You are correct , I have not filled the tank with fuel , and now it only has 1/3 in it ,but the gauge only just read off empty.

I thought these senders just changed their resistance as per the position of the float .

If the sender is 2" off the bottom of the tank it will never register fuel on the gauge until the float starts to lift above 2",unless I am missing something .
how many gallons/liters before it hits the float?

also - when you hit "E" you know you really need gas, mine is the same way - plus I never let it get less than a 1/4 tank - not many fueling stations on my river..

If you look inside your tank you will see that there is a box inside the tank. The box is rectangular and can be removed via the rectangular hatch where you removed the sender. Your sender doesn't reach the bottom of the tank and neither does your fuel pickup. They reach the bottom of that box.

The sender has 8 little mercury switches that change when the magnet is above them. Your fuel gauge should change in 1/8 increments. (F, 7/8, 3/4, 5/8, 1/2, 3/8, 1/4, 1/8, E) Any resistance on the negative wire/contacts or lower voltage on the positive will result in lower readings at the gauge. While the sending unit is out of the boat, move the float up and down and watch your gauge.

Play around with it a bit, and make sure your connections are good as is your voltage.

Good luck.

Fuel tank sender unit

Thanks Guys

I think I have found the answer ,
the tank depth I have is 12" ,
the sender unit currently fitted is 10" ,
on the Skidim site it advises to use a 11" sender with a 12" tank.

So I think the i need a 11" sender .

Hello Mike

Re the ISC , please see the image ,(new part is the top one).
They look exactly the same and I am sure I did find a cross reference for the AC51 to the OE one .

What do you think ?

thanks

Kevin

AC495 looks closer to the original - not sure what the difference is - but the stepping may not be the same... also the valve head on the ac495 is completely round - unlike the ac51 - could make a difference in how much air comes in... maybe someone else will chime in,

Thanks Mike

I will run the engine again over the week and disconnect the ISC to see what the idle does then .
Also will post a vid of it running , as the surging is a slow rpm change , maybe I am missing something completely different .

Surging at idle usually indicates too much air running my IAC - as I understand it - did some digging around... it's possible your new part is malfunctioning. Where you able to give a bit more RPM and see how it ran - by pulling the transmission lockout knob?

Hello Mike

re the ISC , the AC495 does cross reference to a part number 17059602 which I can buy over here ,
ebay item number 261138198406.

Are you reasonably happy that the AC495 is the correct number and furthermore does this cross reference look good .

many thanks


Kevin

Now I am not sure... doing some more checking. there are many IAC that look exactly alike but have different part numbers. I believe your IAC is wrong and the one I gave may be wrong too. I want to find the right cross reference to have on file. Indmar probably had used the LT1 IAC for those years but there are two of them...

www.skidim.com has the correct one.... but it's a bit pricey.
