at 18 hours my 200 sho had a oil level appox. 4 inches high. i was just looking over the engine with the cowling off and wanted to see how the throttle operated. had wife to push hot foot down and my wot position was not align with static position on side of motor. way to far open. i adjusted the hot foot stop position to align marks properly. changed oil and filter next day, now have 51 hours and no oil level change. maybe just a coincidence but something to look at for owners having this problem.
