Hi Kevin, it is an Alumacraft 1436, which means that it is 14 ft long, 36 in wide at the floor, and approx 54 in at the top of the side.

Eli Anton Hi Eli, the boat will not power over dry marsh. I have driven in 1” of water over sand bars/mud and over reed thick over shallows. At speed I have slid over dry sand bars within the Red river. The engine puts out 48hp. You would need +120 hp to push you over dry grass.

@@nwsw5764 thanks for the reply!

So it won't go over just dry grass that's why I wanted to do it have water back yard and grass

No I have not. The bottom of the jon is very thin and flexes too much. Better option maybe would be to put acrylic plastic sheets to strengthen the bottom but The added weight and cost doesn’t justify the work. My intent was to make an inexpensive (affordable) airboat that works well over the swamp and shallow water which it does. Cost to build with off the shelf parts just under $9k. Which cruises at 18 all day at about 75% power. Try buying a comparable one for that price. This boat is fun and affordable.

Hi David, For the engine size, yes. The engine will push the hull to a cruise of 18-19?mph. WOT is 20-21. Blessings, Norm

Less then 1 inch

Hi John, I purchased everything off the shelf. The boat from Academy at $800. The trailer from Academy for $600. The engine from Performance 670 for $2,800. The fan cage, controls, rudders, propeller, reduction drive for $3,800. Misc parts for $300. Labor mine. Total cost approximately $8,300. I could have saved thousands by making the fan cage and controls. But I wanted to save time so I purchased everything off the shelf. With a full load of two people plus misc supplies it runs 22mph. With just myself it will run 30 mph. It goes through reeds, over virtually no water with no issues. I have not run it over mud so that I don’t know. But for basic air boating it is a blast.

Thanks for the reply they didn't notify me of it

The engine and exhaust are stock. Had a Yamaha water silence (muffler)

Removed the water muffler and now it is exhausted directly thru the transom using exhaust scupper valve.

Oops, that is the 120 hp jet jon. The 48 hp Predator uses a stock Predator muffler with an extra exhaust port added.

Cost about $8500 for all the components, boat, prop, prop reduction drive, prop cage, rudders, engine, controls, seats, wiring, etc. Bought almost all parts off the shelf at retail prices.

Hi Russ, That would be taking the build to another level. This is done in aviation to reduce drag and improve thrust. But it comes a huge cost and requires exact engineering to insure that the correct dihedral, pitch, angle, length, surface smoothness, etc., of the cowling to reduce drag and improve thrust. This is way beyond what I can engineer in my garage or afford. I build this just for fun and it is quite fun.

I'm putting at scat hovercraft motor setup on a 10 Jon boat and wasn't for sure if I wanted to use the factory shroud

Hey Russ, contact Ben King at Lonestar Hovercraft at info@lonestarhovercraft.com (817) 944-1957 www.lonestarhovercraft.com Ben is a PhD in physics who has a passion for air powered ground craft. He can be a valuable resource to help guide you in your pursuit. Blessings, Norm

@@nwsw5764 norm what pitch did you set your blades in conjunction with transem

@@olruss4039 I bought the propellor from Ben at Lonestar hovercraft. Please contact him for any details about the prop or reduction gear.

The engine was modified by Performance 670. It is definitely not stock. So far no issues. You can use the Vanguard 40 hp marine engine for a few more $$$$ if you don’t trust the Predator 670.
