Fuel load in the surf.

[Crab]

Does the amount of fuel you guy's have in the tank affect your riding in the surf? It seems to have a great influence on my boats if I am running a full load, or perhaps down to just a couple of gallons, I really notice the change.

2 gallons fuel = 16 pounds
5 gallons fuel = 40 pounds

The amount of fuel a ski carries does affect the ride.:wink:

Yeah my 3d sucks ass in the surf when I put gas in it.

I can't say I really notice on my sj. My loosening up probably has more to do with it than fuel level.

There isn't all that much diff on my SJ. I have mine setup for bottom/mid and the added bottom end kick makes up for the added fuel. However, in choppy conditions with less than 3 gallons I can airate the gas lines if ridding at WOT.

In flatwater, I can feel a difference in how I can throw it around. Runs best with 1/2 tank!

Exactly how I feel, I like the full load to eliminate airating the fuel, but 1/2 or less for the feel of the boat. I always run on reserve to minimize the fuel problem. I can't tell you how many times I thought I had an engine issue, when it was just air in the fuel.

2 gallons fuel = 16 pounds
5 gallons fuel = 40 pounds

thats water @ about 8 lbs per gallon.

fuel is roughly 6 lbs per gallon depending on temperture and elevation.

same theory though.:biggthumpup:

I don't like more than 2/3 tank, any more and you can stuff the nose too easily while on a face. That's where Tubbies would help dramatically I imagine.

Definately agree. I feel a pretty big difference when I have a full tank versus an almost empty one. Re-entries seem to be easier with a full tank.

I have thought about trying a smaller tank, perhaps from a 550 to help with the airing issue and lower center of gravity. Re-fueling more often for freerides won't bother me.

crab,

You may want to look into this for your fuel system:

I haven't personally tried it but in theory, it works (with 1 negative effect).

I don't get it, re-entries requires "technique" and if a full tank of gas changes the center balance, just adjust your technique. Sure Tubbies will make things easier, but a simple shift in body position will too (on re-entries). I don't run Tubbies mostly because I don't see whats so tuff about adjusting ones technique to the current conditions...It will make you a more rounded rider (instead of relying on help aides).

I would still love to try some out tho

isn't the only negatiive affect, when you run out of gas you ARE COMPLETLY OUT of gas ??

Yes (but more to this). With one of these installed on a surf/freestyle standup, there are many times when the hull is completely sideways, causing a big air burp into the feed line possibly killing the motor when you need it the most (like after landing sideways from a jump and needing to get away before the next swell eats you up). Basically this "Air-Fuel Separator" kit is kinda like converting to a fuel bowl style carburator (or a stiffening capacitor in a stereo system).

On a sitdown this negative effect would be extremely rare but I often have my SJ 90 degrees to the water.

I still plan on trying one of these kits.

The only time you would get air into your fuel line is when it's time to go refuel anyways .

I think that this thing is a good idea, I would rather just run out of gas rather than risk a seized piston. Does anyone know if the setup shown is for single or dual carbs?
