went out for a short windless cruise. Water was flat, no wind, on my way back at full throttle I suddenly notice smoke pouring out my dorade vents. the whole cabin was filled up with white(I think)smoke. Temp light came on and oil light came on but went off after I throttled back. After reducing the rpm's the smoke went away and I was able to motor into my slip no problem. I am just worried about what it was? I did just hose down the boat real good last night and probably sprayed water in the tank vent(did not know what it was till now). I am hoping to go back out later today. What steps should I take to see what the problem was/is?
