Well my boat has ran good for 2 years straight. Never had any problems with it other than normal maintenance. I had it out yesterday to catch some crappie. It was the last night i planned on having it out until March or April. I was heading back to the dock. I had it wide open and all of a sudden it lost power. Didnt make any distinct noises or anything. It just went from about 30 mph to 10. It revs up just fine. Anyone know what it could be? Its a 1991 60 HP Mariner. Buddy of mine had a problem like this and it was a coil? Any help would be great guys! Not in a big hurry, just want to get it fixed for next season. Thanks!
