Re: What drives?
tachyon,
Thanks for the compliment, it's rare that my memory works very well anymore
All Speedmaster drives are designed to run on the surface to achieve maximum speed, I have mine set at 3/4's of an inch ABOVE the bottom of the hull. By removing the skeg, like on the Bacardi Boat, you get rid of the drag of the skeg. Hey look, guys were getting significant increase in speed by switching to the swepped back skeg on a number 6, gives you an idea about how much drag there is on the skeg. On a conventional V-bottom boat, I don't think there is much to gain by switching to an Arneson, but on a step-bottom V, I think there is more speed because you don't need to "lift" the nose out of the water to gain speed. The problem with the Bravo Drives is that the prop must be TOTALLY submerged in the water for them to stay together.
There is a guy on the lake here (Lanier) that switched to an Arneson from a Bravo and actually LOST 15 mph on a cat hull. I don't know all the particulars but that is what I heard from some VERY reliable people.
I'm just happy that my 6's will hold up to my new CHIEF ENGINES. I'm not trying to out-run anyone, I just want to ENJOY myself.

I know that Geoo could answer that question. The only issue that I can see is having the prop wash hit the transom when reversing.
WV-whats the hardy dam run?

Re: What drives?
Last weekend where out and had reserved slips in a crowded Marina
The Dockmaster decides to stick me in the tightest slip near the Gas dock.
Wants me stern in. After three attempts. Just drive it bow in he says.Will swing it with ropes. You all know how it gets. Everyone out with there boat hooks. Ya cant hear nothing over the 15% overdriven Blowers.
Backing up is horrible. Cutting tight corners is accomplish by one in
forward the other in reverse. Knowing where the drives are positioned
is half the battle. But even when dead on straight reversing still swings
the bow.
The wifes Zanex Helps when in tight marinas.
