454 magnum mpi idle help
My 1997 454 Magnum mpi seems to be idling too fast. It is at 800 rpm. It was my understanding this should be around 600. I ordered the merc manual, but I am impatient. Maybe I am just paranoid but, this boat is new to me and I just want to be sure.
Thanks for any help.

I took a closer look at things. The distributor cap had a bolt broke off. It was raised off the base about 1/4" on one side. Replaced cap and rotor and everything is back to normal.
