Its a Quicksilver part number 48 11078 440 25P, I currently run a high five with 23p, looking for more speed, at WOT I run 53mph at 6100RPM with the high five, I am looking for more speed and just to have an extra prop is a good idea.

So what can you tell me about this quicksilver 48 11078 440 25P

The motor is a 87 150, black max xr2

Thanks

"...at WOT I run 53mph at 6100RPM ".

My book says that the recommended WOT for the 1987 Black Max 150 xr2 should be 5000 - 5600. You might be over-revving it (not good). Increasing to a 25p should reduce your RPM by (approx) 400, putting you closer into range. What is the prop diameter? Something in the neighborhood of a 15 (or 15 1/2) x 25 might be what you are looking for.
