Hello, my name is***** will assist you.

Code 17 is for the MAP sensor on the engine. This could be a torn boot on the sensor, a failed sensor, or an issue with the throttle body. You would need to inspect the intake for air air leaks.

Code 22 is the warning horn output, meaning that the horn in the boat is not working. Most of the time it is just a failed alarm horn. It just plugs into the harness and is very easy to replace.

Please let me know if you have any questions.
