Hopefully you just tripped a circuit breaker. Your boat shouldn't have any fused switches up at by the driver.
After you double check the wiring on the switch and make sure it is indeed correctly wired. Look for a circuit panel like the one in the below photo. You just push the rubber button cover in to reset the circuit breakers.
If you did hear a pop then I would suggest really looking at the wiring and make sure none of it is burned.
