Replace the standard 3-blade propeller on your work boat with Federal's "Power

Thrust" and you can expect more power and much smoother operation. In a size for size exchange, "Power Thrust" offers better maneuvering and handling characteristics, reduced engine wear and greater fuel economy. The heavy duty construction of this exceptional propeller was engineered for cutting through mud and debris with- out damage. Costly haul outs and down- time are practically eliminated, especially if you order your "Power Thrust" in super strong Ni-Bral. Available in all alloys through 96". If you're concerned with eco- nomical, efficient operation, more power to you. See your marine dealer about

Second, to test the marine fire re- sistance of aluminum fuel tanks, the

Aluminum Association retained Trop- ical Marine Testers, Inc. in North

Palm Beach, Fla., to conduct a fire test as specified in Standard E-3 of the Marine Department, Underwrit- ers Laboratories (formerly Yacht

Safety Bureau).

The standard requires that a test tank filled to one-quarter capacity with gasoline be subjected to a spe- cific temperature range during a 2 y2 minute test sequence. The tank is suspended over a pan of flaming gaso- line. A temperature sensor located one inch from the bottom of the tank must indicate a temperature in the 950°F-1450°F range after 45 seconds of test. Within 75 seconds, the sensor must indicate a tempera- ture between 1250°F and 1550°F, and continue within this range for an additional 75 seconds.

The test 'fuel 'tank fabricated with

Y\ -inch marine aluminum alloy suc- cessfully survived the test procedure intact.

U.S. Coast Guard approval of the use of independent marine fuel tanks fabricated with J-^-inch marine alu- minum alloy applies to all commercial boats, including offshore crew and supply boats.

The Coast Guard regulations au- thorizing the use of these aluminum fuel tanks are scheduled to be pub- lished later this year in the Federal

Register.

Independent Aluminum

Marine Fuel Tanks

Approved By USCG

The Marine Safety Council of the

United States Coast Guard has ap- proved the use of independent alu- minum marine fuel tanks for com- mercial service. The Coast Guard's authorization covers fuel tanks fab- ricated with 34~inch Type 5086 alu- minum alloy and other alloys accept- able to the commandant.

To qualify for Coast Guard ap- proval of their commercial use, the aluminum marine fuel tanks were determined to be corrosion resistant in a marine atmosphere.

The following steps were taken to qualify the aluminum alloy for

Coast Guard approval:

First, the Aluminum Association supplied the Coast Guard with docu- mented, historical evidence of alumi- num's ability to resist corrosion. The documentation included written testi- mony of individual boat owners over the last two decades.
