PROPULSION UPDATE Caterpillar Announces 1.1 -Liter Family Of Marine Diesel Engines —Literature Available— Caterpillar Engine Division re- cently announced the availability of a new family of marine diesels, each with 67 cubic inches (1.1 L) dis- placement per cylinder. The new engines are aimed at powering smaller boats than previously served by the company's product RATING SUMMARY Ratings Engine Version High Performance Continuous 3116 TA 300 hp/222 KW 205 hp/152 kW 3116 T 250 hp/185 kW 165 hp/122 kW 3114TA 200 hp/148 kW 135 hp/100 kW 3114 T 160 hp/118 kW 105 hp/ 78 kW line. In most cases, they will com- pete in a power range, served until now mostly by gasoline engines. Both the 4-cylinder 3114 and the 6-cylinder 3116 are in-line, direct injected, four-stroke cycle diesels offered in turbocharged and turbo- aftercooled versions. Rated at 2,800 rpm, the engines are available in a high performance range from 160 to 300 hp (119 to 224 kW). The engines are designed to pro- vide optimum performance for boats in the approximate 25- to 40- foot range. The proper engine-to- boat matchup depends on hull char- acteristics and the number of en- gines installed. For optimum instal- lation flexibility, both seawater heat exchanger cooled and keel-cooled versions are available. "These engines bring a new stan- dard of diesel performance and reli- ability to the smaller engine user," said Larry Wilson, manager of product development for Caterpil- lar. "They have many of the heavy- duty features of the 3208 TA; and, like the 3208, the 3114 and 3116 are price competitive compared with NORTH AMERICAN MARINE JET INC. introduces the Jet that outpulls a prop! The ultimate propulsion system for your work boat. The all new TRAKTOR, developed by North American Marine Jet for work boat applications, produces more static thrust than a power prop at equal HP. Designed for max- imum pull at low speeds, it's the ultimate jet propulsion unit for both power and efficiency. TRAKTOR features include: • High thrust per HP • Very low jet RPM ... , ' ' All new steering and • Lightweight design reverse dual gate design • No hydraulics required • Factory assembled, complete Bolt on impeller blades 150 HP Cummins 3:1 Transmission.

(The 3208, rated at up to 375 hp, is well ac- cepted in boats in the approximate 32 to 60-foot range.) To ease servicing in tight spaces, both engines feature a removable plate for easy access to cam roller followers; intake and exhaust mani- folds are located conveniently on the same side; water and oil pumps are easy to reach. Caterpillar's worldwide product support is more complete and acces- sible than small diesel engine own- ers have been accustomed to. As evi- dence, the maker cites a present worldwide parts availability for ex- isting Cat Marine Engines of 98 per- cent in less than 24 hours and 99.6 percent in less than 48 hours.

The Chartlink delivers vital navi- gation information quickly and in an easy-to-understand form by translating loran or Satnav informa- tion into an easily recognizable elec- tronic plot of the boat's position, track of where it has been, and course to new waypoints. The visual presentation of charted information also makes the Chartlink a very use- ful tool for preliminary cruise plan- ning without the necessity of searching through a pile of charts. The Chartlink is operated by moving the tracking ball or pushing a button to call up various charts, zoom in or out or then to three or more levels of magnification, and store up to 100 waypoints, providing an instant determination of the lati- tude and longitude of waypoints and the boat's range and bearing to them. Charts that show major naviga- tional features are stored on low- cost cartridges that can hold an average of 10 charts. Charts for most parts of the world are available on cartridges.
