Asking price is high if you ask me.
I have an 01' R73 with an Evinrude 115 (so pretty close match to this), and it does about 43 top speed. 45 with the wind at your back maybe. Plenty fast for a 17.5' boat. I bought mine in 08' for $10,000 and change and it was in pristine condition.
That said...........I wish I'd bought a bigger boat especially with whats on the markets today. You can get more for that money if you're not set on a Ranger. Don't get me wrong, I love Ranger boats but if I could do it over I might have opted for a bigger boat, different brand at the same value. just my .02
