Dang it ya'll I try so hard to stay out of this stuff. LOL ok here goes.

I have an airboat motor on my new boat. It wouldn't work for crap in an automotive application. It isn't a generator motor, and it isn't an airplane motor ... It was especially built for an airboat. a true a/c motor is meant to be run at a constant rpm and never was designed for the up and down throttle applications in an airboat. The generator motors were designed to be run at a constant rpm as well. An automotive engine was designed to be used in a car application where the loads get less once the car is moving and the rpms were meant to be decreased in proportion.

An airboat motor is designed to generate hp & tq across a wide band and is designed to never free wheel and the load is constant. There is no comparing it to a car motor except for its appearance if you can get past looking at that 82" super wide q series sensenitch prop turning 1650 rpms a wide open throttle. It has eight cylinders in a v configuration and it has a radiator and a carb. Just like a car motor but that is where the similarity ends it is and was designed for airboat use only. It is AN AIRBOAT ENGINE period.

So when that eight cylinder ground power motor boat was stuck and I almost had a heart attack pullin on it I told that fella screw this I am gonna get my boat and pull you back to the water he just laughed but he aint laughin now. When I had 5 adults, 30 gallons of fuel all my normal gear which is considerable if you aint ever checked my boat out and 150 lbs of frogs and climbed up hill turning 90 degree corners between trees and then loaded it on the trailer with all still on board and the uphill part was probably a 1/8 of a mile long and at least 40 to 50 feet rise. That stuff takes an airboat motor, when I had four on my boat and stopped in the black mud and picked up four more and a large dog and had coolers of ice and drinks and one of those pickups weighed over 325 lbs easy and drove through the woods around corners you had to stop and spin to make it around and placed them back where they came from that takes an airboat motor.

Now thats just my opinion but I don't have a car motor but it does resemble one on the outside. LOL
Don't waste your time ... it is the only thing you can't get more of
.. if it accidentally looks like I gave advice please ignore it .. and notify me immediately

I agree with you I just had a WaterThunder Airboat motor put in my boat it one of his LS6's and I have been amazed on how much more power it has over the ZZ4 that I had and it is 200 lbs lighter and is a lt better on fuel to and the best part like you said it was built for an Airboat by an expert Airboater WaterThunder and my oppinion is that these type motors are going to change all the rules about Airboat power plants

I suspect a lot of folks, not everyone, but a lot of folks run what they have as an interim boat until they can afford what they want. Most likely they have what they have because they could afford THAT deal right then. In some cases that may mean running one or the other engine while saving for the opposite.

Not everyone can just open their check book and write a check for what they want right off the bat.

Just thinking out loud here. :)

OK, but it might also have something to do with the boat they first learned to drive, a boat their Daddy had, or the first car they ever loved ... that '68 Camaro. I think Fatboy is on to something here.

Can't find any argument there. I still look at little VWs fondly when I blast by them in my big ole truck. I learned to drive in an imported one way back when, still like em. I'd say same for lots a boaters. Makes sense to me anyway.

I voted for car motor because that's what I have. I have been building my boat for the past 3 months and am still not finished. I am building a direct drive 350 because that's what I can afford because i'm only 18. The engine is a 98 Vortec that was given to me. I haave totally redone it and converted it over to carb. I will be finished with it in a few weeks. I would love to have an aircraft motor, but this is all I can afford right now. I've enjoyed the project so much and can't wait till the first day I get to take her to the lake.

Got that right Olf.

I don't remember ever meeting an airboater who eventually was'nt saying: " I wanna get this, or I wanna do that to my airboat"
Even ones who were riding really killer rigs.

It never ends.

Nor will people argueing about A/C vs Automotive. That's just another part of it, and I think it's funny!

As long as your out there airboating, that's what it's really all about.

Rock on with it Robby.

I think that is cool that such a young man is out there building his own Airboat I sure if he ever needs help with it there will be plenty of folks on this site to offer him some help.

12' Cottonmouth with 4cyl Lyc..
0-320 (1957, Waterthunder) New 160hp pistons $45 each, ring sets $36 each, cyl gskt sets $8 each, cyl overhaul w/ new exh valves $125 each
and carb overhaul $170. Just a top end overhaul. A little over $1,000.
Now if it needed a crank or replacement cyl then it jumps right on up there.
This is what I can afford. A $5,000 boat verses one for $15,000.

I'll stick with A/C.
