I read in a post on the props page that the Optimax's will not reach WOT until 20 hours, is this correct? Mine is a 2009 225 Optimax if that matters?
Thanks Don.

Incorrect.
There is NO PROGRAMMED RPM LIMITING FEATURE during break-in.
However, as with any internal combustion engine, as the engine components wear in, and "loosen up", they usually make better POWER, TORQUE, and perhaps a few more RPM's at 40-50 hours (as compared to fresh out of the box).
If you're not able to achieve the appropriate RPM range after 3-5 hours, something's not right.

We don't put many hours on our boats/motors up here in the north like some of the southern guys do just because we have about 1/2 the fishing year they do. I don't any any issues, was mostly concerned with choosing a prop and didn't want to have added RPM's because I did it to soon. I have probably 15-20 hours on my boat maybe.
Thanks.
You shouldn't have any problems propping that engine at this point. I wouldn't expect more than 50 RPM's difference as you move forward (based solely on wear-in).
