Beautiful setup! They build a nice rig, just heavy.

Why wouldnt you want an LS? amazing power to weight ratio and very reliable if built well.

A very good friend of mine is coming into Ft Myers friday 6/12 from Utah and he asked me if I knew anyone that might be willing to take him out for a little ride. He is an experienced airboater and has ridden with me hundreds of times so hes not a newby. He is willing to pay for all gas / beverages ...

I run one on my carbd LS2 waterthunder. I also run a prefilter on it. I don't run any debri or dirt so Im not worried about its filtering capabilities but I do like to think that it breathes easier.

agreed with digging.

If any of you fine folks happen to find yourselves in the Northern Utah (just north of Salt Lake City) during October, November, December and half way through January consider this an open invite to get in contact with me and I would love to show you why I love airboating and hunting in Utah. If you...

I disagree on the recycled stuff. I know numerous people running it that have had the same or better luck with that than the virgin stuff. I recently replaced my virgin blue iron with black regrind (repro) and I can tell just by handling it that it is more dense and higher quality than the stuff I t...

the widest prop you can find will give you the best low end thrust IMO.

Any new developments with this issue?

To push on dry ground, I would highly suggest getting a reduction. I think you can find old Kway belt reductions for less than 2K on occasion.

What fuel delivery system are you running? obviously not a self learning one if it is not performing at higher rpms?

Agreed with all the above posts. Either something is wrong in the cam or possibly something is hurt in the motor. It should spin that sucker a lot harder than what it is. I would get some live data from the motor if you can..

I prefer my dickies pants. Reasonably priced and durable as hell. I'll look at this rural king stuff though! thanks for the info.

I think I'm going to order the Fitech kit for my LS2 soon. Just debating which kit to order. Do you guys run the "Go EFI" kit or the "Ultimate" kit with a new intake manifold?

I have a 16x8 Utah style hull with a Waterthunder 550hp motor on it and it does surprisingly well. I go pretty much anywhere I want within reason. I don't think youll be running dry with 2-4 guys in a 16x8 with only 450.. but it might work well for what you want to do with it. just depends on your n...

Can you wiggle your prop by hand, see if it has any side to side or wiggle in it? Maybe your prop is out of balance? I would check all the bolts on your prop first. Did you lock tite all the bolts on the flex plate and drive plate?

very cool! What type of speeds do you get with those things? I'm assuming they don't carry a load as well as an airboat do they?

I read some thrust testing studies years ago that said the Sensenich R blade was the most efficient prop at producing thrust. Plus, I like the design of the blade a little better than other manufactures designs. I would own a whirlwind prop in a heartbeat also just because of their customer service ...

I had that exact same thing happen to me this last November. Really sucked. especially because it took Century 3 weeks to get me the parts I needed. and only after numerous phone calls..

I have a 550hp Waterthunder Ls2 on my 16x8 Utah style airboat and it does very well. I run a CH3 2.3 and 3 blade R series. I could run it a little higher rpm than I do, but I keep it around 5K max to keep my cruise rpm down and it does everything I could want.

I have an LS motor on my Utah style airboat and it is incredible. I personally think they are the best motors available for airboating considering the power to weight ratio. But, like Rich says, its hard to beat a good 383 stroker motor also.

How high do you want to rev your motor to get maximum rpm out of your prop? With that prop, motor and hull combo I would go with the 2.88 and let it rev higher, if the valve train can handle it.

Agreed? Having to chase him down for my box was great. You must of had a better experience Yeah, the guy was a wealth of information and very pleasant to talk with. I never had any business dealings with him so I cant speak to that issue but he was a dang good guy and always willing to help (me bei...

Anyone else have any issues with the "blue iron" poly wearing out WAY to fast? My boats poly was done about 10 years ago, which seems like I got a fair amount of life out of it, until you realize that we only use our airboats during duck season (October, Novermber, December and half way through Janu...

When everything freezes up around here, we have a pull off pole we hook up to and drag it off our trailers onto the ice and snow. Then we can slide right out to the open water of the great salt lake. Getting back on the trailer can be challenging but we also built a ramp on dry land, as long as it i...
