14/19r or 15/20r
Wonder what prop I should throw in this year. I have both. My 14/19 is in a little better shape then my 15/20 but that obviously don't mean nothing when it comes to what belongs.
top loader intake grate
r&d stearing nozzle
215 stock ecu
water box mod
just a little info if someone is running anything close to that, what prop are you running ?
Thanks for the help in advance

14/19 with a stock ecu and If you reflash 15/20. If you really want to wake your ski up you should get a reflashed ecu and retainers.

You need a 15/20 like I've stated many times before to people with this setup You will be 1 mph fast with it over an 14/19 as well
thats 14/19 sure works but it's past its potential and basically is spinning. The root angle on the 15/20 is different and is what's needed for this setup

I had an 05 (old ski below) with pretty close to the mods you have and ran a 15/20R.

From my personal experience on my rxp with similar mods, 14/19 with the stock ecu worked better than the 15/20 and once I went with a Lescooke 8650 tune and retainers the 14/19 was spinning, the 15/20 with some tweaking on my old set up worked awesome. Climate, altitude etc will play a part in your skis performance. Greenbullet knows his skis so I'd definitely take his advice especially if your going to continue modding it.

due to climate changes that 14/19 will slam the limiter easy. The 15/20 is a solid base and possibly bend 1-2 mm
also he is using stock Ecu at 8100. I've had 3 props at one time lol different bends. All different results. 15/20 took the win. Then it all went down hill with a big charger now I have a 15/24 at 8800 lol

Before I put the ski to bed for the winter I was spinning 8700-8800 with a 15/23-24 in cold air. If I pull bend out and spin 8900-9k I'll be fast but this is still on a bone stock bottom end! Don't want to risk it Won't rebuild until I need to. If it pops it's the chance we all take for modding skis

Ran this set up and used a 15/20r
