Friend of mine put two of them on a 36 Apache with -2" lowers, runs as fast as he did before. Talked to him the other day and he said 150hrs and no problems. Loves them! He is running 825hp per side, Vortec chargers, can run 95mph on a good day, and he doesnt baby them!
I am setting another friend up with two of them for his 36' Baja, with boxes and transom assemblies. I think Imco has a winner. If you want, pm me I can shoot you a price on what ever you need.
Thanks
Dick

Arent these the same as B-Max's?

No.. not at all like a Bmax. Use straight cut gears like the XR, but much larger and stronger. All new larger shafts and lower gears are larger. The lower bullet is larger, but with proper setup, speed loss can be minimized.
You can go to Imco's site and take a look at the construction of these drives. Been out over a year and no gear failures. People are starting to trust them and like them!!
