OptiMax

125 HP - 75 HP

OptiMax mid-range engines provide real 1.5 litre muscle. You get unprecedented acceleration and power-to-weight performance, yet you can troll smoothly at low rpm…which makes it ideal for fishermen. Like all OptiMax models, you get up to 45% better fuel economy than traditional 2-strokes, plus a big 60amp alternator so you have plenty of power to run all your electronic gear, including fishfinders and chart plotters.
