Hi I need a little help. I have a mercury 90hp 3cly 2stroke with a serial # 0D252840 that I can't find anywhere on the other charts to find what year it is. That and the last time I had it out on the lake it ran good but once it ran for a while after I turned it off it wouldn't start up again unless u wait for like 40 mins or so. If yall have any ideas I would greatly appreciate it.
