Default Prop question: swap results

Thanks again Gilly and Bush,


Ran my 115 E-TEC with a 13 X 15 SST yesterday vs. the 15 Viper that came with the engine...both as a singleton and with 5 grown adults (and full 45 gals of fuel).
Results were:
NO problem spinning up to 5500 rpm at WOT
Faster out of the hole
Easier steering at top bend (I had another thread on this steering issue)
Engine clearly not laboring as the Viper was to keep it at 4800 rpm's
Only thing I am giving up is 2 to 3 knots at top end. Was able to do 26.2 kts GPS vs 28.5 kts (with Viper)...which is fine by me.

Soooo....unless there are other thoughts, looks like I will stay with the SST.

Thanks!
