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

It was same level of fuel also mine is 3 blade

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

yes... you're right!
