What is Arneson surface Drive?
The Arneson Surface Drive (ASD) is actually a version of what is referred to as the surfacing-piercing drive, and the name derives from its eponymous inventor Howard Arneson, an engineer and inventor who earned some 45 patents. The key to the success of any surface-piercing drive is that it reduces hydrodynamic drag.

Are surface drives faster?
Surface-drive motors have a much shorter driveshaft than long-tail motors. There are advantages and disadvantages to this design. In slightly deeper water, surface-drive motors develop more power and speed, making their top speed as much as 10-15 mph higher than a long-tail motor.
How does surface drive work?
Surface drives let the boat make better use of the power of its engine. Because the propeller blades break the water’s surface — they are called surface-piercing propellers — the engines powering them run under less load than with fully submerged props. Half of the propeller spins in the water.
Is Howard Arneson still alive?
Howard Arneson Obituary (1921 – 2020) – Novato, CA – Marin Independent Journal. Howard Arneson 5/25/21 6/15/20 Howard Arneson, a longtime resident of Northern California, passed away June 15, 2020 at the age of 99. Howard was an accomplished marksman, inventor and go-fast boating enthusiast.
What are pod drives?
Pod drive is a marine propulsion system where the gearbox and drive is mounted right beneath the boat in the water. They steer on a large axis, and when mounted in twin and triple set-ups can be used with a joystick for ease of parking.
Whats better surface drive or long-tail?
Surface-drive motors have a much shorter driveshaft than long-tail motors. In slightly deeper water, surface-drive motors develop more power and speed, making their top speed as much as 10-15 mph higher than a long-tail motor. The shorter driveshaft doesn’t offer quite as much reach during the most rugged conditions.
Is long-tail or surface drive better?
If you tend to go through conditions like these, a long-tail motor is probably your best choice. Surface-drive motors are great for those who tend to take longer hunting trips in slightly deeper water. This mud motor type can reach higher speeds, but it doesn’t have quite the leverage that a long-tail mud motor does.
Are surface drives better?
Overall from a Surface Drive system, you can expect greater fuel efficiency for a boat capable of achieving a cruising speed higher than 35/45 knots, zero cavitation and shallower drafts, less maintenance and exceptional astern performance, making Surface Drives the smart choice.
How do surface drive mud motors work?
How does a mud motor work? The typical mud motor unit consists of an air-cooled engine mounted to an elongated direct drive shaft and steel prop. This single motor bolts directly onto the transom of the boat and doubles as a pivot point for the motor, making it easy to switch your navigation in a pinch.
Are pods good for boats?
So even with all that technology you can add onto a shaft drive boat, the benefits of the pod drives remain that they have better fuel economy and increased handling and performance…with certain size limitations. The fact of the matter is that some sizes and types of boats are better matched with pods than others.
Why do boats have pods?
Hydrodynamically, a pod drive is more efficient because its thrust is parallel to the yacht’s hull (with no down angle like conventional running gear) and each pod’s two propellers rotate in different directions, canceling out much vibration and all rotational energy.
How did the Arneson Surface drive get its name?
The Arneson Surface Drive (ASD) is actually a version of what is referred to as the surfacing-piercing drive, and the name derives from its eponymous inventor Howard Arneson, an engineer and inventor who earned some 45 patents. In the early 1960s he invented a device that automatically cleaned pools.
Is the Arneson drive half out of the water?
Arneson’s patent is for a “shroud-enclosed, inverted surface-piercing propeller outdrive.” Regardless of what you call it, the whole idea of a propeller running half out of the water seems counterintuitive. Wouldn’t you want it submerged so all the blades are in contact with the water? In actuality, no.
What are the advantages of the Arneson drive?
Another advantage of the Arneson Drive is that like stern and pod drives, the drive unit is laterally articulated so when you turn the wheel you change the direction of propeller thrust, instead of deflecting it off a rudder. This creates much greater steering accuracy and response as well as increasing efficiency in turns.
When did the Arneson drive first come out?
Thanks for watching! When it was first introduced in 1980 the Arneson was every bit as revolutionary as the pod, and many thought it would eventually supplant the conventional underwater propeller, and possibly even the stern drive, as the preferred means of propulsion in pleasure boats.
