last nor have the reliability that they already have. Hence the newer 8.2 L with cat system and kept the 6.2 L with cat system. All marine I/O's & inboards under 500 hp have to have a cat system / 4 - O2 sensors since 2010 and since 2008 in California.

Volvo Penta does not have any gas power Big Blocks for the past 2 yers as their whole line up is going LS. They now offer 3 versions of the same 6.0 LS GM base - 350 hp and a 380 hp and a 430 hp all the same 6.0 L LS GM engine just tuned differently. They use aluminum exhaust manifolds with cat installed. FYI

Is anyone going with the 7.0 version? Seems a 7.0 with SC could be a nice light 570-600 HP motor.

I don't think that block (if you are speaking of the LS7, C6 ZO6) is really designed for FI. It is a lightweight design for a lightweight track car. Not sure it would handle FI load for extended periods of time. I am sure someone here has firsthand experience with that one?.....

About $8k for a new LSA shopping around. Sounds like a good deal for 556 HP
