Hi guys,

This is Eric Colby, Editor In Chief of SpeedBoat Magazine. It came to my attention through posts by some of you that the fuel-consumption information in the Mercury 600 vs. Ilmor 625 story may not have been accurate. I double-checked because we recently ran another boat with Ilmor 625s for the upcoming issue and we, in fact, incorrectly recorded the data on the OuterLimits. The correct numbers would show that the Ilmors are about 10 to 15 percent more efficient than the Mercs.

Sorry for any confusion this may have caused. I don't like reporting inaccurate data any more than you guys like reading it. We'll always strive to get it right.

Thanks for the overall positive feedback on the book.

Great to hear. Thanks for the correction.

Thanks for the update. Glad to hear the Ilmors are not as thirsty as I though after reading that article

soooooooo does that change the balance in favor of Ilmors vs the Mercs?

Great Mag b/t/w - keep up the good work.

Hey Eric,

By any chance would this be you doing your own stunts??

How does one suscribe?

Yep, that was me. We didn't win and didn't finish last either.

I just bought here last weekend. July edition. Havn't read the Merc Ilmor article yet.

But I did read the comparison with the single engine 30 footers you did. I liked it, but, why do you have the hp rating at 500, when these boats are running hp525's? I believed the 525's are rated at the prop shaft! Unlike the hp500 that are rated at the crank.

Thanks for the clarification. I think this confirms most of our suspicions.

HP525's are 500 at the prop and HP500's are 470 at the prop.
