"Old Wives Tale". Once properly dialed in an engines performance begins to degrade, not improve with time. It's a slow death with the well built motor and an untimely and expensive death with the poorly built motor.

Once I got mine broken and dialed in I picked up five mph on the gps and have not even pulled one valve cover off in three years off running hard, can you say, Spyder Prep Racing Engines.

Hey Ike thats what I would like to see. My dealer took the boat out to make sure everything was ok before delivery. He saw 77.6 MPH on GPS, I'm hopeing I can get it over 80.

I picked up 3-5 mph on my 28' Powerquest with a 502 Mag. How much was due to break-in and how much to better driving I can't say - I will say that the motor was MUCH more responsive in the mid-range once she had 20 or so hours on her. And contrary to what I had heard, the 502 never burned a drop of oil in the 2 years I owned the boat. Broke her in according the Merc manual and it worked for me.
