  If your Monterey boat engine won't crank, several factors could be at play. Start by checking the connection of the engine stop switch and ensure the throttle/shift control is in neutral. Inspect the main circuit breaker and reset it if necessary. Clean any corrosion from the battery terminals and verify the battery isn't weak; recharge or replace it if needed. Finally, inspect and secure battery wiring connections.
