Abstract
A marine drive comprises an engine having a cooling system adapted to cool the combustion chambers, air intake system, and the power generator. Intake coolant passages are formed on either side of the crankcase so as to lie adjacent reed valves that are positioned within the crankcase. Cooling water is directed through the intake cooling jackets in order to dissipate heat that may accumulate in the intake valves. Another cooling jacket is defined adjacent a portion of a flywheel magneto generator assembly. Cooling water is directed through this generator cooling jacket to absorb heat generated within the magneto coil of the generator. Accordingly, the magneto coil is protected further from damage that may occur if it is exposed to excessive heat. This arrangement has particular advantages with direct-injected, two-cycle engines in which no lubricant is directed across the intake valves.
