Yanmar Powered Fountain 48EC Boasts Speed and Fuel Economy

All too often, cruisers have to choose between the performance and luxury of their boats. Equipped with triple engines from Yanmar, the Fountain 48EC combines the two, giving enthusiasts a lavish ride with incredible fuel efficiency at high speeds.

Producing a powerful 480 hp each, the Yanmar 6LY3-ETP engines turn stainless steel 6-blade propellers coupled to surface drives. Weighing significantly less than other engines in the same horsepower range, the in-line six-cylinder diesel, surface drive and marine gear package total approximately 1,900 lbs. each.

Long distance runs are possible with the express cruiser's 460 gallon fuel capacity. In a recent test, the 48-footer averaged over 1 mpg while cruising between 33.5 mph and 54.7 mph @ 2,000 rpm to 2,800 rpm. The boat had a top speed of 65.6 mph @ 3,390 rpm and accelerated from idle to plane in 9 seconds flat. It was tested with front and side curtains to simulate a fully-loaded craft.

Yanmar distributor Mack Boring & Parts Co. supplied the engines for this installation. "The Fountain 48EC has exceptional maneuverability and drives unbelievably well," said Jack Law, marine sales representative for Mack Boring. "Its extremely fast cruise speed and economy of operation set it apart from the competition."

The 6LY3-ETP has the dimensions of a competitor's 300 hp engine. With a superior power-to-weight ratio, it is the lightest and most compact engine in its class.

The engine complies with EPA Tier 2 regulations. Its high pressure, torque-inducing, electronic governing fuel delivery system offers improved fuel consumption, reduced noise at idle and decreased fuel odor and smoke. The electronic control also provides constant power regulation, synchronizes engine speeds and monitors all critical engine information.
