I don't have a tech book here, but you can't go wrong with 1/2 to 3/4 throtal varing the rpm every<br />few minets. Just don't run it at any certian speed for a long time, like trolling for hrs.<br />After 12 gals of gas you can run it mostly like you want to, Just not wot for hrs at a time or trolling either. When you have 20 hrs on it you can run it like you want to. The worst thing you<br />can do is let it idle in neutral very long when it is new or when it is cold.<br />...have fun...corm

Xenos,<br /><br />Straight out of my Merc manual for a 2002 EFI 60HP 4-stroke = <br /><br />1) For the first hour of operation, run the engine at varied throttle settings not exceeding 3500 rpm's, or at approximately half throttle.<br /><br />2) For the second hour of operation, run the engine at varied throttle settings up to 4500 RPM or at thrree-quarter throttle, and during this period of time, run it at full throttle for approximately one minute every 10 minutes.<br /><br />3) For the next eight hours of operation, avoid continuous operation at full throttle from more than 5 minutes at a time.<br /><br />I am a TOTAL motor moron, so I'm NOT trying to tell you anything, just reading it out of my manual.<br /><br />Best of luck.

Bought a new '02 90 hp Merc 4-stroke in Sept. and BeBogy is correct on break in info. Dealer told me a biggy is not to let it idle for long periods during break-in.
