Boat Break-in & Running Q's

[Dad sold the C * C]

Just went thru the break in of the 150 4 stroke Merc this summer. It's a 20 hour break in with varying the RPM, the Manuel says to run it at WOT during this period but for 2 minutes or less at a time. Apparently this engine will beep at you if you do something it doesn't like during break in..

It was running real nice just before I put it to bed for the winter.
