Dropped off my pontoon boat in the lake, started up the motor and moved the boat to the dock. Went back a week later and the motor will not start. The oil pressure light does not come on either. Horn and electric anchor work. Looked at the fuse next to the battery, looked good, but replaced it with the spare. There are 5 other fuses located on the inside of the center console. They all look good. Not sure where to go next, without have to pull boat out of the water. Any ideas?
