90 hp mercury

[targaboat938]

My 03 engine starts quickly after sitting over night. However, after running and then sitting on the lake for a couple of hours, it does not start easily and when it does it smokes a lot for 5 seconds. The smoke is white to grey in color. What it the problem. It did this all last summer.
