Re: WhirlWind Propellers Airboat Design Process

Thats not "heat". That is how the software they are using for FEA or CFDA shows either the stress map in the material / part or the displacement (think "flexing" or bending) of that material at a given load condition.

Re: ECOTEC 2.0 LTG SWAP

No worries on my end.

My recommendation to avoid that company will stay the same however. I personally paid him twice for the same "tune" and never got a proper one out the deal.

No sense in rehashing it out again here 7 years later either as its not going to help FishSticker out at all.

Re: 6.2 ls engine options

My boat is 19.5x8 with an enclosed cab. I run a big block 540 with 600hp/650ftlbs at 4800 where I turn my motor. My boat runs ground surprisingly well. Set up has a lot to do with your running. This boat runs ground better than my old 18x8. I don’t buy into the 1lb per hp guys will try and say you ...

Re: 6.2 ls engine options

19x8 going to be fairly heavy. 550 isn't going to cut it IMO. 4lbs of loaded boat weight per 1 hp for fairly good performance out of the water. 6lbs of loaded boat weight per 1 hp for marginal performance (you will be shaking the rake occasionally) Don't go off out in the middle of nowhere solo with...

Re: Dry ground setup?

Just need to have enough power. Doesnt matter how you get there really. As previously stated, 6lbs per hp or less. Lower always better. What engine you use to make the number you come up with based on the above is totally up to you based on a bunch of other factors that have nothing to do with makin...

Re: bulldozer prop.

Ha, definitely timeless good advice there! Glad I was able to pass it on and have it stick. I learned it through old timers and plenty of ideas that didn't work out so well.

On topic for a moment, you need more power. Put the turbo on and dont look back.

Best of luck!

Re: bulldozer prop.

Well, 4 falcons were equal to 3 maximus blades in my tests. The 4 falcons had a little steeper curve from a required power perspective and loaded my engine in an rpm range I didn't have enough fuel to cover so I went back to 3 max setup without losing any thrust. Cruise rpm was just slightly higher ...

Re: bulldozer prop.

As for RPM, I run around 5800 to 5900 with a 2.38 box and swing a 3 blade 80 inch maximus pitched at the "2" mark. So, that's in the RPM range you are talking about. You didn't mention which water Walker blade you have but if it's not a maximus you may consider going to 4 of those. I wouldn't trade ...

Re: Slick bottom fiberglass hull durability

No way in hell I would run slick bottom on St. Johns. Way too many areas with conditions that would simply destroy the bottom without UHMW. Most of the dykes you have to cross South of 192 for example are just covered in rock. I hit a submerged powerline wire support a while back at idle speed that ...

Re: Aluminum Rigging

Steel engine stand, everything else aluminum.

Oh, stainless cage wire too.

As previously stated, alum has literally zero fatigue strength so make sure the structure doesnt flex or it will, not if, fail eventually.

Good luck!

Re: 350 DD boat

Do you guys run a second spring?
Run 3 if you can. It's near certain death / fiasco if throttle sticks open in a lot of situations.

Inspect them before each ride along with rudder linkages too.

Re: New bottom paint thread

Any chance you know the coefficient of Static and Dynamic friction? Dynamic is more interesting. Also, thermal expansion numbers as well as abrasion would give us all the info needed to know if it stands a good chance of replacing UHMW. Lastly, peel strength would probably be mandatory given the hor...

Re: ECOTEC 2.0 LTG SWAP

If you do research I think you will find you mount the engine as low as possible for maximum thrust. Having the tip of the prop below the transom does not lose any measurable thrust and having the engine lower gives it a much better push point. This is totally true. High push point is something to ...
