Motor was running fine, had a short in the clutch wire which was killing the motor, fixed that run for about another 30 min no problems, pulled the boat up on a sandbar for about 2 hours to ski with some friends and get ready to leave and the motor will not crank. It's getting fuel for sure. I've checked everything i can think of including low oil pressure switch, kill switch, wiring etc... I'm not getting any fire to either plug. I run fresh water only, it's an 06 31hp with carb, heads & exhaust with electric trim. Any ideas?? I'm about to pull my hair out!!

Kill lanyard

If you checked all those things...it could be your coils have gone bad. I just had to replace mine after they got all corroded, and the motor died on me. Def a possibility if your not getting any spark

Never mind, fixed it! The low oil pressure sensor wire had a bad place in it where it is zip tied to the intake manifold and was shorting the system out.
