Well, first thing you should probably consider is that you don't have enough prop. Unless you want to run 100+ mph I'd look at adding another blade. A 3 blade @ 82 just isn't enough for the engine specs you list. My little tiny 122 cubic inch engine runs a 3 Blade 80 inch with wider blades than thos...

Why?

Bucked aluminum rivets, no issues ever.

Its a wheel that can't be made more round imo.

Weight alone would be a hard pass for me.

Let us know how it works out if you try it!

Funny thing, I only see people doing crazy stuff on one "side". Anyone on here looted any stores lately? "Come on, man!" Everything, absolutely everything improved under Trump. Only thing that got hurt? Your "feelings." I can live with that. Trump kept nearly ALL of his...

This time, more than ever, it is critical you all go vote.

Nothing else, just go vote.

My opinion is not enough power and not enough prop. You would do well with 4 blades the longest length possible and at least 500 hp. Not sure what you think that 502 puts out, but, if its down a bit then a heavy rig will struggle. The air flow path is a valid think to look at as well, it does make a...

Curious what the experts have to say

Easy, not enough power at 4700 rpm. That could be under 300hp pretty easily based on exact build.

No question, bucked rivets are the best method to use.

Why? Weight, cost, performance, etc.

Only negative is that it requires another person and the right tools.

Right, you have a ton to learn. My suggestion is to enroll in a general engineering undergraduate program before burning much more on this. Sprinkle in a couple finance courses from a business major while you are at it. I see you write many times, "I am willing to pay...." Well, you are pr...

and my cruise

As pitched in this photo, what is your max RPM?

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.

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.

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 ...

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...

About 300 hp minimum without needing to under pitch.

You probably dont realize it but you just necro'd a post that is almost a decade old......

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...

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!

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 ...

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 would...

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 ...

Stick marsh to the area you are talking about can be seen in this video.

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!

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.

Looking good to me!

Welds are pretty solid too. Have seen a lot of stainless rigging over the years with popcorn madness. Good to not see that on yours!

My personal favorite....
