Boat was designed and built by Mark WIlson in Stuart, FL. Cummins powered with all the latest equipment. Built as a pleasure boat but also possibly to be sold as a military patrol boat. Fast and cool.

those are arneson surface drive. Never seen those little scoop on the transom, very intresting. Thank you for sharing

Arneson Surface Drives, (there are quite a few videos showing them in action here on KZfaq) are used in racing, and on high performance boats. There's a couple of fellows who run high speed crabbing boats near where I live, and they swear by them. Twin 400hp diesels are the norm. They cover as much as 120 NM a day. Saves them fuel, gives good performance can change a prop without removing the boat from the water and are of a very simple but robust design.

Looks like it goes pretty fast and kicks up a hell of a rooster tail! I heard surface piercing drives are challenging to learn and maintain but they are so cool 😎

No unice design, and this is a production model fram Arneson. Have been on the marked for ages. The scoops are intake for coolingwater for engines

These are Arneson surface drives popular in the 80s and early 90s. They are production units. Popular choice if you had a lot of horsepower on a heavy yacht and wanted to go like a true go fast boat in the day. Pair these with diesels or 1000hp gas engines and get that 50+ ft heavy boat to see 60mph or more.

Arneson surface drives. Mass produced.

Greetings from Indonesian seniors and thank you for the video, very good information about the development of shipping technology in this era

Really cool design, looks fast!

Due to the skegs, I think they are french. Arneson don't have them

I've only read about surface piercing propellers before, never seen them in real life but this winter, there's a boat with three of these next to my boat in the winter storage hangar. A real monster for which I wouldn't like to pay the fuel.

What these are. You mean a surface drive?

It would be very hard to reverse this beast because the transom is straight up and down and the wash would just bounce back pushing the boat forward.

Great Videos looks like a super nice setup should really get up & go like the way it is mounted to the transom looks very sturdy looks like it would take on some rough seas love your work thanx ALABAMA Smokeywilson

cool video, you should do more videos on the operation of those surface drive system. They look very interesting, like a mini version of those mounted on the Thunder Child II speed boat. What kind of boat are they mounted on, out of curiosity. 🤔

Very cool....

Hope they didn’t mount the “trim shaft” anodes on top of the paint. Might be why they aren’t showing much wear, compared to the others.

Thanks for sharing. Hazards of the job, you keep hitting your head when you crawl around under boats.

Thats a go fast boat I would 80+ on the water

Very fast Arneson Drives ! Very fast. A specialty of Pershing Yachts ~ their newer models automatically trim the drives up and down. Keeping the propeller hub itself level with the waters surface is the trick. Hub in air no propulsion, hub is water less efficient. You will burn a lot of diesel 200 gallons per hour or more on some models.

What the the zincs for?

nothing unique about them, they are production models from arneson, how do you not know this?
