PROPULSION UPDATE Arneson Surface Drives Offer Performance With Reliability —Literature Available— Arneson Marine, Inc., Corte Ma- dera, Calif., are the manufacturers of a state-of-the-art marine propul- sion system, Arneson Surface Drives, which utilizes surface pierc- ing propellers to provide propulsion for all craft from 16 to 150 feet. Increasingly popular with build- ers intent on achieving outstanding performance with reliability, Arne- son Surface Drives (ASD) have found particular favor with govern- ment, defense and commercial oper- ators around the world. Arneson Marine offers eight basic sizes of the propulsion systems (ASD-6, -8, -10, -12, -14, -16 and -18) differentiated by input torque capacity (See Speci- fication Chart). Production ASD units are available for use with gas, diesel and gas turbines up to ap- proximately 5,000 hp. According to a recently published brochure from the company, Arne- son Surface Drives offer several pro- pulsion advantages for all types of vessels. Some of the advantages listed include: higher top speed and increased efficiency; excellent ma- neuverability and steering control; flexibility of engine placement; min- imum noise and vibration; easy "in- the-water" propeller changes; and ease of installation and alignment. Arneson Marine has expanded their performance line to include drop-center versions of the models ASD-8 and ASD-10. These units are available in 10-inch and 16-inch off- sets, and with several integral re- duction ratios, in lightweight cast aluminum or sturdy manganese bronze. ASD's surface-piercing pro- pulsion technology provides effi- cient use of engine horsepower and eliminates the drag of underwater gear. The California-based manufac- turer has distributors worldwide in such countries as Australia, Brazil, Indonesia, Italy, Sweden, Switzer- land, Taiwan, Thailand, Turkey and the U.K. Additionally, Craig W. Dorsey, president of Arneson Ma- rine, Inc., recently announced the signing of an agreement with Sec- ond Effort Performance Products, Inc., which will transfer their sur- face drive manufacturing capability to AMI for an undisclosed amount. The agreement includes all invento- ry, patterns and tooling for Second Effort Models 1050 and 1600 sur- face drives. Arneson Marine is offering a free brochure fully detailing the per- formance and reliability of their ASD marine propulsion systems.
