Caterpillar builds propulsion systems!

Gears and accessories matched to prime power units foryourwork boats!

Time saved is, in itself, enough to make a power "system" worth investigating. One source means one contact, one responsi- bility, with less time spent.

But time saved is only one of the ad- vantages of a system. Coordinated com- ponents, built to one quality standard, deliver trouble-free power throughout a longer service life. Problems of vibration, torsion, noise, speed have been solved for all parts of the system in the factory, not on your boat. Installation design is for all units in the system instead of individual items; and identical warranty and society classification are provided for all.

Caterpillar supplies "systems"—engines, gears, generator sets and attachments carefully mated to each other—systems that range in size to 11 25 HP (continuous flywheel) in single installations. Each fea- tures moderate rpm operation . . . con- servative BMEP ratings . . . four-stroke cycle dependability . . . long-life. Each is backed by the exceptional parts and service capabilities of the Caterpillar dealer net- work.

Before you invest in parts for a propul- sion system . . . investigate a complete system. Your nearby Caterpillar dealer has details or write Caterpillar, Industrial Divi- sion, Dept. 682M, Peoria, Illinois 61602.
