Yes, you said that you were in Sweden. Sorry about that.If you can buy a complete engine, that would be easier and you would be certain that all the parts work together. However, you really won't...

Thanks, AnteP!Very interesting. Not much information on Shengqibao, but I saw some 4-wheelers with that name. It may actually have a re-branded Yamaha engine.Where are you located?

I've tested a couple units according to the procedure in the service manual and never got the results listed. However, the units worked fine in use. I think testing them with an ohmmeter is a waste...

Thanks, dfc1971!Can you post of picture of the corrosion? You replaced the manifold, exhaust pipe, and muffler? That was expensive!

I had a Cox .049 model airplane engine that had a rotary valve--60 years ago!

Welcome aboard, AnteP!Free PWCs are usually the most expensive ones!I'd love to see pictures, too! Pictures of everything. Hull, engine, gauges, jet pump, etc.

I doubt that a charger like that will generate much heat. The battery is kept fully charged almost all the time. A maintainer will let it discharge and recharge it periodically, but you probably...

You don't know how the steering nozzle works.

There should be a seal around the perimeter of both seat cushions.

Most of your play comes from the clearance between the steering nozzle and the jet stream.

I thought you were talking about the removable black bin. I do get a little water in the lower section, but a quick wipe with a paper towel solves that. When riding in rough water I get quite a bit...

No problem with removing them--until you flip it upside down!

Then it will instantly flood your 'Ski and possibly sink it.

I've tried adjusting the latch pin down lower to try to pull the door down tighter, but no luck.

If you find a solution let us know.

Does your storage bin have a drain plug? I haven't seen...

You may be using too much water pressure. Too much can flow backwards through the exhaust and back into the cylinders (at least this can happen on a Kawasaki, I'm guessing that the SeaDoo works in a...

I don't remember a cone-shaped spacer. Have you looked at the parts diagram?

Glad you got it running!

I hope that you tell Yamaha of your experience. I would also suggest that you give the dealer some 'free advertising' here!

The fuel pickup had a lot of problems and new ones are not available. I made a new one:

I will run the On and Reserve lines...

Heat & freezing, along with penetrating oil, may work.

Following that, use an end mill with a drill bushing to get the top of the broken bolt flat, then try a left-hand drill bit with a drill...

I don't know if the 260 had the upgraded jet pump or not. The 250 had problems with the impeller shaft moving and pushing against the crank and destroying the engine. Check for fore/aft movement of...

Thank relative speed. Which one is going faster while cranking? Which one is going faster while running?

I don't do facebook, either, but I was able to view it by clicking on 'Not Now' when it asked if I wanted to join. The music was hideous, but the Waverunner was interesting. I had trouble...

OK then, sitting for months without charging a battery will kill it. I guess it is 'a thing'. A brand new charged battery must be charged periodically or it will die. Dirty or loose battery cable...

If it sits for months without charging the battery, it can ruin the battery.

I thought I'd include a photo of the fuel tank. It's not like any other arrangement that I've seen. The thing in the middle of the tank is the pickup. It has two tubes, On and Reserve. If you...
