I have been using primium gas in this boat since I owned it. Is it required? If I go with lower octane what will the consequences be?

Your LQ9 requires gas with a minimum octane rating of 89. You are not gaining any performance or benefit to engine life by running premium gas. In fact you may actually get less performance from a higher octane gas as you don't get a complete fuel burn with the higher octane. This is right from the Indmar manual.
