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?

A Ribcraft 4.8 (assuming that is what you have) goes well with a Mariner 60. I used to have one with a 60-stroke, and I used to have access to one with a 60 4-stroke. Both went at about the same speed (34 knots if I recall). Since they are both Mariners swapping will be nice and easy - just unplug everything, take one off, put the new one on and plug it all back in again. If it's not going to cost you too much I would give it a go.
