IMCO SC Lowers worth a few extra MPH
 

I have a boat with standard lowers/nose cones. I'm seeing 98mph in optimal conditions with these lowers. I'm having the engines refreshed and I'm wondering if the SC lowers are worth the investment for a few mphs, I'm trying to hit triple digits. The boat is a Powerquest 340 Vyper with twin NA 588s. I think the HP is around 700.

I run them, I believe the bullet is more efficient than the B1 even with the added pecker...........:D..........I think there is speed to be had if you can raise prop shaft height without causing other issues
