Nearly all jetskis are direct-drive without gear box. Most 4-stroke Yamahas (MR1 engine) have a reduction gear box.
Jet-pumps start being useless at around 7500 rpm.

The particular 1100 that is pictured above puts out about 110-120 HP, though torque is a much more meaningful number in this application.
The strongest stock Jetski engine made today is a Kawasaki 1498cc 4-stroke, super-charged and intercooled. It's sitting at 310 HP.

The strongest stock 2-stroke made was likely the Yamaha 1200R, a triple-cylinder pushing about 150 HP.

The most impressive 2-strokes in Jetskis are performance engines for standups. Current pants-creamer is the XS1400R, a 2-cylinder, 2-stroke 1400cc engine.

It makes what's shown in this video possible, and keep in mind that it showcases only the older 1200cc engine.

Coming back around to stupidly located bolts and fasteners my father has an entire toolbox full of cheap wrenches that he hand-bent into all forms of absurd shapes with an oxyacetylene torch for working on tractors and bulldozers. Sometimes on those machines it seemed like the only thing the John Deere engineers cared about were the engine mounts and the final drive locations, everything else was a matter of seing how close you could fit things to solid steel panels. There were all sorts of bolts that were only accessible by either tearing down the entire bulldozer or with a wrench with a dog-leg 3" from the head followed by a 45 degree run to clear another part.

That reminds me of a problem we solved at work. On the CFM56-5A engine, there is a turbine clearance control valve, called the HPTCC. It bleeds air from the compressor to shrink the case around the turbine for efficiency.

Sadly, being buried on the case since it bleeds right off, you had these four bolts which heat soaked and cooled, so they were stuck in good, always had to use anti-seize to get em out. But you had no direct access to remove and install the bolts. Eventually we had an intern jig up a torque wrench extension and do all the calculations cause the CFM tool was too expensive.

located pretty much dead center in the middle, opposite side by its just as spaghetti there as it is here.

drat thing also had a gasket that would leak and set of engine fire warning. yay those were fun to deal with.

Each engine has two hydraulic pumps a primary, and a backup, and the garlock seals on the primary pump failed in a rather spectacular fashion, which let the pump dump the entire contents of the #3 hydraulic system into the engine main gearbox.

Kicker A: The flight crew saw the engine oil temp go up, but didn't want to declare an emergency or do the paperwork that a shutdown would have called for, so they just yanked it back to flight idle, and flew it another three hours home. :cripes:

Kicker B: GE technical services had us change the oil, run it for half an hour, change the oil again, and then test fly it, and signed it off, despite three hours of operation with hydraulic fluid for oil. :catstare:

Ordinarily I'd be all "drat, that is a :black101:

But for something that sees 40k' on a regular basis, uh... :stonklol:

I would at least want to tear it down and inspect it for wear.

This happened in Bergen, Norway earlier this month.

Crane was lifting the container down from the roof. It snapped, the thing fell four floors and hit two occupied cars. Drivers were stuck for a while but came away with minor injuries. This is right next to the best wine shop in town, so there but for the grace of God...

By being an unconventional thinker, and towing it on a flatbed through, rather than under, a bridge or overpass.

VVV: Removing the valve stem, or (more often) the valve body with sidecutters. Unless the tyre is still actively deforming, it won't explode unless you do something foolish to it.
