Hey gang

I already posted a question in the prop section but I thought I would check hear too. I have a '78 OMC 120 with 400 stringer. The boat had come with a rebiult prop of a different pitch. I put it on and getting 4000rpm at WOT. I like how this prop works but can my engine handle this kind of RPM?
