I have an optimax motor that has been great. Its about 7 years old and I took it out for the first time this year Saturday. I fired up fine on the muffs and I dropped it in the water and it ran fine to our first spot. I was running up the river and I started getting the 4 beep alarm, the one that stands for water in the fuel or low oil. I had just filled the oil up but I noticed two small misses as idle, very slight, but other than that it ran great. I had just filled my gas tank up and I run gas treatment in there year around. Is there a way to save the tank of gas since there is about 18 gallons in there. Would you guys just pump the gas out to be safe? This gas hasnt been run in about 5 months
