I can only offer what I experienced when renting a Grizzly 1860 last year. It was equipped with a Merc 40 4-stroke. With just the wife and I in it (no gear, live well empty) it would plane out just so-so. Not a speed demon by any means. Therefore, I could extrapolate that either the 70 or 75 with a 1754 should make it almost fly.
