Yamaha F15SPHA — 15 HP
Yamaha F15SPHA is a four-stroke outboard motor rated at 15 HP (11,0 kW at the propeller shaft), successor to the F15CEHPS. Engine: SOHC, rzędowy 2, displacement 362 cm³, 1 gaźnik. Dry weight: 51–61 kg.
The tiller version — you steer directly with the handle, with throttle and shift at hand, no console or cables. A practical choice for inflatables, tenders and smaller RIBs. The model has electric start and power tilt (PT).
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: 438 mm.
Fuel consumption at full power according to Yamaha: 5,3 L/h @5500 obr/min. The F15SPHA is within the power range the shipyard recommends for the GRAND S370 N, GRAND S330, GRAND S300. 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.
