There is geometry in the fiberglass of the jetski hull leading into the intake so your best bet is the cut a large hole in your boat leave part of the fiberglass hanging below the boat that whatever he talking about would never work lol that's gonna push the intake up and out if the water
These videos are posted "behind schedule". The boat had been in the water the entire 2019 season several dozen trips. It yielded 45mph. I understand what your saying about the factory intake design, but if I glued any of the factory fiberglass into this design, it would have been destroyed. We took a boulder hit when the river was chock full of leaves and couldnt keep the pump from clogging, leaving us with only a semi plane. Im definitely glad my intake is nothing but Aluminum lol, because this repair im making now is a cake walk, had I done a glass insert from the ski, man id be back on the drawing board! As far as the intake being pushed out of the water, this boat handled the ocean/bay/rough lakes without cavitation, so as far as the forum reports go, im one of the builds that never had to deal with cavitation problems, due to my intake water dynamics. Stay tuned and thanks for watching, I keep the vids coming, just waaay behind shcedule.
So does the spoon have to be directly in front of the intake or could theoretically if I had an outboard jet, could I put a spoon on the back of my boat and still have it direct water to an outboard jet with a jet foot?
That was to allow it to taper out faster, had to cut it to blend the angle into the hull. I Cut that spoon off the boat completely, dont do a spoon with aluminum its too aggressive. What ive been running for 2 years now is a spoon molded out of plain bondo. very subtle, only sticks out about 1" in height versus that old aluminum one was more like 4" high and was way too much. If your doing an inboard jet, make your spoon with bondo.
I never ran this without a spoon so I cannot tell you precisely. What I will say is that I have had it in the bay/ocean many times as well as rough lakes with very limited cavitation, more like how youd expect a jetski to behave. The worst situation for this boats cavitation is when your running with a STRONG tail wind in chop, but that comes with all jet designs.
Well since I hadnt tried it out before the spoon, I dont know what kind of difference it makes. But in 3' waves on a big lake, it surprised me how well it was able to fight cavitation. The only times it cavitates bad is going through white water rapids and going WITH the direction of the wind chop on rough waters. So all in all I was surprised how little it cavitates. Also, Just last week we smashed a rock and crushed the spoon completely lol. Many hours and miles so far this season and a series of events lead to the hit. Flash downpour filled the river with leaves, pump would clog every 20secs, got dark on us, couldnt fully plane due to clogged pump and BAM hit a submerged stone in the dark (normally have 0 issues with that area). I patched the leak and it still runs full speed on flat water with a massive dent lol.

It works great actually. See for yourself what a spoon does to the alter direction of flow using your kitchen sink.

"on the boaut". Found the Canadian!
May I ask why the split down the middle at the front of the spoon? Is that necessary or can it be solid across?

how's it running March 2020
Its going back on the water end of this week. Setup works out great. Ill have new videos coming soon.
Did it help considerably with cavitation?

What was the outcome? Did it make a good difference?
