I has running my 1992 yamaha 150 precison blend for about 4 hours without problems between 2500-3500 rpms. I had about 10 gallons of gas in the tank. I stopped and got about 10 gallons of gas. About 10 miles later my boat stated to drop RPM's. I ran it up to 4000 rpms for 20 mins, started to slow down to come up to the dock, the motor was running bad and then shut off started back up 10 mins later. got in safely.
Got home and she runs fine on the muffs.

called yamaha service and he says that the mix of ethonal and regular gas causes the fuel to gel. he said that the idle jets are larger then fast jets that is why she idles okay on muffs.

Should I drain all the gas 10 gallons or just keep the RPM's low while on the water.

thanks
