Outboard Top Speed World Record 200 mph Attempt

I'd get the boat built first and run a s3000 on a small poof of juice and base line. Honestly this record is out of a 2.5's reach unless you can make it live on a tremendous amount of spray or a turbo set up. I'd skip that party and go right to a 3+ liter build. In a perfect world if Merc told me we'll talk after you set the record I'd build a Yamaha to do it.

It sure would be nice to see the existing record fall to another V8 OMC. Talk to Monty he may come on board for the challenge........:D

Good luck with the project.

Monty would be a good one also. I'm quite sure the V8 that Ray had on his Pro Gas boat would do the trick. I'd do my best to do it without the help of nitrous. Just brings in another set of reliability issues at a critical time.

Subscribed. Good luck and give it hell guys! Gary

Seem`s simple to me.

As much as I love Mercury, I agree 100% Karl would be rolling in his grave..... pussies

What a cool project. I am kinda sorta working on the same delio and has chosen Monty for my builds. I am using three of them on the back but will carry a lot more weight and is going after a different record, but a record nevertheless... All the best, keep us posted, I want to be there when you are going for the run.

BOY do I second that--- I bet ya he's doin backflips! Gary

4 stroke Hartley. Might as well push the entire effort three decades into the future. The way I see it power should be the very last consideration. Test the hull and driver with the most available power. Whether that be Merc, OMC, Yamaha or Scott-Atwater. Doesn't matter. You will not get corporate help from motor manufacturers. If you want help look at accessory builders. Props, clothing, oil, etc. they have nothing to lose if it all goes tits up. When all is good, the boat handles well at 160-170 or whatever the power you choose allows, then go after the power you need. The learning curve will be steep but you will know more about what you need after testing than you do now. My $.02.

:iagree: Now that is very wise advise!!!!!!!

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.
