Need Help...Just brought the new (to us) SX190 home and I we have bad gas in the tank

[FLBulldogger]

We just got the boat home and after a sea trial that was less that perfect (fuel issues) I need to know how to drain the boat of all available gas (separated from sitting too long in the FL sun)....Please any available advice is appreciated! After about 20 mins. on the water the boat ran great we spent another 1.5 hrs on the water just to insure that it was a fuel issue, I know that the fuel will separate again and need to drain the tank..about 22 gallons and start anew. Just don't know how or where to begin.

Sorry to hear of your initial troubles. I believe an internal screen or something prevents a simple siphon tube down the filler. How much gas is actually in the tank? If a partial tank, you could possibly use treatments and fresh gas to dilute contaminants and successfully run it all through in a nice long familiarization cruise. Then an oil change and new plugs would be good if you don't know the last time they were done. I am not sure about your boat model; but if I couldn't get down the fill tube on mine I would pull the floor, disconnect the fill tube at the tank and use a fluid pump to get it into 5 gallon gas cans. Others may have much better advice.

Is this on your 2017?

That sucks... i am not sure if your boat has a top over the fuel hatch or not but ig u can get to the fuel pumps and remove the sending units u would have easy access to the fuel.

I would put some fuel treatment and seafoam in it and run it out. Would probably take about an hour running hard.

Ditto , Seafoam or Stabil and run it out

Sucks about the gas but congratulations on your "new" boat!

I like the Stabil360. Add some fresh gas and fuel injector detergent cleaners and run it WOT!

Thanks everyone for the help! I used 1 bottle of ISO HEET and let it do its magic for 24 hrs. Started her up this morning and WOW what a difference! No sputter, no surges, nice steady idle hold at 3000-5000 rpm. Then I added 5 gallons of NO Ethanol gas, and the engine ran flawless, even the Wife noticed! Again thanks one and all for the help you all make it so less stressful on us noobs!
Now onto installing a Garmin 44Cv gps/fishfinder and trying to decide on the @Leojay or @xzm2jc method. All I am looking for is an accurate depth indication.and gps position..not a fishing guy.

I'm assuming that's a typo and your idle is not 3-5k . Glad to hear the boat is running goo now and no surging.

@haknslash yep a BIG typo we ran the boat at High Idle for 3 to 5 minutes.. Repeated today and she did great! Finished up the GPS/Fishfinder install and after 4 hours GPS is great and the Sonar works great.
