Congrats! I'm taking delivery of an F300 the day after tomorrow. I've read on the forums that they need to be run hard after the initial break in so they don't make oil.

I have two new 250's and I followed the manual. Pretty much what the dealer said. Page 56 Yamaha manual.

What is the break-in period for my new four-stroke Yamaha Outboard?
New engines require a period of break-in to allow the mating surfaces of moving parts to mate evenly. Correct break-in, as described in your Owner’s Manual, will help your outboard provide proper performance and longer engine life. Yamaha’s four-stroke engines have a 10-hour break-in period as follows:
FOUR STROKE OUTBOARDS
Interval Procedure
1st Hour Operate the engine at varying speeds up to 2000 rpms or approximately 1/2 throttle.
2nd Hour Increase the engine speed until the boat is on plane (but avoid full throttle operaton) and then back off on the throttle while keeping the boat at a planing speed.
Next 8 Hours Run the engine at any speed however avoid operating at full throttle for more than 5 minutes at a time.
After the 1st 10 Hours Operate the engine normally.
The break-in maintenance is at 20 hours. For the 10 hours after the break-in and before the service you can operate the engine normally.
