Are the newer Bravo 1 lowers any more efficient than the old ones?

Not sure if nose cones are still being installed or not.

I thought it used to be if your boat ran faster than 80mph you would install them.

I was told recently you don't really need them unless you are running close to 100mph.

I have installed a Hydro-Motive on my B1 and noticed improved stability over 80.

Ive posted this before but here it os again, when my 272 baja only had 950 hp it ran 92 and change, well blended hydromotive nose cone, when drive was off being repaired i stuck my non nose cone drive on and boat would barely run 89, fwiw, smitty
