Is eBay seller full of it?

[kilgorekb]

I order a new fuel gauge from an eBay seller. My boat is 1999 Challenger 1800. I looked up the part # and got 204470319. I searched for that part and found it was superseded by 204470963. I found 204470963 on eBay and bought it. The gauge reads 1/8 tank when in actuality I have 1/2 tank. I measured the resistance at the gauge and got ~50 ohm, which I crossed referenced with my shop manual and found that reading was consistent with 1/2 tank. I notified the seller and this is his response,

"Hey I don't what to come off as a prick but if u did the research and looked up the part number for your year and model seadoo u would have gotten the part number 204470319 not the part number gauge I had posted, which will not work due to the different size tank and different ohm values in conjunction with its specific model fuel system, sorry for any inconvenience

-mgncv121"

Is he correct? If a part is superseded, I would just assume that it's 100% comparable to the old part. Or is he full of it?

Can't comment on the seller but...

The gas gauge on just about every sea doo boat that I have been around reads about 1/4 tank off. My 99 challenger 1800 currently has 1/2 tank and the gauge reads 1/8 tank. It is not a big deal to me, but for some it is.

I think if you remove the plastic float from the baffle it should have two magnets. Remove the top magnet and it should read more accurate...so I have been told.

That's a lot of play...literally haha. About an hour difference at WOT. I believe the gauge may be off from the factory, but 3/8 tank off?? More will have to chime in before I accept that (no offense.)

I can't remember if the one in my Speedster was close or not--it stopped working years ago. I've been to lazy to fix it. Just as easy for me to pull off to and look at the tank. It never bothered me. You should have reserve too. Once you hit reserve your the beeper should scream at you and the orange light on your toggle switch will light up if it's like my Speedster. I've only ever hit Reserve twice sine 99.

Turn the baffle upside down and see what the gauge reads?

I don't see how the seller can be responsible for a cross-reference mis-match. If the gauge doesn't work as it should then maybe?

I wasn't aware seadoo used fuel gauges of different calibration but I guess it's possible.

My gauge seems to read a bit higher than the amount of fuel in my tank, so I must've pushed the baffle fully into the tank or perhaps too far? This boat runs out of fuel as the gauge hits "E" though, not much remaining on reserve, barely made it back, I think it was sputtering and died as I pulled up to my dock.

my 1997 challenger 1800 gas gauge reads about 1/4 tank lower than it actually is.

Read this thread and ask @rebuildseadoobaffles if he knows a solution.

It's your call and your boat!!

Been my experience that gauges either work or they don't.
No calibration...just push the baffle down further and remove the top magnet. Believe it if you want.
I think, I will now exercise my right to shut up!!

 

[Sportster-2001-951C-Stock]

I agree with the idea of removing one of the magnets, all's fair in love and war and if it changes the calibration enough in the right direction to make the reading reflect reality then I see nothing wrong with that.

I can tell you my experience with customers boats is they'd like for the gauge to read empty before the boat runs out of fuel.

All 2 stroke seadoo baffles (except DI models) read 0-90 ohms, 90 being empty, 0 being full, 50 ohms should register a tad over half or 5/8 of a tank on the gauge. Im willing to bet something is messed up with the gauge or you have the incorrect one. 1/4 tank of fuel should read 22-28 ohms on the baffle. Removing one of the magnets on the new style baffle will cause dead spots when the one magnet is between the sensors on the board of the baffle. The 95 and older baffles had one magnet. Have you filled it up all the way with gas? does it read 3/4 tank on the gauge with 88-90 ohms present at the baffle? Or as stated take the baffle out and turn it upside down to simulate a full tank and read it that way.

You may also want to check to see if the Baffle is completely pushed into the tank. If it has been removed maybe it is not sitting at full depth in the tank.

I haven't tried it with a full tank. Either way the gauge should be reading ~1/2 tank since I measure 50 Ohm at the gauge.. And because my shop manual says 50 Ohm is equal to ~1/2 tank. I didn't mean for this thread to turn into a troubleshooting thread. I was just interested if superseded gauges were the same as the indicated replacements, because if different, this would be the only bonafide explanation as to why my new gauge is off... seeing as how the sending unit checks out. Anyway, I'm gonna try another gauge and when I report it is also 1/4 tank off, you can all say "Ha Ha I told you so.:cheers:" hahaha....

0 being empty, 90 being full

I think you mean 0 is Full, 90 is Empty

You are correct, trying to eat lunch and type at the same time did not work.

Jumper the wires and see if the gauge reads full scale, it should! If it does read full scale, that won't mean it's working 100%, but if it doesn't read full scale then it's definitely not working correctly and won't show a full tank regardless of how much fuel is in there.

You have the right number it was superseeded. Was you old gauge off by the same amout? Usually with these seadoos all of the issues are with the float assembly haven't seen many issues with the gauge.

Old gauge never worked.

I see what you're saying... proof by contrapositive.
