PROBLEM TO BE SOLVED: To miniaturize an outboard engine and improve proof stress for an induction and radio noise, etc., by arranging an electronic parts unit having an injector driving control function for ignition trigger, ignition time and fuel injection on a base board and storing the unit in a case. SOLUTION: An electronic parts unit 601 having an injector driving control function for ignition trigger, ignition time and fuel injection is stored within a case 604 in a state that the components 602 of electronic parts are arranged on a base board 603, is held within the case 604 in a state the unit is covered by a resin filling part 605 formed by resin which is filled within the case 604 and is sealed with a cap 606. The unit 601 is disposed at a mounting base 610 fixed to the center part 22c between cylinder parts 22a and 22b of a cylinder main body 22 of an internal combustion engine via a mounting bracket 613 by making a surface including the base board 603 orthogonally cross with the main direction of vibration. Thus, an outboard engine is miniaturized. |
