Caterpillar Announces 1.1 -Liter Family Of Marine Diesel Engines

—Literature Available— Caterpillar Engine Division recently announced the availability of a new family of marine diesels, each with 67 cubic inches (1.1 L) displacement per cylinder. The new engines are aimed at powering smaller boats than previously served by the company's product line. In most cases, they will compete 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 turboaftercooled 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 provide optimum performance for boats in the approximate 25- to 40- foot range. The proper engine-toboat matchup depends on hull characteristics and the number of engines installed. For optimum installation flexibility, both seawater heat exchanger cooled and keel-cooled versions are available.

"These engines bring a new standard of diesel performance and reliability to the smaller engine user," said Larry Wilson, manager of product development for Caterpillar.

"They have many of the heavyduty features of the 3208 TA; and, like the 3208, the 3114 and 3116 are price competitive compared with other diesel engines." (The 3208, rated at up to 375 hp, is well accepted 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 manifolds are located conveniently on the same side; water and oil pumps are easy to reach.

Caterpillar's worldwide product support is more complete and accessible than small diesel engine owners have been accustomed to. As evidence, the maker cites a present worldwide parts availability for existing Cat Marine Engines of 98 percent in less than 24 hours and 99.6 percent in less than 48 hours.
