Engine noise on large boats can make it difficult to relax and enjoy your time on the water. Suzuki outboards run unbelievably quiet, so much so that some users have thought their outboard was actually switched off. They may be exaggerating, but Suzuki outboards have long been noted for their quiet operation. Suzuki’s engineers go to great lengths to incorporate methods and technologies designed to keep outboard operation as quiet as possible.
For example, the DF200AP/DF200A/DF175AP/DF150AP models are fitted with a resonator on the intake manifold. Often overlooked as a noise source, air sucked into the intake manifold at high velocities can generate a harsh noise. Adding the resonator reduces such noise, keeping operation exceptionally quiet.
