depends on length/width/hull ype/and total normal weight load but heres and example 75 16 ft. sangstercraft /deep v hull weighing about 1800 pounds total incl. motor gear etc. i use a 12pitch prop it does 46 k/hr at mid trim and 51 k/hr at max trim ( roughly 22-26mph) if you are heavier or longer you will want an 11 or even a 10 pitch . best advice though is have tachometer installed so you can verify you are turning max rpm's at w.o.t . a motor running at its full potential will be healthier than one running outside that range usually 5000 - 5500 rpm

How do you flush out a 9.9hp mercury outboard?

The 9.9 hp Mercury outboard requires a special flusher, and removal of the propeller is suggested for ease of installation. You can use a regular flusher if you position it just right, (the water pick-up is located underneath the anti-ventilation plate, above the prop), but I find it easier to use a barrel or waste can.

I have a 60 hp mercury outboard The bottom tip of the skeg was broken off about 2 to 2 12 It does not seem to be effecting handling or performance is it necessary to try to fix it?

It's good to repair it as it protects your lower unit and prop. However it won't affect handling. It is not a rudder, it is a prop protector.
