Have a aqua jet boat with ss1 motor and 42mm prop (water cooled motor and speed controler) looking for suggestions for a little more prop -- poss more speed
Scott I would not suggest the 645 or 447, they are both to large in diameter to fit under the stock rudder bracket. So you would have to lift it causing handling problems. I would try a x642 or a s220 Prather. The Prather is a tad in diameter(about 44mm) but can be taken down a 1mm.
