Electric engines are becoming increasingly popular for use in small fishing boats or inflatables in fresh water. They are extremely quiet, do not smell and are ideal on small lakes. This engine is particularly efficient and the noise level never exceeds 40 dB. It has a telescopic throttle (except for model 33S) that extends to 14cm. The engine housing is prot-ected from harmful UV rays and extremely strong. 2 large screw fixings hold the engine securely on the stern of the boat. For optimum efficiency the 90° propeller can be set in 9 positions.
