Need advice on props to use to get best performance. I have 1:5 ratio. What should my top mid and top speed. There is 28P signature on there now and mid is 55mph and WOT end 72. I have available 28P bravo's and a set of hydro that I dont know the pitch.

What motors and what RPM are you running? Also have the motors been touched?

They are stock 502 brand new. Didn't really see what the rpm where on mid to WOT.

OK, WHAT VERSION OF 502? hp500? Is it even a Merc motor?

Not HP stock 502 mercury.

If it was me I would try all the props you currently have, see what you get for results. Not your RPM and speed with all of them. You need to know where your peak HP is, I would think around 5300?
