WHY :?: sorry I couldn't help it :lol: :lol:


all I can see and assume is a new stand, engine of course and you have to add a radiator
 
Why :joker: ? Sorry, I couldn't help it either.

I'd call Waterthunder and order the engine and get cchardt to build the rigging.

What hull do you have?

It may be better to sell your boat and find a car motor boat. You'll also need a reduction unit and new prop.
 
well i was thinking it would be cheaper to build a car motor than to rebuild an aircraft motor iv been doing some research but i cant find any prices on that kind of stuff. im looking for my first boat and im trying to figure out what i want to go with.
 
10-4 It's alot of choices and you'll get alot of different opinions.

I suggest you attend one of our rides and see all the different combinations. You can most likely get a few rides and depending on your use and $ to spend have a better idea on where to start.
 
yea i was really looking for an aluminum hull with a 350 but im having a hard time finding one that isnt to high in price its my first boat so im trying not to spend to much . that s why i was wondering about switching the motors out after running that airplane motor till it brakes down but are the aircrafts hard to work on.
 
in my opinion it is always harder and more expensive to change a boat form it's original design you are better building or buying the type you want . if you don't like the AC motor ( I have to ask what is wrong with you :lol: sorry) the suggestion to sell your boat and by a car motorboat would be the cheapest an best way
 
i like the AC motors but i didnt know how expensive they were to work on on how expensive fuel for it would be.
 
At the risk of starting another arguement.....

It's a good thing car motor parts are cheap, because you'll be spending lots of time working on them!!! WHHOOOO!!!! HAAAAH!!!! :p

Seriously though, what are you looking to do with your boat ??? Some applications lean more toward one motor over the other. I don't know your level of engine building skills...you may be a whiz with chevy's or caddies in which case it would be a no brainer, but don't be intimidated by aircraft if you aren't good at turning wrenches...I don't know the difference 'tween a crescent and and a prybar.....

The parts might be more expensive..depends on the part I guess...but I'd put more emphasis on what you expect your boat to do over what is the cheapest way to get started....

Hang around and keep asking questions before you put down any money....

Oh, and don't forget the most important thing about aircraft engines...Chicks Dig 'Em!!!!!!!

do you weld it isnt that hard ac motors are pretty easy what motor you got if you cant do the work sell the motor and youll sould have anuff to got your car stuff
 
i plan to use the boat for duck hunting so i will want to get to the hard to get to spots. is the fuel for the AC motors expensive and what kind of fuel consumption do the have.

Well, the price of fuel really seems to depend on where you're getting it from. If you have to get it from airports it tends to be pricey...I think it's up around or over $4.00 a gallon in many places now. In Central Florida, some small gas stations carry it at a much cheaper price ($3.50) or so. Either way it ain't cheap. If you've got a good fuel filter system, talk with your local airport and try and get into their fuel sump avgas..that's the stuff that they take out of the tank periodically to test and whatnot and they can't resell it at full cost.......

Or, depending on what motor you have, you may be able run high test pump gas. I had an O470 that ran great on 93 and all the literature I found on that specific model I had said it was designed to run 91 or maybe 93 I don't recall right off te top of my head.....

As for consumption...that's harder for me to judge as a whole. It seems no two motors ever have the same....I've seen some that are dogs and others that seem to make fuel. I guess it depends on how heavy your foot is. I've got a twenty gallon tank and I carry a 5 gallon jug of insurance and I haven't been stranded yet. But I don't do any 60 mile runs that often either...,..

How big is your hull???How many people and how much gear do you plan on hauling around ???

Well I have both Car boat and an Aircraft boat and the Aircraft is clearly more expensive the parts and the fuel are considerably more and you can get parts for a car motor any where you have to hunt for AC parts and usually pay dearly for them but AC motors are reliable but so is a car motor and they will hall a bigger load for a lot less money plus most of your AC motors at least the 6 cylinder ones are a lot more ci so they burn more fuel plus they are cooled by the fuel besides air so they run a richer mixture which also means a bigger fuel consumption and the price per gallon is almost twice as pump gas but having an Ac motor is a lot like owning a Harley they are a classic and they do sound cool and preform well but like a Harley there technology is very old and Airboaters seem to be the only one's that do things to modernize them.
 
I would get the aircraft motor and boat and then run it until the motor breaks down like you wrote. You may be surprised how long it takes to break the motor. From the prices I've seen for Car motors, gear boxes and propellers, it looks like it is a lot cheaper to overhaul an aircraft motor. There are a few folks that rebuilt aircraft engines that do it for a very good price.

If you are set on a car motor then I would get a car motor boat right off. The work in changing them is usually more effort than it is worth. Airboat trader has each style in about any price range you want. Just my opinion but I think aircraft engines are a lot easier to work on than car motors.

I know there was a reason I liked having a AC motor :lol:

I run 93 octane in mine and it does fine , your fuel consumption would depend on lots of things like the hull design and weight, load, rpm's, prop etc..
I was talking with a friend the other day and he said something that makes real good sense for this discussion.
" if you have a cyl go bad on a AC motor you just pull that one cyl off when it is still on the boat BUT car motor you have to pull the whole motor out of the boat and break it down"
 
some chicks might dig AC motors but those are the ones that have not rode in a good running Car motor boat my Girlfriend works on Warbirds for a living P51,P47,P38,F4U4 and is the crewchief on a B-17 and is the Pit boss at the Reno Air races and she was so impressed with my Thunder powered boat that she no longer wants to buy a Harley for her Birthday,she now wants an Airboat that just broke my heart :D
 
drake, it really depends on what size boat you're running and what you HAVE to run through. how many people are you hauling? how far are you running? a lot of variables there. honestly, when i build another boat its gonna be a car engine. i have a lycoming now that i love. i can carry 4 guys and 2 dogs with no problem. but, simply put, a strong car engine thats set up right will run where most A/C engines won't. however, a good A/C engine will last for 100 years!!! you need to contact Faron with American Airboats over in Orange and he can offer you some good advice...

You say aircraft is clearly more expensive. Did you know a replacement cylinder head for your motor is $1524.00 and over $3000.00 for the pair. I not sure how plentiful as for the supplies of over hauled heads for that motor or how much if you even get one over hauled. But you can get an aircraft cylinder that is overhauled as cheap as $200.00. As for fuel consumption I have a supercharge 0540 and my Dad has a zz4 on a lighter hull and we go to the exact same place at the same time yet he burns 2 to 3 more gallons then I do. That is because I don't have to run as hard :D But if I had my choice I would make my next boat a LS-2. I just don't think any motor is the wrong motor. They all have their weak and strong points.
