I went out this am to do some exploring and a little fishing. Due to a ton of things going on lately I haven't used the boat in about 2 or 3 months but she started right up and ran fine all morning. I get home and put the motor in a cut open 55 gal drum of water to flush her out as I normally do. She'll attempt to turn over but she won't fire up almost like it isn't getting any spark. I checked all the electrical connections but all seemed OK. I even tried using the pull cord but no go. Any ideas?
