Dropped the boat in the water yesterday and even though the engine ran without issue I couldn't help but feel that it was "down" on power.

It is receiving about twice as much oil as it should right now as I premixed the fuel tank and the oil tank is delivering as well. Would that reduce power?

What could cause a reduction in power? Spark plugs have not been replaced this season yet as I wanted to get through the current tank of fuel first.

Maybe its just in my head. Fell like I have to run it at 4K to get the performance I used to get at 3200K. Any thoughts?

Could a full tank of fuel from the fall cause a feeling of less power? Octane does have a shelf life right?
