Well the original jet ski intake is not up to the task. I figured it would be a weak link but thought I would give it a try before just ripping it out.

Still have not decided whether to go with a cast intake with nice heavy duty grate or fabricate one here. Looks like it can be done several ways. I played around a little yesterday on solidworks with the Sheetmetal tool (which I rarely use) and I looks like it should be doable.

Hit a few things pretty hard, made a big groove in the rear inlet lip. Broke some of the inlet bars loose. Don't think it all happened at the same time but got sorta rough with it.

The ship runs clean on about 2 inches of water at about 30+ MPH but somewhere at around 2 to 1.5 inches water it stops real quick. Beached it several times while ripping along. You defiantly want to be sorta braced up.

Toying with the idea of fabricating the intake myself. The hardest part looks to be making a heavy duty stomp grate.
In the end I may still just order a cast setup with grate complete from a vendor.

It looks like the intake repair will constitute quite a bit of renovation so will probably turn into a complete overhaul of the ship. Considering UHMW sheeting on the bottom like some of the mini jets run up north. Question is, will UHMW sheet help any with sliding on sand? Any experience?

I love the Bi plane.
I dated a chick that said she was Bi, I thought that is was going to be awesome! But turned out she was Bi polar.

Well, the intake is removed. Gutting the hull to bare metal and stripping the entire interior out. New cast intake is on the way with heavy duty stomp grate.

Playing some with interior layout. Not much room in the little thing. Rear seats will end up pretty narrow but my girls are little. They should be able to ride quite a few years. If I were building from scratch would consider making a contoured bench for the front but in this case probably move ahead with the current seats. IMG_20190715_183117.jpg

Any of you jet boaters here happen to have access to the technical spline information on a Yamaha wave venture 1100 impeller shaft? Caliper measurements show 0.700" or 17.78mm major diameter with 16 spline teeth. I have been digging for a while and so-far have not been able to find a spline standard to match the shaft.

When installing the new pump inlet the plan is to move the engine back requiring a shorter impeller shaft. I have a machinist that has the capabilities of cutting the shaft and re splining the end but would need to locate the geometric data for him.
