ABSTRACT:
Several embodiments of marine outboard drives including devices for protecting the unit in the event of tilting up more than a predetermined extent. The protection devices slow the engine when the outboard drive is tilted up more than the predetermined amount. This may be done by interrupting the spark, retarding the spark advance or closing a throttle. The invention is disclosed in combination with either an outboard motor having an underwater inlet for cooling the engine or an outboard drive portion of an inboard-outboard drive having a stabilizer for holding the outboard drive during a portion of its trim adjusted movement.
