An engine suitable for mounting in a small planing boat, which both lowers the center of the gravity of the boat, and enables a degree of freedom in arranging accessories. Balancers are arranged on the left and on the right of a crankshaft on a parting face of an engine. The engine is mounted in the body of the small planing boat surrounded by a hull and a deck. A starter motor and an idle gear of one balancer are arranged on the side opposite the starter motor, with the crankshaft between them. Also disposed between the idle gear and the starter motor is a cylinder. An oil tank is provided at the front of the engine, and two oil supply passages leading to the balancer supports are formed in the case of the oil tank.

1. Field of the Invention
The present invention relates to the arrangement of a balancer of an engine for a planing boat, and more particularly to the arrangement of a balancer for a small-sized planing boat.
2. Description of Background Art
The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
FIG. 1 is a schematic side view showing one example of a small-sized planing boat using one embodiment of an engine for a small-sized planing boat according to the present invention;
FIG. 2 is a plan view showing the same;
Referring to the drawings, an embodiment of the invention will be described below.
As shown in FIG. 1, the small-sized planing boat 10 is a saddle-type small-sized boat, a rider rides on a seat 12 on a body 11, and can operate the boat with a steering handlebar 13 provided with a throttle lever.
The body 11 has a floating structure in which a hull 14 and a deck 15 are bonded and between which a space 16 is formed. In the space 16, an engine 20 is mounted on the hull 14 and a jet pump (a jet propulsion pump) 30 as propelling means driven by the engine 20 is provided to the rear of the hull 14.
