I thought the VI used a forced oiling system so the gears were not immersed in oil like a Bravo. Windage of gears fully immersed can be quite high. A straight comparison of power in vs power out I thought I read in a magazine recently that the VI was more efficient than a Bravo.

But like others have said, any gain in efficiency is probably more than offset by increased weight.

Bravos eat less HP, but #6 drives handle more HP. #6 dry drives eat about 75 HP and Bravos eat 35HP. Not to mention the huge weight savings over the #6 drives.

For those of us that go about 100 hours per year, that would still be a yearly service every winter....... otherwise that 50 hours would end in the middle of the summer which would mean down time in prime season. So that sounds like yearly to me!!

very true.... but if you are pushing your bravo drive, you probably have missed time during the summer with that as well... i rather freshen every winter and not have to worry about it during the summer..

Oh yea, I have a Huber transmission and was concerned about how much power it was eating in my setup. Called, and had nice long talk with Huber. Nice guy. Says he did testing that showed his transmissions eat about 12hp, that's it.
