The reeds and brush are about 12 ft tall and the bottom was dry. I made it in 100 yards no problem but when I stopped to take a look around I couldn't get it moving again Duckman, This past weekend I got into some 12 foot high stuff myself, the bushes started turning into trees. Off to my right I s...

This thread and build #2 ain't dead by a long shot, making plans to rebuild the red boat for sure. Got a set of rudders ready to go. Full airfoil, 4' x 4'. https://southernairboat.com/wp/wp-content/uploads/rtMedia/users/2619/2020/08/Rudders-1.jpg?1597280480 https://southernairboat.com/wp/wp-content/...

I just double checked, your buddies are correct, I was wrong, they are not interchangeable. The 2 bolt pattern is rotated about 90 degrees between the two. Here is the bolt pattern on an angle valve. https://southernairboat.com/wp/wp-content/uploads/rtMedia/users/2619/2020/08/AV-Header.jpg?159715642...

Headers are interchangeable between SV and AV 540 motors.

Don't go bad mouthin my help, they work for juice boxes.

Idiot here. We use a mix of shotgun, pistol, dogs and knife for hogs, it's a hell of a good time.

I am the same as Lariat, I have tried the Q and Whisper tip on SV and AV 540's, I settled on NGQ for both for best ground push.

Most width figures are given at the top of the transom, which basically defines the maximum prop diameter. Width at the bottom is what the boat rides on and is a function of hull form. Wider, with less taper gives a wider bottom that will run better in deep water, grass etc. A wider bottom will jump...

Call Port Consolidated before going, They run out on a regular basis.

I think this quote basically sums it up. All airboat headers are made to be affordable. They are not designed to make power. Thanks, Chuck I have one boat with shorty headers and 2.5" flex into Magnaflows, the other is the 3" shorty with built in resonator blasting onto the prop. The resonator setup...

I forgot to mention, check the tank vent, them dirt dobbers can clog up a vent and burn up both the electric and mechanical in a 5 minute span. Ask me how I know...

Bamaso, I am on-board with Kwan on the ground to starter cable, you will notice the difference. That said, if she won't turn over now, the ground cable is not all that needs sorting. I have new everything in the start circuit, Norman Clay starter, Optima Blue top and #1 AWG ground to starter. I can ...

Seven is correct that the narrow deck, straight valve 540 is the lightest and most robust variation of the 540's, it is a very reliable engine. The less desired comment is based on pricing, Narrow Deck cylinders do get a bit of a premium these days. I run a narrow deck O=540 pushing a 14 foot rivete...

Have you replaced the Racor? Most electric pumps also have a screen on the suction side that should be checked/cleaned.

The mechanical has check valves that might be leaking due to corrosion or debris, the diaphragm is either good or bad, no real in between.

On to the actual riveting. Rivet hammer, 3X (4X would be better for this job, but 3X is more versatile). Round head attachments and buck bars. https://southernairboat.com/wp/wp-content/uploads/rtMedia/users/2619/2020/07/IMG_3522-600x800.jpg?1596326675 https://southernairboat.com/wp/wp-content/upload...

I'm looking at purchasing 0540 straight valve narrow deck do I need to be concerned about all those abbreviations after the 0540. Any good advice Wikipedia is your friend here for all the model codes. But keep this in mind, with airboat engines there is NO guarantee that the model code on the oil p...

I'm not that familiar with the Turbo's either, but I agree with Diggin on most of his post except for this. The point to all of this is that if the engine is rated at, say, 315 hp, it will still make that power without the turbocharger since you will be operating the engine at or near sea level. I t...

I guess I should have mentioned, I met FishSticker and many others through SA, So thanks for keeping er running Rick. Whats the scoop on stickers build? He has not posted an update recently? Kwan, a cognition test for you, see if you can pick the word that doesn't belong: Airboat AV Gas Magnetos (2)...

With the exception of a few hours here & there this old website has been online continuously for about 18 years till this week. Down (3) days...that was pretty rough on me too. Rick Thanks for the hard work putting humpty dumpty back together again. But I'm starting to think that you should just do...

With the bushings worn out I think it could go well past the original timing. Also check the end play of the drive gear. The shims are probably worn out allowing the shaft/gear to push up, which changes the timing further (more advance I think??).

Yes, the anode would need to be on the outside, in contact with water. DO NOT use magnesium anodes in salt water as it can make aluminum brittle due to excessive current. Zinc is correct for salt water and would be my go to for all waters for simplicity. I don't run any anodes, they would need to be...

It was #3 cylinder. #1 had just started to do the the same. I run a Ford 2100 2bbl. I dont know jet sizes. But I have since found that my distributor was slap wore out. The bushings between the pin and weights was completely gone (both sides) and I believe from the markings under the rotor, im now ...

There are a lot of options for a 5-7 PSI prime pump. But on an injected engine it is best to use a prime pump that makes sufficient pressure to run on if the mechanical pump fails. I'm running Continental Injection on a Lycoming 540, but only a low pressure prime pump at the moment, upgrading the el...

There are basically 2 different rivet styles, and several materials. Primary rivet styles are Flat Head (AN426) and Round or Button Head (AN470). This picture shows a 3/16" diameter Flat Head and a 5/32" Button Head. https://southernairboat.com/wp/wp-content/uploads/rtMedia/users/2619/2020/07/IMG_35...

Great info! Thanks for sharing. You beat me to the jokes about the screws not running well. Thanks lariat, I can make a pun... I hope this helps folks understand the processes. So forming involved some marking, some hammering and use of the rivet hammer and buck, on and off the boat. On a new build...
