Just picked up a 2016 21SL triton with 115 Yamaha and wonder if upgrading prop is a good idea for our time on the St Lawrence River.
Boat will be in the water end of March until November
Currently has a 13.5x15
Thanks!

You'd need to give us a little bit more info. Max rpm/mph what the motor Rpm is supposed to be. I don't have this hp but with additional information I'm sure somebody will chime in. My only suggestion would be to go to stainless for the most performance. 
 
I have not yet had the boat in the water so cannot give much more info at this time.


Based on 0 degrees F today, it may be a few more days before I get the boat in the water.......
 
Don't be scared..... what's a little frost bite! Just watch out for the icebergs!! 


I'd put the boat in the water and take some notes, speed, rpm, etc. once you have that base information then you can work from there. You could buy a similar unit in stainless but you might be wasting your money if you don't like what's on there.
