SN 200 Fuel tank - how low can you go?

[FMSKI]

Out on a great evening set today, lake was flat, minimal wind and other boats. Started at 10% fuel and came back on 0%
I took 10 liters with me.

On my modded TSC I could see what was in the tank at all times, which as great. Only had 40L capacity too.
The 200 tank is opaque and I have no idea. So how low is 0% crossover point - anyone know?

You are brave FMSKI . I start getting anxiety at 25%, so I'm hoping to never know the answer to your question.

I can tell you from personal experience that when you can hear the FCC humming, its time to shut her down!!!

We try to ski with tank levels around a 1/3 down to an 1/8 just to keep the boat light. Once the dash gauge gets lower than that, my reward to risk meter inverts and I start looking for fuel.

We ran out of gas twice this season. I don't know about the 200, but I hate the L-shaped tank on our 2002. There is no chance for an accurate gauge reading unless the tank is full. I used to say that as long as the gauge moves when we accelerate we were okay, but that back-fired on me. Fortunately, we live on a relatively small lake and we were not far from the house when it happened.

I wonder if the boats have a fuel pump in the tank? If they do keeping enough fuel in the tank helps to keep the pump cool to provide longer life and when you run a tank dry more likely to such in junk in the tank that will foul the fuel filter.

You guys are way more daring than I am.

I believe the OP's boat should have the pumps outside the tank as most, but know that many cars used to or still have pumps in the tank and that is a good reason, to help keep them cool. The high pressure one though, (I think that's the one) is inside the FCC which keeps it cool). I would be careful about always running low as you can pick up junk that settles in the tank, if it has a low pick up... I have seen this in cars awhile back. I try to never go below 1/4 tank. I mean a gallon of fuel is about 7#... 3-4 gallons of fuel makes 30# or less weight difference.

The 200 tank seems to have a bit of well from what I can see. It looks like the tank is a good design. I've got 10L spare fuel under the bow at the moment. So far have not run out.

But my Catanium manifold looks like it might have a crack brewing, left side by the O2 sensor. There is evidence of a former leak. But the lake it was in is high ppm of particulates, might have self-sealed!

The 200 is running great at the moment but... IDK used boats you never know. Worst case have to drop in a new motor

The big fuel filter would not prevent the crap in the tank from moving to the engine?

@Kenboat A friend's MasterCraft with an in-tank pump has had a few failures as he always runs it low on fuel.

I’ve had mine in the low single digits, did not enjoy that trip at all!

Depending on the boat, there may be a basic filter between the tank and pump, then there in one inside the FCC. Stuff can still pass... Over time you would be surprised.
