Re: tohatsu prop
Remember to always use the model when referring to service issues with a Tohatsu/Nissan motor. You likely have model MFS8A3. Should have come with a 3-blade 7-pitch prop.
The prop selector guide is online at

Depending on how light your boat is, a 9 pitch may get you some more top speed.
As usual, more pitch=higher top speed, less pitch=more hole shot. Too much pitch will prevent you from achieving correct WOT RPM. Too little may cause you to exceed the correct WOT RPM. In the case of the 8/9.8, the rev limiter would then engage, hopefully before you throw a connecting rod through the block.
