What rpms/speed are you running now? Any mods?

[Mohsen]

4" air filter
IMUK
Catch can
Maptune stage two imuk 8500 plus

Untouch prop 7800 rpm then I took it to the garage after repitch the prop 8200 rpm (don't know numbers of the pitch)

They told me 8200 rpm to be safe because I don't have retainer

Max speed 77 on dash

id say 8400ish is when I'd start being concerned, but retainers are easy to install if you are concerned. Not sure what the limit to bending the stock prop is but keep in mind you are changing the diameter so eventually you'd want to have it machined back down. You are also changing the distance of the impeller blades to the stator which again becomes less ideal. I'd probably live with it or maybe think about a cam to get a few hundred more rpm. I'd probably give the new 13/16 solas 3 blade a try and see where that puts you.

13/18 SXX will get you a few more RPMs... just check the pitch of the SXX prop before you install it.. they can be off a little.
and be prepared to de-pitch the Solas SXX a little to fine tune it to your riding conditions.

I de-pitched my SXX 1mm and in cooler weather I'm doing 80mph at 8538 RPM's.
weather here in NJ now is high 80's to low 90's and best I can do is 77/78 mph at 8300 rpm.

That's why I recommend starting with the 13/16. He's already running a depitched stock prop to get to 8200.

So should I give Solas 13/16 sxx a try or is it better to go with 14/19 honestIy don't have any experience on the numbers and don't know which one will work good for my condition

If dinomite says 13/16 I'd listen to him, he knows his stuff and never steers anyone wrong[emoji1]

14/19 would be more pitch(steeper) than a 13/18 and way steeper than a 13/16.

He's already had to take pitch out of the stock prop to get 400 RPM and he's in riding in conditions way hotter than you or even I am in Florida that's why I recommend starting with the 13/16. He might even need to take pitch out of that one.

Thank you guys for the help

Do I need to install r&d pump seal or just stay with oem one ??

The OEM one is fine as long as you don't pinch it when installing it and as long as it's in perfect condition when you pull the pump. That being said if you are ordering stuff, I'd go ahead and get the R&D one. It's a no brainer for $38. You want the one for the RXP (where the pump mounts to the hull) . Takes the worry out every time you remove/install your pump that you are going to have a good seal. Either way I'd spray a bunch of window cleaner on the seal and pump shoe when installing the pump to make it slip in easier.

Update on my ski I tried solas 13/16 untouched prop rpm was 8400-8500 speed 78 on dash half tank of fuel
I didn't notes any different in acceleration and no gain in top speed so I might go back to oem one I will add 400 rpm on it

Weather was 112 F water temp 88 F

I no you said at 8200 you ran 77 on the dash was that with a full tank like you just ran? If so you are running 2-300 more rpm for one mph gain which makes sense in all my testing I’ve seen a 4 blade will always run more top speed rpm to rpm
