Abstract
An arrangement for insuring that an internal combustion engine of an outboard motor will operate efficiently under all trim adjusted conditions of the outboard motor. The trim angle is sensed and an engine system such as the timing is adjusted to provide good running in response to the trim condition. Additionally, an embodiment is disclosed wherein the ignition timing is also adjusted during initial starting so as to provide adjustment of the ignition in response to both the starting condition and the trim condition.
