Caveman, did you ever get your boat to 100 this year?

101 Would you beleave I had 2 1/2 quarts to much oil
per engine.

Randy at Cobra power got me from 97 to 101
By measuring the amount of oil in the engines.

Now I am going into this season with Blowers and
Intercoolers. I hope it stays together.


Heres a good Surface drive Thread.http://www.offshoreonly.com/forums/s...s+on+v+bottoms

Somewhere, I read that most of a propellers thrust is generated during the 3 and 9 positions (think about a clock). The rest of the rotation, while generating some thrust, is "waste". With the top of the prop out of the water, the inefficient part is reduced.

I have also read that surface drives do not provide the bow lift a conventional I/O can. A hull with some rocker is better for a surface drive.

Two others that have already been mentioned is the reduction in power robbing gears and less drag.

And best of all, BIG ROOSTERTAILS - show 'em Cuda!

If Rik sees this and posts, we will know all.

RonP -- What the heck are THOSE?!?

Question: Did anyone make these before the Arneson/Borg-Warner?

Albert Hickman is the innovator behind surface piercing propeller operation. Circa 1914.

Hickman also designed the "Sea Sled" which later was modified and became the Boston Whaler.

I remember a quote from Howard A. back in the day referring to fully submerged drives That the drives accounted for 55% of total drag to the boat. That was in the days whan a 38' scarb or a 38' cig were the top race boats

It was a lomg time a go but the best as I can remember Paul Cook and Howard Arneson were in a partnership on a surface drive. They both came to different views and parted ways Hence Kamma drive and arenson drive.
Somebody correct me if my memory is incorrect
I do remember Howard Arenson and Sammy James winning races in and Arenson driven scarbb. That was the beginning of the drives popularly late 70s or early 80s

Also second effort was making a converition plate to replace a jet drive,I think thet did counterfiet the arenson drive There are still some out there
