I have a 2017 30hp 4 stroke, tiller. When the motor is put in forward and idling, I hear what sounds like an internal knocking sound when the engine is idling. The sound seems more pronounce on the port side of the engine. I cannot hear the knocking sound when the engine is revved up to a higher rpm. This is present when running in the lake or on earmuffs. The sound is not present in neutral or reverse. I realize the engine is still under warranty. I just wonder if this is something I should bring it to the dealer for. Any ideas would be appreciated.
