I just picked up my new to me 2000 38 Fountain Lightning. No Owners manual and I was looking for a few answers. Here are the questions I have for now.
1. 525sc's what gear oil in supercharger?
2. There are 2 fuel tanks. Is there a switch to pull from one or the other or do they pull from both at same time?
3. Where is the fresh water fill for sink and fresh water wash?

Should be like my 2000.... one tank per motor. No crossover or switches, just a ball valve in the bilge to turn each one off. The fresh water fill on mine is a hose connection on the port side of the bilge just below the sunpad hinge.

Size of tanks? I have found fresh fill.
How fast is she with the 500 efi's?
Anybody on the supercharger gear oil? I heard you could use the Quicksilver HP gear lube SAE90??

I don't think the size of the tanks would be different but, mine are 100 gal each. I can't remember what year the size of the steps changed, mine are the larger. twin semi-stagger 525's 88-89 MPH.
don't have blowers so, not sure about the oil. I would contact TEAGUE about that.

I use the NEO/Bravo shop outdrive oil (75w90MRHD) in my Blowers. The service manual for my B&M 250s recommended 80-90w gear lube.

Here is a link to the Fountain service manuals:

Download the manual. My fresh water fill on my 29 is on the port side in the engine compartment. There is a garden hose fitting near the top and the water resevoir sits right below it.

Not sue on exact weight but I used amsoil gear oil in mine

Where's the pics ?

Here is a pic. I'll get more later.

Where is the fresh water drain and where is the grey water holding tank and drain?
