2002 till motor on a 20 Skiff. Motor runs fine and smooth until I go over a wake and hit it hard. It then loses power and eventually dies. Then it takes a while to restart. Once it starts it wants to die when put into gear. Once it is in gear it has 1/2 the power at full throttle. I tried tilting motor up and let it sit for 5min and putting down and back into water. I then starts fine for a short time and then loses power again. Anybody have any suggestions?
