  • Top-down serviceable outboard motors
    Patent number: 12208876
    Abstract: An outboard motor has a top cowl and a service lid on the top cowl is movable into and between a closed position enclosing the powerhead compartment and an open position providing manual access to the powerhead compartment from above the outboard motor. An engine is in the powerhead compartment, wherein a peripheral gap is defined between the top cowl and the engine. A serviceable engine oil device is in the peripheral gap and is manually accessible from above the outboard motor when the service lid is in the open position. A serviceable transmission fluid device is in the peripheral gap and is manually accessible from above the outboard motor when the service lid is in the open position. A serviceable gearcase fluid device is in the peripheral gap and is manually accessible from above the outboard motor when the service lid is in the open position.

  • Air intake plenum for attenuating sound from a marine engine
    Patent number: 11598269
    Abstract: An intake plenum is for a marine engine, the marine engine having first and second throttle devices for controlling flow of intake air to the marine engine. The intake plenum has an airbox providing an expansion volume, first and second inlets that convey the intake air in parallel to the expansion volume, first and second outlets that convey the intake air in parallel from the expansion volume to the first and second throttle devices, and first and second Helmholtz-style attenuator devices located at the first and second outlets, respectively. Together the first and second inlets, expansion volume, and first and second Helmholtz-style attenuator devices are configured to attenuate different frequencies of sound emanating from the marine engine via the first and second outlets.
