Jasper Reman Powerhead Breakin ????

I pick my boat up Tuesday. What is the suggested break in for it? I've actually witnessed "idle around for ten minutes and then take off" and been told 10 hours of basically putzing constantly changing RPMs. So what do those way smarter than me think I should do? OX66 225.

ask the people who put it on for you, they are the ones who will know the answer and don't have to guess with a new power head.
