Have an 02 225 h.o. that when I first start it up the whistle and light come on saying no oil. Turn the key off and restart the motor and then everything is fine. Sometimes after traveling a mile to 3 miles, the whistle and light come on again, and I have to shut the motor off and then restart and everything is fine. I live up in Minnesota and it started happening a couple of months ago, and now that its getting cold (Yeah we fish even though its only 30 degrees) it is happening more often. Talked to the dealer and he said it's probably a pressure switch or something in the computer that would have to be reloaded in order to tell the motor that's its cold out so up the pressure to pump the oil. Any one else had this problem and or some other ideas? Thanks for your time and effort. Brent
