I have a problem and require the experts advice again! Last week I put my Yam 115 back on the trailer running perfectly. When I launched it today it ran perfectly for 20min and then ran as though it was starved of fuel for the remainder of the day of either on either of my two tanks. On the river bank I removed and cleaned the carbs and put them back together, I also examined my rubber hoses. When I examined my fuel I found no particles, however a white liquid was in the bottom of the tank when I empted it. I refilled one tank with new fuel from a different station and ran it again, however this did not make a difference.
All out of ideas any help would be great. I had water in my tanks before and its is the very same problem however no water is getting in any-more. Also no air is getting in either pure fuel only.
