I tried to self winterize my 2009 40 HP E-tec 2 seasons ago and the motor seemed to self winterize but would not turn itself off. Out of frustration I stored the boat in a heated garage for the winter and ran during the 2020 season. The boat started fine but smoked a lot, especially at higher rpm but a hot sensort never came on or the motor never entered a protective mode indicating over heating. I winterized at the end of the season and this time the self winterization completed with shutdown. Is it possible the motor ran the entire season of 2020 in a winterization mode? It started fine but smoked way more in 2020 than any other season. Not sure if I need to take in and have serviced or not.
