I put one on my Baja 272 back when it ran mid 70's years ago, it seemed like it made it wander and steer alot more evil until I put full hyd on it, I didn't see any speed gain then. Fast fwd to 2005 or so when I built my motor up to 950 hp, boat ran 92 running light/89 loaded down with Bravo with well blended hydromotive nosecone. I broke a shaft in my drive and put on my spare without a nose cone, boat would barely break mid 80's and I think hit a best of 86-87 or so if I remember correctly, put the other drive back on when I was done fixing it, speed was back, fwiw, Smitty

Is there any difference with the older blunt bravo case. I'm thinking that it would benifit more than the newer case design. I'm thinging about adding a set on my 89 Formula. With the new engines I'm hoping to be in the mid to upper 70's.

I might have a pair of Hydromotive nosecones for the old style Bravos if you're interested. I bought them thinking they were TRS but they weren't.

Thats what happened on my panther (twins). I was running 92-93mph best lightly loaded with bobs nose cones. Broke a skeg off one drive and last winter built 2 non nose cone lowers and never broke above 89mph all year. 86-87mph was more like it most the time. It also did the same 86-87 no matter how many people or how much fuel I was carrying. Just like hitting a wall. I might have lost 1mph or so due to the lower water pickups, but most I felt was due to the cones being absent.

I used to run a Check 251, with the short bullet 88 lower. Hit a wall at 78mph, till I put the hydromotive cone on it. Then it went 83. I ended up close to 90 using a newer lower (longer) with the hydromotive cone, before I sold it. That was with 686hp. The shorter one will definitely hit a wall at slower speeds.
