Melrna hit all the obvious points, pink jobs notwithstanding.
The only other thing I'd mention is that 3100 rpm sounds a bit high for that engine for continuous operation. I know it's within the rated rpms, but subject to all the caveats relating to prop pitch and size, we have the same unit in our boat and we cruise in the 2700-2800 range. We occassionally will do brief bursts into the low 3000s during docking manoeuvres, etc, but the engine just sounds like it's really working hard at those rpms so we don't stay there long. Maybe consider running at lower cruise rpms, i.e. < 3000.
Now about those cinnamon rolls....
