1st off you need to go on Yamaha outboard website and there you can find the WOT rpm range, than you need to know your current WOT rpm now with current prop, than you also need to know what prop you have now. [your speed also would be great]

Once you find all this than you can see if you are having problems, maybe its running ok and you think its not ??.

Here is a link to a place that sells props, they show your rpm WOT range at 4500-5500, however I am not sure of your year.
