Do as Nos says , and if if the engine is new you should be takin it a bit easy on it
They say run new engine in on 25-1 , having just done that with a new tohatsu I would say its not necessary on a light boat .
have you checked and cleaned the plugs ?
If your engine has oiled a plug and is running on 2 cyls , believe it or not you may not notice untill you try and give it full throttle and then it just feels down on power as if its a 30 , it doesn't run rough at all . That caut me out first time , and having recently run my toghatsu in by the book it does oil a plug almost every time you go out for a while ,always one of the two lower cyls .
Forget the rev limiter that only stops it over revving , and you are not reaching that by the sounds of it .
