No they don't, that only occurs when you plot Torque in Ft-lbf against Hp on the same scale. Plot them on different scales or try metric units and you can make them cross where ever you want. 5252 is meaningless. Oh but they do, and of course on the same scale. Ft lbs vs hp on the x vs RPM on the y...

Does anybody know the specs on the cam? :stirpot: :stirpot: I think everybody knows the answer to that. So why do you think it was a radical cam? What RPM did it idle at? Very lopey idle is the only indication. I have no idea what the specs are. Did not pay much attention to the idle speed but I di...

No sir just a regular Performer. Idle-5500 power range. Not sure it would act right after being on a Ford motor! Lol

Looks like a great place to ride. How far up the river are you allowed to ride?

Hi all.....been a while sense ive been on this board. I also had Dave build me a DD LS. The motor is a LS3 block EFI holley system 430 CI, Chevrolet cnc heads. Dave (Waterthunder) has a thrust tester, it will measure thrust output.....it makes 1100 pounds + At 3600 with the Alpha 66 Most straight v...

I'm not sure what RPM he has it pitched to. I just know that by the time you hit 2,500, you don't want to be looking down anymore.

He's running a cut down (66") three blade Sabre.

My bad. It's a cut down Alpha. Not Sabre.

He has a machined bracket that fits behind the flywheel that I believe has a thrust bearing and acts as a motormount as well.

It may not be my place to talk about this boat as it is not mine but I did get to take it for a ride yesterday and OMG. I've never seen a boat with a more appropriate name. This boat truly is a game changer. It's an 11 foot Benny Webb with a direct drive Waterthunder LS3. The owner of the boat said ...

After watching Pipedog's video and looking at Google Earth, I'm wondering if you can run all the way from Lake Istokpoga to Lake Arbuckle on the creek. Has anybody done it before? Perhaps camp along the creek overnight? Looks like it would be a great time. Talking to Pipedog, his group turned around...

we put in on 41 and went all the way to the swimming hole, there was no rub on plane getting in or out of the canal. I started to rain some more as we left yesterday so I dare say there should be plenty of water come next weekend even for the CM crowd lol C'mon, Ish. That's not a challenge, is it? ...

While I certainly wouldn't discount the knowledge of most people on this site, you will never find more knowledge than the folks at Sensenich and Whirlwind. They've seen every combination imaginable and are an enormous free resource. Since you already have one, I would start with Darren at Sensenich.

look up ffjpowell on here. He and several of his buddies all ride up that way. Awesome people!

Birddog247 on this site runs an old 350 that he pulled from a van, 2:1 gearbox, 2 blade R, on an aluminum hull, and I've yet to see him sruggle on the hill with 2-3 people. The belt box in question weighs more than his gear box, but the combo operates the same. Set-up would dictate how it performs,...

Would not have wanted my fat pig of a boat up in there!! I don't care how much HP my engine is making. If your boat got stuck, I'm not going!! LOL

I would think any auto mechanic should be able to do it for you. It's fairly simple to change the oil, oil filter and change out the oil in the gearbox. I suggest if you are on FB, go to the Southern Airboat FB page. Far more likely to get someone's local attention. Lots of airboaters on this coast ...

Swamp is correct. Blackwater's done quite a bit of experimentation. He tried 2.38, went to 2.68 then 2.55, which is where he stayed. Last time I saw him, he was still running 4 Superwides at 84 inches. Don't recall his max rpm but I think I remember it was around 5,200. His boat was 18 feet and woul...

Good deal. Fished the SKA for 5 yrs. Yellowfin all the way. Fished a 34 YF & 36 invincible. No comparison even btw those 2. Wish I knew u were sorta in the market. Buddy just sold his 36 YF with trip 300. Sent from my [device_name] using [url]Southern Airboat mobile app powered by Tapatalk[/url...

Diggin. Look at a yellowfin for that price. Way better ride. My .02 Sent from my [device_name] using [url]Southern Airboat mobile app powered by Tapatalk[/url] Yeah, J, that's the direction I'm going. I've been looking at Contender, Jupiter, Regulator, Scout and Yellowfin for a while. That's why I ...

Seen a kid the other day at a marina filling up his new quads on his new contender...HS graduation present! 300k boat I can assure you a new Contender with quad anything is going to be well north of $300K. I'm looking at 32 foot used Contenders (3 - 4 years old) with twin 350s and they're going for...

Can someone show me the numbers on how anyone can spend 70k building an airboat. Specs can be a production welded poly open hull of 14ft - $7,000 LS motor of course since they are the new rage. - $15,000 Gearbox - $3,800 3 Blade Props - $3,000 Stainless Rigging - $2,500 Paint or Powder coat - $1,50...

Rumor has it there's a Benny with a DD WT 427 hitting the water soon. Supposedly made over 1,100 lbs of thrust on the test stand. JS

And I'm out there every weekend. My camp is only 4 miles from the landing.

Don't do it if you value the finish of your truck. Between the asshole kids doing donuts at night and the buzzards ripping your wipers and molding off the truck in the morning, not to mention the sh*t, sand and claw marks, your truck is going to get tore up. That being said, I've never had my truck ...

Look to see if all injectors are firing. Get yourself a set of noid lights and make sure all the injectors are getting the signal to fire. It's a real simple test and the kit is under $40 on the high side. Make sure you're getting spark on all cylinders as well. I've had both issues with my LS; bad ...
