Use DFI.As for water temp that is fine just make sure the engine temp is up before taking off. Idle for about 5 mins to reach 120 degrees.

Dealer is right Opti-DFI.

Your dealer is CORRECT- see the following post:

Although it would be PREFERABLE to run in 60+ degree water temps... proper break-in can be accomplished at cooler water temps.

HIGHLY recommend you have a Smartcraft Instrument... set to read engine temp.

See your owner's manual (Break-In Instructions).... or the following post:
