Riley,

Personally I like the road sign rudders. And I like that you have NOT painted over them. That way, they keep their redneck authenticity. :lol:

As far as I know, it's not illegal anywhere to possess old road signs, or of any requirement to be able to show proof of where they came from. ( I may be wrong on that, but I don't think so. )

Recycling them for rudder duty is just the "green" thing to do. :toothy7:

Wish I could get it right every single time guys, but I don't think that's in me anymore. When I was a teenager I really did have all the answers an by the time I HAD teenagers, I didn't have ANY answers. I'm slowly clawing my way back but not sure I got enough time left to get back to those teen years LOL !

Never worry about saying something if ya see me getting it wrong. I know where I stand and I know I'm really not all that perfect, so nothing wrong with pointing out anything to me. Once I saw the comments I went back and re read my post and damn I was actually embarassed for Riley. I doubt that I would have been as graceful and accepting of my apology had it been reversed. I guess when my head is in one room and my fingers and kybd are in the other, I need to wait til they are both in the same place LOL ! All y'all is top notch far as I'm concerned!

so I got it out on some water today. I mostly putted around getting the feel for it. I was thinking about decking over the back 1/3 and I definatly will. next time I'll build the sides taller. these are 9.5 inches and I think about 12-14 would be good. I think it will plane out but... when I was going for it I hit a rock and cracked the plywood bottom :banghead: now I've got to figure out how to be rock proof and light... hmm.... sheet metal? fiberglass? poly? I'll figure something out.

some more pics. you can see the crack in the hull in the last pic. it's right in the middle between the engine and the seat, look right below the valve cover. i'm thinking i'll cut out the crack, epoxy in a patch then maybe put a few layers of glass over the bottom. also mcmaster has 3/16 uhmw poly for $145...

you did a fine job .. looks great and the effort shows. unfortunately you are going to find out that with low hp setups weight is your enemy. A boat with a narrow bottom print will run faster in the water than a wider boat but it takes nmore power to get it going and more time. A wide bottom gets on plane so to speak faster but will go slower but all require a certain hp for the combination to work. I am not sure I can give you an exact hp number per pound of weight .. hadn't never given it much thought becaus enever went below 35 hp with reduction. That is barely adequate for water operation on an approx 6 to 7 wide hull with a weight of around 200lbs for just the hull. It will carry two normal people ok but add a third or a good cooler or several bags of frogs and it is noticable quickly. .... hope ithis gets ya to thinkin .. but seriously your work looks good .. very good.

repairs are on hold till it's warm enough to use epoxy. I don't have heat in my garage plus I would rather do it outside. I've been looking for an aluminum hull or a jon boat I can cut up. I was hoping to try it on the snow this winter before I fixed it but we haven't had ANY! which never happens where I live.

very nice mini.i built a 4x8 for my son a couple years ago.lot of fun.i really like your reduction.very ingenious.i put a 20 hp onan on mine and it was heavy.made the boat kinda tipsy and it never really performed direct.when i was a kid growing up in the everglades road sign rudders were the norm.times change though i guess.

Riley my first airboat was a 4' 8" x 10 plywood boat. This was in the 70s. and in south fla. It had galvanized steel on the bottom. My dad built it and ran it for a few years and gave it to me when he graduated to a 6 cylinder aluminum boat. Once the sawgrass wears the galvanize off it is slick as glass.
