Yamaha F50LC2 — 50 HP
Yamaha F50LC2 is a four-stroke outboard motor rated at 50 HP (36,8 kW at the propeller shaft), successor to the F50LETL2. Engine: SOHC, rzędowy 4, 8 zaworów, displacement 996 cm³, wtrysk paliwa. Dry weight: 111–119 kg.
A motor for remote control from the console — throttle and shift by cables from the control lever (mechanical controls), with mechanical or hydraulic steering in the boat. A proven choice for console boats that is simple to service. The model has electric start and power trim and tilt (PTT) — the motor angle is set with a button, even while underway.
Shaft length L (20″ / 508 mm). The shaft is matched to the boat’s transom height so that the anti-cavitation plate runs just below the water surface. Transom height for this shaft according to Yamaha: 527 mm.
Cowling colour: Pearl White (2) — matches light hulls and tubes.
Fuel consumption at full power according to Yamaha: 17,6 L/h @5500 obr/min. The F50LC2 is within the power range the shipyard recommends for the GRAND G420, GRAND S470 NL, GRAND S470 NS, GRAND S470 N, GRAND S420 NL, GRAND S420 NS, GRAND S420 N. At the GRAND BOATS Poland service centre in Łężyce near Gdynia we install the engine, do the rigging and choose the propeller. The engine is supplied in cooperation with an authorised Yamaha dealer; the manufacturer warranty (3 + 2 years) is carried out by an authorised Yamaha service.
