Must be the day for senders you'll pay about $20 less if you go here, http://www.isspro.com/categories.php and if you call them they'll give you all the answers you need.

Well, I found out if the Gas Guage reads FULL, and you go back to the sending unit and UNPLUG it, that if the GUAGE Drops to EMPTY, the Guage should be fine, and the sending unit is Broken.

2nd TEST:

If you use a jumper to the 2 wires going to the guage, and the guage goes from EMPTY to FULL, then the Guage is working.

There is a foam float inside the sending unit that will swell and get stuck. Take it our, sand it down and it will buy you some time, but the unit is on it's way out 9 outta 10. Make sure not to lose the magnets in the foam float

Thanks Flipper! I filled up yesterday on the way home not thinking about sending unit...So I will be "Forced" to take the boat out but once again and use up most of the gas...

I did find out that the current installed OEM product is from MOELLER MARINE. the Part Number is 395-060 Unfortunately, when i called, their computer system was down.

Is there any reason, I wouldn't want to go with them, or is Skidim better?

I called ISSPRO, and they said that their unit is different and I woul have to take it apart and get length from origional unit...

Not sure if they still supply MC with senders but they were standard in all MC's and my original one was stamped isspro, but then that was for a 98 PS.

Maristar-Man...where did you end up purchasing this unit from? I need a replacement and can't find anyone open to tell me what part number it is or where I could order it from. Thanks.

Hey Hog, Just gettin back into town. We were at Lake Tulloch, but in answer to your questions...

You will have to remove the old sender and measure how far your sending unit tube sticks into your tank, and possibly cut the new one to be an exact match. Then count the number of wires on the old unit and match the new. Go here and call these guys up and let them know what you have. http://www.skidim.com/products.asp?dept=1088 Phone / (803) 345-0996

It's pretty simple with those two facts in hand. Oh lastly, make sure you don't use any electrical devices or battery operated screw-guns near tank. Just the hand held screwdriver, or you might not need a sending unit after all...

I'm still having trouble identifying the part that I need. My sending unit looks like it only has 2 wires and there is no float involved. It only has a silver tube approx 9.75 in. long. Do you guys with similar models know which route I should take to get a good replacement?

Here's a picture of the unit

I also found this thread which looks like a picture of the unit I have, but no final reply was ever posted to know if Jeff used the Centroid product as his solution.

Sounds like your 99 is just like our 98 Maristar one. Ours looks similar on top, is a two-wire unit, and has an aluminum tube like yours. The float is inside. If you tip is back and forth, you can hear and feel the float rise and fall. Our problem ended up being a magnet that had come loose from the float. Very common. I took the unit apart, found the magnet, glued it back on the float with epoxy, and it has been working fine ever since. I believe there were numbers on mine, where I could call somewhere like skidim and have them help me with a replacement part.
