Yamaha F40SA — 40 HP
Yamaha F40SA is a four-stroke outboard motor rated at 40 HP (29,4 kW at the propeller shaft), successor to the F40FETS. Engine: SOHC, rzędowy 3, displacement 747 cm³, wtrysk paliwa. Dry weight: 91–106 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 S (15″ / 381 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: 414 mm.
Fuel consumption at full power according to Yamaha: 13,6 L/h @5500 obr/min. The F40SA is within the power range the shipyard recommends for the 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.
