How many hrs should I put on a rebuilt motor before I change the oil?

I have 3 hrs on it now.I'm thinking maybe 10....What do you guys think?

Break-in for a new boat engine was 10 hours (maybe it still is?)
What does the rebuilder recommend?

depends, I will run the engine at 2500rpm for 15 minutes, shut it down and change the oil

I would use the Indmar break in procedure as a baseline and put 10+ hours on it. Change the oil and let 'er rip!!

I think it depends on if you used a bunch of prelube in the build process. I would have changed it after an hour and then again after 3-5. But people often say I am a belt and suspenders kinda guy...

Oil is still relatively cheap. If nothing else I'd drop the oil now, keep the filter and then start on regular oil/filter change specifications.

I still change the oil on my new cars after a 1000 miles then start them on a 5000 oil/filter/tire rotation schedule. It's worked with the cars. Unfortunately I've only purchased used boats so that break in time is never mine to gauge. The closest I came was with a 03 X3 with 75 hours.
