Rebuild break in

[tweekster]

1992-50 hp-3 cylinder I'm rebuilding, all fresh, how do I do a proper break in on the motor when finished? Any first start up advice? How about the hours after start up in the water? Any different oil mixes, it has oil injection?
Thanks
Ron

I'd use double the amount of pre-mix oil and the normal 10 hour break-in as specified in the manual....just like a new motor.
