I am looking for real experiences from real users not catalogue or www. printed information.

any conclusion?
strong?
easy to maintain?
long-life?
are they like experimental drives or do lots of people use them?
any input about these drives would be perfect.

thnx

He dry sumped my # 6 speed master's drives, never had a problem with them, gained 10 MPH with them for $20,000.00 lets see thats $2000.00 per MPH, cheaper than $4000.00 per MPH in engines. Always buyer beware !!

increasing efficiency(sp) of what you have has proven to be more cost effective than overcoming the lack of it with horesepower.

I am not talking about upgrading the drives , companies background or how pro's they are.I am wondering about these strange looking drives.how are they? are they evolution of merc 6 drives?!? dont think so...these are completely different:

pics are taken from their website:

bonus is that you can also adjust the vertical height and play with the effective x dimension,it's like having a outboard jack plate on your I/O

are these drives for only xxtra high budget racing boats?
r they experimental?
is there anyone using them on their pleasure boats?

Catmando thnx for input. I have spoken many times with both of them here in forms.I know they are very friendly people.Will talk to them for sure but all I want to do is to collect some extra info about the drives..
I mean if we make a line starting with
:bravo-1
:aftermarket bravos
:#5
:#6

are these drives coming after #6 drives ? or are they alternative to #6 ? or are they somewhere between #5 and #6?

hummmm...there are pros and cons for them...cat, v, stager,HP??? i may know a thing or two about gears and fluid dynamics

Sorry for the correction, but the Hallett 54’ has Arneson drives.
