Anyone know the correct way to break in a marine engine?
I've heard differing methods from the guy I bought the engine from & my mechanic friend.
I know in a auto you dont want to hold it at constant rpm to avoid getting flat spot on cam, but guy I bought engine from told me opposite for marine???

By the way, good to be back... I finally got that 425hp 454 for my '90 Sunsport rebuild and need to post pics from the stringer/floor build as well as all of the goodies that I have for her. I also have a beautiful black '86 Saltare for sale. Hit me up friends... LAKE SEASON IS JUST AROUND THE CORNER!!!!
