Arneson fixed drive question

Need a little help understanding here. On an Arneson drive like the one in the picture, how does the hydraulic bottle jack compensate for the arc of motion at the attachment point to the shaft...

Hmmm, no takers yet? Ok, I'll start and if I'm way off someone call me on it.

Rudder vs Vectored Drive

Been searching around with little success on why the offshore racers with surface drives use rudders instead of vectored drives. What is their thinking?
I have my own ideas why it is, but would like...

Recently I was talking with a local boat shop owner about this. He had a couple 1970's vintage boats in the 20-25 foot range using twin SBC with alpha drives turning in the same direction. He said at...

Yeah, I recognize that. I think gear ratios will be something I'm going to have to mess with no matter what. With the 6500/1.76 combo and a 34" prop that equates to 107MPH. That puts me square in the...

In the various searches I've done it seems most guys redline their engines in the 5500 to 5800 rpm range, maybe 6000. With a 1.5 ratio that gives us a prop speed of 3667 to 4000 rpm.

One of the...

Do surface drives require the same gear reduction seen in Bravo's? I see where they run 1.65, 1.50 or 1.32 if not mistaken. I believe the last two ratios are what's most common. What is right for a...

Here's how one guy did it. Not at all how I would do it but, it worked for him. He essentially sliced the boat in two across the stern and spliced in a section.

You might be right although my estimate should be pretty close. The factory brochure claims 3500 Lbs with a SBC and Alpha drive. The intent is to build a very light and minimalist boat. I don't plan...
