Yesterday I decided I was going fishing. It was 8 degrees outside in the morning. I got out on the water and dropped the trolling motor in the water and started fishing. My hydraulic jackplate wouldn't move after about 30 minutes of fishing tried again and it started working. I started my outboard and let it idle for a few minutes, when I got up on plane the no oil alarm went off and the motor died. There was no knocking of pinging noises. Gave it a few minutes and started it back up and took off again. I got no alarm, but was running around 3500 RPM and the RPM dropped on its own to about 2000 and started running alittle rough so I shut it down again. After another hour of fishing or so I tried again and it ran beautiful the rest of the day. I was getting pleanty of water pressure, I was seeing plenty of smoke coming from the water and could smell the 2 cycle. Was it just too cold and the oil was too thick? Can your oil pump freeze? I have never seen this before on this boat, but I have also never had it out in that cold of temperatures.
