Breaking in new engine day three

I have finished the break in period… I took the boat out again with Patty and Jeff after running it for a while at the dock to finish up the break in period. I don’t know if something is wrong with the engine or what but it doesnt perform as strongly as my old 4hp 2 stroke. It also has a lot of vibration. I have talked with tohatsu and am going to take it into the local service center and let them take a look at it. The guy at tohatsu said if it isn’t getting up to the top end rpms it is supposed to be then it could be the timing advance having problems in the electronic ignition. They have seen this before. Or that I possibly need to get a lower pitched prop. The one on there is a 7.7 inch 8 pitch prop. I can go down all the way to a 7.9 inch prop with a 6 pitch.
here is a video of the engine running at the dock.
