That plate on the transom was put on there when it was still with the border patrol, I really dont think it is needed, my buddy runs a similar hull and we never have water come over the transom...i think its more for peace of mind..

My guess is that they did have water come over the back at one time and freeked out, so they moved the engine forward.
(too much).

cudacat: I've got to do the exact same thing but in reverse right after duck season. the thickness (take off) for the 2.68-1 rotator is 19". I've got to move all mine forward since I'm adding one. Think your right on the nail about someone removing a reduction. And that beer can away from transom, beer can down for distance prop works well. I have a splash gaurd on my Panther, just like the one shown in ur pic. Without it I would be texting this from the bank rather that typing it from home. My first airboat was a cotton mouth with a 12" transom/no splash gaurd. I liked to drown on every stop. Don

Well I pushed the motor stand back a few inches and before I could get it bolted back down I had decided to cut the drivers seat and drivers seat floor out! what the heck I have a few months of bad weather. I started the project last weekend and if I knew it was going to take me 10 hrs to get it out I would not atempted it, but now I'm glad I did. it was way over built and built well but weighted in at 202lbs.. yes that is just the drivers seat stand and floor not the whole seat stand/motor stand. just the box that hold the seats up and floor....... After the long day I sat had a few beers looked at the work I had done. I made a good plan on the new seat stand while drinking a few more beers and what do you know I seem to find a few more projects to do to the boat. I will post some pictures of the rebuilt as it goes this next weekend.


oh yea if anyone need a free seat stand and floor come get it.

Hope you take and share pictures of this project - it would make a great feature story for Marsh Rider and I'd sure like to see them ..

Are you building the new stand out of aluminum or just designing a lighter weight steel stand? I agree with you on being over built..thats the first thing I thought we he had it done....better than being weak though.

Bellyup, it started with the rubber coating on everything. I didn’t like the stuff and in the process of removing it I started looking and thinking of different things I could do to the boat to make it perform better and what better time to do it than now.

Did you and lance have that built? It was strong!!! I had to use a hoist to remove it. Lol.. The stand had 20’ of ¼ “x 3”x3” steal angle and ..1/8” steal floor….

I am going to go with a .125 aluminum floor and a ¾” square tubing for the seat stand. I should have my new seat stand done and in by this weekend. It should be pretty nice. I am going to push the gages between the seats up also so you don’t have to break your neck .

I got the new seat stand built and in. It came out pretty nice. I am going to pull the motor and remove the rigging from the boat now to do a little more welding and get It ready to sand blast and paint. I have weighed everything I have removed from the boat and my grand total is 419 lbs. Right at this moment I am planning to put a aluminum diamond plate floor in three quarters of the boat so the 419lbs I have saved may drop. Here are a few pictures from my project. The first couple are the seat stand I took out of the boat..

Of course as soon as you cut that transom plate off you'll wish you'd have had it on.....At least thats how it goes for me...

He had it built by a local welding shop. Yes, definately strong..lol

Good idea on moving the gauge console up some.

Looking good so far!

I hope not because it’s removed, but your right that’s usually how it works. The plate was 31 lbs I think I can do without.

I would have very little modification to do if I push everything back and I would like the extra room up front if it didn’t hurt the performance.

I would suggest calling Diamondback, they manufactured the hull. Bobby will tell you where the engine and prop swing should be for optimum performance for their hulls. I'm with the rest of these guys, I would move it back, but I would call DB and get their opinion first. JMO

That stand is/was hell for stout.... the only problem is basically it was never relayed to the welder HOW important weight, or lack of weight, is to an airboat. Other than that it was fine.

Looks like you are headed in the right direction.

On the transom... I would not think an AL splash guard could be 31 pounds, but assuming you didnt' trash it.. if it creates an issue, it can be welded back in place.

I'm going to modify my single up top to a double, and I like the idea of the higher instruments.... I just got a motorcylce helmet for cold weather and dang if I can't hardly look down anymore due to the helmet.....

The stand is nice just heavy!!!!
If anyone is interested in the old stand/box come get it. It would make a great start to a quail hunting rig in a UTV or jeep. I can see it on a jeep looking pretty good. I was going to put it in the bed of my mule but its 2” to wide.

Back splash….I was going to leave it on because of the advice I got off SA forum. Everyone thought it would not hurt the performance… I personal have a gut feeling that it does hurt it. It reminds me of a elevator on a plane being locked in the up position. ….. which will push the back of the boat down and the faster you turn your prop the harder it will push the back of the boat down. So I pulled it off.
I also was surprised to how heavy it was when it came off. The aluminum it was made out of was 5/16” to 3/8”. I am just weighing everything with a old bathroom scale but it seem pretty close.

I have been researching the aluminum diamond plate floor. It weighs 1.746 per square foot for .125 think

Do you guys think .125 is too thin for flooring? I am thinking (2) 48x8 sheets should do everything Thanks Andy....

Lots of nice work there - should be a much different boat when it's finished. You have a lot of T Bars in your hull - don't worry about your diamondplate floor thickness - it won't take much with all those T bars. Are you planning to add a couple of hull jack stiffeners?

To tell you the truth I don’t know what hull jack stiffeners are? I am not sure the jacks do much in my boat… my boat bottom is 3/8” and the poly is ½” and with all the t bars. I never feel any flex.

I have a question??????? I don’t understand why in the first picture of the fuel tank there is a 3/8” plate bolted under the fuel tank. You can see the plate in the picture. It does not touch the bottom of the fuel tank nor support it. The only reason I can see it being there is to protect the underside of the tank from anything rubbing on it??????? by boat can lose another 23lbs if it’s not needed.

Pretty sure the floor in mine is 125 also... I don't have quite as many stringers and its fine. I"ll measure it some night when I remember.

Looking good! And I don't have a clue about that plate... I'd say there would be NO need for it at all... if protecting the bottom from the stringers, a couple of extra cross members would do the same at much less weight.

1/2" poly? that stuff IS heavy. Whoever spec'ed that boat origionally must have planned for some very extreme operaions - usual thickness for poly is 1/4" or 5/16" - 3/8" for extreme applications. Can think of no need for fuel tank protection across the T bars. Everything you are doing should really help your boat's performance - Thank You for keeping us all updated ..
