I would second the comments about propeller vents. If you propeller has vents in the hub near the leading edges of the blades then block them up with some plastic plugs - about 50p each from your friendly Mercury dealer.
I found that my Laser 2 performed much better once plugged.
The Vengence seemed to cavitate a lot - but no holes to plug.
