Outboard Top Speed World Record 200 mph Attempt

[LaveyT]

I hope the engine will be locked straight and a rudder used like Second Effort did it. Skeg or steering failure at 200 would be ugly. If it were me I would radio control it with a 150lb. sandbag in the cockpit until I knew it would not do the watoosie and explode into 1000 pieces.
Outrigger design can be safer but the drawback is it takes gobs of power to keep it up on the points.

Cool project indeed!
The radio control with a few go pro's in critical spots could save a life until you know it works. With today's cheap technology why not?
The watoosie...

I would think those round bars, on the sponsons, would add unwanted drag to your hull. Why not build aerodynamic shaped tubes to cut down on drag and air turbulence. After all you aren't using a big cubic inch car engine with gobs of hp and torque to push through the air. Or are you just running just a 1/4 mile. I would think aero drag is going to be a hurdle to overcome in the push for 200mph.

You don't know glory,do you? Sounds like a losers approach to me..

Regarding the aerodynamics, flying for a living and having a degree in aeronautics as well as physics please feel free to PM me and get me involved

150 lbs would only simulate the weight of the nads that will be needed.....just sayin.

The only test dummy we plan to use is Dan, myself or someone with a lot of money who will pay me to drive. R/C is good idea, but a real person can feel what the boat is doing or may be needing adjusted, we know the risk. I personally have drove a Pugh hydro over 160 mph all out and have run into the 7's at 140 plus in the 1/4 when I bought Doo Dad from Jon Wright. I also owed a Alcohol hydro and made many passes over 200 in the 1/4 mile with it. I know this is a different animal, but we wanted that. Dan and I are talking now about everything we still need, so we will probably be reaching out to a lot of you for help before long.

And the original is real close to you.

Very good choice of boat,miles safer than the current record holder.this boat with safety cell should weight around 400 lbs. Wally told me dixon had to really lower his engine height to stay on the water at 151mph he said they could have made 155 but he told them lets be happy and go home safe that was a #4 speed master 23 p 4blade that is a lot of extra......drag my guess525 HP. i cut a cracked Dewald 4 blade into a 2 blade 17 x10 & ran a very quick 121mph with a 2.4 no Nit #6 speed master on my 360 lb. hydro I'm guessing this outrigger with Dixons power head 11x25 2 blade would not miss the current record much i would say 170 ish but it will take 800 hp. t0 hit 200 it would not surprise me if they do it.im sure they will have a good safety cell .hope you guys do it. Peace steve

subscribed. . . . .not sure why, but I'm all ears.

3.5 Liter F1 V8 Evinrude. Someone has one sitting in a collection. I am sure if you ask, someone would enjoy having their engine being part of the attempt. They get it back after the run and now have the worlds fastest outboard in their collection.

No need to reinvent the wheel.

I know 2 people that have the F1 V8s. They only make about 390-400hp.

[Spectre Powerboats]

I need a minimum of 550 hp to break the record and approx. 700-800 hp to run into the 200 mph range. I will use the words "I think" also. As this is all a guess and done on paper, so till it gets to the water, it is a "I think."

That would not be me. I'd like to see the record set with a black motor.

Now you've gone and done it Joe. That comment will send the F1 V8 cult into a frenzy. Those engines have steadily gained horsepower among their worshippers since they were discontinued and are almost always guestimated at 500 or better. I fully expect to see a 700 horse number attached to a stock one sooner or later.

Everyone seems to forget most of them came with a dyno sheet.
