Ive heard good things aobut what Mr Gadgets can do w Xr's

6 blade herings are the fastest prop for the Quattro, but harshest on drives. The cruise speed is approx. 6-8 mph faster than 5 blade merc's. (I have a pair of those to - 34's) Herings are perfect for inland waters where I run my OL, but in rough ocean stuff i can see it could be a receipt for disaster if you are pushing the boat. Ur currnet OL w/ 32 5 blades won't see 100mph, 5 blade - 34 labbed w/ the stock 600's may get you 100mph, light on fuel, 2 people, and hung out there in there salt water which will a couple mph vs. fresh water. If you want the fastest top end the 34p-6 blades w/ stock 600's is your setup. No need to test props they will work. If ur looking to upgrade to a 42, a set of 6 blades & a spare upper shouldn't phase ya Check out the attached write up Quatto w/ Merc 600 vs. Ilmore it has good info: http://www.mercuryracing.com/_media/...e--Boating.pdf
