Bravo to Arneson ?
 

What is the max power these conversion drive setups will take?
Thanks

Straight from their website!

"The ASD6 Kit comes with a one year warranty with a 750 lbs of torque rating along with a transmission that is suited for the application."

I thought they offered the 7 as well?

Drive Identification

ASD6

ASD6, comes in right and left hand rotation with the following gear reduction/overdrive options: 1:1, 1.32:1 and 1.57:1

The ASD6 comes in choice of Bronze or Aluminum. In-Line model not shown here yet... Note: The Arneson Borg-Warner 1721 model looks exactly like the unit shown. The name "Arneson Borg-Warner" is cast into the Thrust Tube below the trim cylinder. This is important to know when ordering spare parts.



ASD7 (1600)


These drives were the predecessor to the ASD8 Drop Box Drives. The drop box has 16" centers hence the term 1600 is cast into the drop box. If you have an Express Cat, odds are there are the drives that are on you boat.

The 1600 combines an aluminum 16" centerline drop box assembly with the 1721 Thrust Tube assembly made of bronze. The propeller shaft is the same as the 1721 and some came with the short 4" hub other the long 6" hub. The reduction ratio's are non adjustable, meaning a 1.32:1 box cannot be made into a 1.5:1 and vice versa. These are good reliable units, parts are still available.




ASD8

ASD8 In-Line Unit. Made in Bronze for Strength and corrosion resistance. Used with reduction gear on marine engines for rotation and torque.

ASD 8 16" Drop Box

ASD8-6 Drop Box Unit. Made of Almag Aluminum for light weight and corrosion resistance, the newest Arneson Surface Drive brings new features to the line of drives. The ASD8-6 has RH or LH rotation standard, removing the need to counter rotate an engine. The ASD8-6 has a smaller drop center distance allowing the engine to be mounted lower in the boat, placing the CG in a more ideal location for better handling and turning. The ASD8-6 comes in 1:1, 1.25:1 1.32:1, 1.56:1 and 1.625:1 reduction/overdrive ratio's.

ASD8-10

ASD8 10" Drop Box. Drop box is made in Almag and the 10" drop center box has the following reduction/overdrive options: 1:1, 1.1:1, 1.21:1, 1.32:1, 1.41:1, 1.53:1, and 1.61:1. Units can be mounted vertical or at 31° or 52° angles to alter the propshaft centerline. There are three propeller shaft spline options for the ASD8. 19 tooth, 25 tooth and the Mercury SSM#6 26 tooth spline. Any of these will fit the ASD8 Drives.

There are two rudder options for the ASD8, the single fin, as shown in the ASD8 In-Line and the Dual Fin shown in this photo.



ASD10 Inline Drive Unit

ASD10 In-Line Drive Units. The ASD10 has a 2,000 lb torque rating. These drive models rely upon the reduction and propeller rotation being handled by the marine gear.



ASD12

ASD12. The ASD12 is made in Bronze and has a torque rating of 4,800 lbs of input torque. The rudder fin is removable for easy boot changes. The reduction and rotation change come from the marine gear in the boat.



ASD14

ASD14. The ASD14 is made in Bronze and has a 8,000 lb torque rating. The fin is removable for easy boot changes.

ASD16

ASD16. The ASD16 is made in choice of Bronze or Almag. The unit has a 16,500 lb torque rating. Steering fin is removable for easy boot changes.

Rik will chime in and answer officially but there are boats pushing much more then the ASD7M bravo conversion is rated for with success!

The #7M is warrantied to 850 hp.. We replaced the ASD6 Kit with the #7M Kit so don't worry about what the web site says.

Rik, I'd assume a lot of people pushing more through them. What do you suggest to the folks running around with 1000+ out of curiousity?

In a 38' V bottom.. The #7M's. 85% of the customers as in this power and boat range.

Rik how much farther do the props stick out behind the boat than with a bravo?
Thanks
