Backie chan first time flips ever

I would say I have the boat tuned about 80% I can tell there's still some power hidden somewhere in her lol. Landed 2 flatwater and 4 boat wakes tried about 12-15 total so I guess that's not bad for a first timer lol. Ill try and load video tomorrow



Nice man!

I am officially trying my first FW backflip on Sunday so I will soaking in all the tips

So that's the idea? I know someone has done this any first hand experience and can you tell a difference after you did the boreing?


There can be huge differences with even 1.5 mm bore size difference in the nozzle. Generally speaking, water is incompressible and the reduction nozzle really increases water pressure. Smaller diameter means higher pressure, larger means lower pressure. If the impeller is too steep then the engine cannot turn it enough to increase the pressure that much. Bore up the reduction nozzle, pressure goes down, the engine can cope.

Some guys are pushing those pumps with smaller displacements. It's all in the prop pitch and nozzle diameter. Call the guys at skat or impros and talk to them directly. Prop pitch is gonna be crazy low to get it "on the pipe" like it needs to be to hit.
 
My motor feels like its not winding up fast enough. I bored reduction to 90 and it got better. I'm going to get a new prop 6/13 and hopefully does the trick for full wind up. Smaller motor and big pump can be done but the tuning window shrinks tremendously unfortunately
