Carburator gum up during storage

"1990 Yamaha 115 HP,only used

"1990 Yamaha 115 HP,only used in fresh water & very low hrs. Don't get to use as often as I would like. Between usage sits up in inside building storage, the carbs are always gumed up when get it out to use. Sometimes 4-6 months between use. Will crank good, but will not perform in water. Bogs when you try to gain speed. I have used two of the major brands of gasoline additive. I have to have carbs rebuilt (cleaned) each time out, to the tume of $200 to $300. QUESTION Is there a better way to prevent and can I clean myself?? }}Whats envolved? Thanks, JHC"

"You may have to have your car

"You may have to have your carbs cleaned one more time by someone who knows what they're doing. From then on use Sta-Bil or Seafoam all the time, double up the dosage when you're going to store motor for several weeks/months. right before you store motor drain each carb with 10MM brass drain plug on bottom side of carb. before you put each plug back in, pump the bulb to "flush" carb out a bit, replace plugs and you're set to go. I know this works because I've been doing it this way for 10+years and my carbs have never been cleaned. Also, get a water/fuel seperator at Walmart for $25, install on your transom and you'll eliminate most of fuel related problems. Good Luck!"

I use the best gas I can buy.

I use the best gas I can buy. Nothing below 93 oct. I have never had a gummed up carb.
