Yamaha F70 4-stroke outboard 2013 breaking it in.

this is the new 70hp 4-stroke yamaha in its first few hours before the first 10 hour first oil change after the brake in.
the first 10 hours with every outboard you have to work it on all of the rpm range.
starting slowly to increase rpm with every hour. this is about the fifth hour of its life.
in the following video i will try to reach top rpm potential for about 2 minutes so the springs in the engine can settle in on all rpm like i mentioned above.
unfortunately, with the very first size of propeller that the mechanic thought it would reach above the 6000 rpm range it was wrong. it only reached 5000 rpm.
after the next video we drop down from 17 pitch to 14 and we got almost 6100 rpm witch i thing is close enough.
