ABSTRACT:
A marine engine incorporates an engine body defining first and second bearing sections. A crankshaft is journaled at the first bearing section for rotation about a first axis extending generally vertically. A balancer shaft unit is journaled at the second bearing section for rotation. The balancer shaft unit includes two balancer shafts rotating about second and third axes both extending generally parallel to the first axis and also parallel to each other. The crankshaft rotates the balancer shafts. The balancer shafts have balancer weights. A lubrication system delivers lubricant to the first and second bearing sections.
