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 manual pull start and manual angle adjustment (trim in several positions).
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: 558 mm.

At the GRAND BOATS Poland service centre in Łężyce near Gdynia we install the engine, do the rigging and choose the propeller.
