Thanks @fastgtfairlane and @WFO Speedracer I have rebuilt the Bendix on the Super Jet type starters a couple of times, but never the motor. I'll be back . . .

1993 550x with reed engine. Interstate Battery, 12.79 DCV Starter switch causes (the starter solenoid?) to click/clunk, but no cranking by the starter whatsoever - not even an attempt to spin the engine. No humming, no sound, no nothing. 12.79 DCV at the starter solenoid-in post. 0 DCV at...

Just a thought. I disconnect and bypass all of the On-Reserve-Off fuel lines in our skis. And just leave the selector switch there but non-functional. I also install an internal fill. Because it allows me to look directly into the tank. Which can be helpful for many things including when...

The FishStix look cool! If you want to try a slightly more expensive version, Wax has these which I put on my FX-1 and everyone and I mean everyone likes how they improve carving and reduce sliding -- when you want to slide you simply do not lean the tail of the ski as much ...

@Myself I know that you are one of the professionals on this forum. Can we peel the onion a little farther on this matter? If you take a look at the Super BN 44 Diagram on the left and the Super BN 38 on the right, you will notice that the SBN44 does not have grooves for the Rubber Oring to...

Good eye @Myself !!!!!!!!!!! I see the difference now. Is this the correct one?

@Myself Thank you for your post. I am looking at my photos above. Is the Diaphragm wrong? Or is the round skeletonized gasket wrong? Or both. I believe it is a stock Yamaha SBN44.

I did not clean out the carb ports with carb cleaner yet for the following reason. I have four filters/screens protecting the ports in the carb: 1. In tank pick up screen; 2. Aftermarket triangular In line fuel filter; 3. OEM Yamaha fuel filter on the inside lip of the engine compartment...

@Penguin How is your troubleshooting going? My screen was perfectly clean. @Big Kahuna did you once have a fuel starvation at WOT due to a screwed up diaphragm? Could the bloated diaphragm be the problem? I replaced it but haven't ridden the ski yet. Photos below: Look at the rust on...

^^^ Brilliant! Will do and will report back.

One thing I haven't checked yet is the Check Valve which when working fully permits the same volume of air to enter the fuel tank to compensate for the vacuum which would otherwise be created by the equal volume of fuel being sucked out of the fuel tank by the vacuum created by the carburetor's...

Update: Still stalls at WOT. So will remove the carb and look for clogging in screen, fuel metering, etc.

^^^ Hey @Roseand would you post up a video clip of part of your performance? Your suit looks awesome! It reminds me of Teton Gravity's fantastic movie Fire on the Mountain

I have this on the fuel pickup in my FX1: Yesterday, the ski would die at WOT racing my wife. FX1Dave told me it was likely fuel delivery starvation at WOT. I started troubleshooting this morning from the tank to the carb and noticed dirt in the tank. The fuel pickup screen also seemed...

Holy crap! I am grateful that I started trouble shooting at the fuel tank. I have a load of crap in the tank. The a Blowsion fuel filter/screen at the end of the fuel pickup tube is clogged. I do have another filter inline on the top of the fuel tank as well as the oem fuel filter on the...

I am the least knowledgeable person on the forum, but yesterday, riding for the first time this season (dude I am so sore today), my FX1 would die at full throttle racing my wife. Fx1Dave said it was likely a lack of adequate fuel delivery at full throttle. So, I am now taking the carb out to...

Yes, that is crazy. An unlicensed parent could rent a 70mph sit down jet ski and lend it to his 8 yr. old kid and neither would have been required to have taken and passed the Boater I.D. Card regardless of whether or not they have ever driven any motorized vessel including a jet ski before...

I learned all I know about boating from this man:

It is a $250 fine if you operate an engine driven vessel (e.g., a jet ski) without a California Boater I.D. Card. And I saw two State Parks rangers wearing smokey the bear campaign hats with two beautiful brand new white SUV's with big law enforcement stars on the doors writing a guy a ticket...
