Yamaha FL350ES2 — 350 HP
Yamaha FL350ES2 is a four-stroke outboard motor rated at 350 HP (257,4 kW at the propeller shaft). Engine: 24-zaworowy, DOHC z VCT, 60° V6, displacement 4256 cm³, wtrysk paliwa. Dry weight: 293–304 kg.
A motor with integrated Yamaha DES digital electric steering: no pump or hydraulic hoses in the boat, a lighter installation, precise handling and ready for Helm Master EX with a joystick. Throttle and shift are digital (Drive-by-Wire). The model has electric start and power trim and tilt (PTT) — the motor angle is set with a button, even while underway.
Shaft length E (35″ / 889 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: 894 mm.
A counter-rotating motor is paired with a standard-rotation one — in a twin installation it balances the torque and makes the boat easier to handle. Cowling colour: Pearl White (2) — matches light hulls and tubes.
Fuel consumption at full power according to Yamaha: 113,1 L/h @6000 obr/min. 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.
