IMG_2103.jpegHello, I just purchased a 2016 21SLX saltwater series with a 115 Yamaha SHO. Boat has the sport toon with strakes on only the sport toon, with a 13.5x15p solas stainless prop. I am running 5300-5400 wot with light load about 31-32mph. Reading online I am seeing that I need to get up around the 6000 rpm range so I ordered a Solas 13.5x13 prop. Just curious what other 21 sx owners with similar setup are running to see if I’m making the right move or should I keep my current prop.

I have the same boat but 2017 and the majority of us are running this prop and hub:

What RPM are you turning. I am reading that the 4 strokes have potential to get into a state of lugging which causes fuel to slip through rings into the oil system if you are not in the 6,000 rpm range at WOT. I am happy with my top speed and boat performance with the current solas 13.5x15 but concerned about the 5300-5400 rpm WOT causing issues.
 
I ran close to 6,000 rpm with my Yamaha F115 (non-vmax).
 
I get 6200 with 2 people onboard. This prop makes the boat jump/plain out faster and better control at slower speeds. Top speed is around 32. I typically cruise around at 4200 rpm's at ~20mph.. Here is another members post about them:
