1998 Evinrude 130hp V4. Took my son out boating today. Backed up to the water started fine but stalled while I was in reverse. Turn back on but died again. Tied up on the dock. Engine turns over continuously but won't start. Checked fuel line and was not clogged. Removed spark plugs and they were fouled. Cleaned them, dried them out. Seems like I am not getting spark. On my way to get my multimeter. First time dealing with boat engine. Any suggestions will be greatly appreciated.
