Not another like it, and honestly not many ilmor set ups out there in the first place. Seen some on formulas, eliminators, etc but nothing really comparable to the velocity, would really need the numbers from a fountain with them to compare. The boats dry weight is right at 8k if I'm not mistaken. I may be wrong but I also believe I was quoted about a 300lb weight reduction per motor just ilmor vs merc.

ive been told there was a 700 NXT boat that ran 115 and a 565 xr that ran 100mph. That boat must have been dialed in perfectly but still. What is the gain on the arneson vs a standard bravo style anyways? 5mph? 10mph? Never did a conversion, the arneson I've owned was done new so I have no clue.

Didnt know they made a surface drive, I see the cleavers....huh. I'm not all that familiar with imco but if that is their beefy drive I heard that one too scrubs some considerable speed vs just even a standard xr. Probably the same boat I'm in with konrads?

Never drove or been in a #6 boat, but just drove our Newley acquired slingshot with arnesons the past week and I’m sold on them. They plane off a little slower, but always pop up with ease. Docking is better than our bravo boat. The roost is insanely cool, and they are bulletproof.

Well, ask Jeff Tibbe how much he gained when he put Arnesons on his 32 Active Thunder.

We see a lot of customers with Bravos gaining 10 mph in the mid range and top end and the drives on this boat are slower than the same boat with Bravos so I don't see a problem with that estimate.

If it were me I’d try refining the current setup. Get the X up with boxes, blueprint the lower, try some props. Then I would tune up the ilmors to get where you want. They can get to near 800hp with a build.

Konrads are up as high as they can go, in fact they don't even manufacture the shorty that is on them right now. Right now running 5 blades to even just get on plane. I'm convinced they really don't have anything left in them after talking with all parties involved, including Konrad. I will not crack the motors until they need to be rebuilt and at that time they will go to Ilmor in Michigan. I have another boat with custom motors and every time I go custom I seem to get problems. The whole reason I purchased this boat is because it had factory assembled low hour ilmors. I have had a bad run recently with some quality performance shops.

which boat did you buy, I was looking at a few of them that were for sale a few months back. What power?

I struggle to see the value in either option, sticking $50k in drives in a $100k boat just does not make sense to me. If it were me I would enjoy the boat for a few years and then change boats. There will always be someone faster.
