Dennis - I'm struggling to think of a rib that won't be minimum of 4.8m if your planning to use your Mercury 75hp. Sure you can go smaller, but the engine will exceed the hull and transom rating and all the consequences of over-powering, etc.
The 4.8m I use with my brother, mainly for fishing and we've been out in some fairly rough stuff. I can't speak highly enough of its sea-keeping abilities, but once you're on the water, then the boat doesn't feel so big.
It's no lightweight granted. It can be towed on a 750kg unbraked trailer, but unless you can launch and retrieve yourself on a slip then I'd look at something smaller. We've retrieved on a low tide from the beach with ropes and it's definitely a 2-man job.
My advice for what it's worth is to identify a budget early on then look at size. Also consider selling the Mercury engine rather than trying to find the boat to match it. Most second hand boats will come with an engine, and there's always a demand for mid-sized 2-strokes in decent condition.
