Boat won't start
So fogged the engine when I winterized it. Went out today to fire it up on muffs and it started up pretty easy. 2006 Merc 350 with TKS (Turn Key Start). I bumped the RPM's to about 1000 and let it run for a minute or so then went to kick the RPM back down and it stalled out. Now I can't get it to start back up. It fires but dies right back out. My batteries have been in it for a few weeks and are reading 12.2 volts with my volt meter so they are low. I'm thinking either my batteries were too low and at a low RPM my alternator wasn't putting out enough? Or maybe that my plugs need replaced because of the fogging oil? But it did run for 2 or 3 minutes before that and sounded fine?
Went to O'Reillys tonight and bought new plugs. No idea how old these ones are.
Thoughts? Temps never went over about 120* and oil pressure was about 50-60 psi. Oil was changed before winter and was checked before starting it.
