Not knowing how much ">4m" your boat is, you will notice a difference, just how big a difference will, as usual, depend on a dozen different things.
For what it;s worth, that's a 20% increase in power. I went form a 25 to a 30 on my old SR4 - a similar jump - and although it wasn't spectacularly different, stuff like hole shot was a bit livelier, and I got another 4 knots on my top speed. Made naff all difference at normal cruise.
As you have double the HP there, and assuming your boat is 4-4.5m, you'll get a bigger "step change" than I did.
One thing to check - I assume your transom is rated for at least 60?
