So now that I have my sky turned in, here comes the next issues. What prop are you guys running in a 155? I’m running a 7/11 cut back. But I feel like it’s just spinning. Not much punch is givin.

What pump?
 
Stock 155
Im running a skat 6/12 cutback 5mm with my OE155 and that feels really close to me on a strictly flatwater, racegas setup. Play with your reduction nozzle bore if you haven't already. I will also say running the correct amount of timing with a good ignition is a night and day difference.

I agree. I think mine is just prop related now. When I first fire it up off the beach stand it takes off. But once the pump is loaded it just feels like the prop is spinning. It’s not cavitating, just not bottom end. The top end is there tho

have any videos of you jumping it or anything in the water?
 
It’s stock. I haven’t bored it out yet.
I would say the pump isn't letting the motor rev up off the bottom to full potential with a stock bore 155 nozzle. Bore it to around 88-90mm and it should be a huge difference. Tuning the pump takes some trial and error but its necessary to get the correct load on the pump.

Okay cool. I’ll try that before getting a new prop. Thanks for the input

I opened my pump to 89 and my steering nozzle to 92. Haven’t tried yet, it’s starting to get pretty cold here. So it’ll be weekend riding only for me now

I run a 1107 on 49s fs i change my return too a 110 return jet, made day and night difference. I Can Tune the ski now
I’ve been having dribbling issues even with new needle and seats on fs49 carbs. My return is much smaller than 110. What was your prev size return. How much did it lower the pressure ?

I had a vision!
Just got my personal wcf vision x finished with a et967+dual 46’s on a boyesend intake and a zeeltronic set up . I hit the start button and didn’t even have to adjust a screw . This thing is the hardest hitting stock stroke set up have ever had!!
the zeeltronic I think made a huge difference !
