2012 Yamaha 212SS one engine dead, fuse box hunt!

[g3mh3art]

my buddy just tried to fire up his 2012 Yamaha 212SS for the season, and he's got a problem. one engine roars to life, but the other one does absolutely nothing, not even a crank.

The engines both share the same batteries, so he's thinking it's gotta be a fuse.

I'm trying to help him, I've been staring at the owner's manual diagram, but having a super hard time figuring out where the fuse box actually is.

I think there's a 10A fuse in there somewhere that's messing things up, and the manual vaguely says "in ignition coil holder."

Anyone out there with experience on these boats, can you point me in the right direction for that fuse box? we'd really appreciate any help

That's annoying! On your Yamaha 212SS, the 10A fuse is hidden in the ignition coil holder by the engine's spark plugs. It's small, so grab a flashlight. Check this fuse first, as it could cut power to one engine only. Also, look for any wire damage or loose spots from the battery to the coils

so, the ignition coil holder is a good clue for that 10A fuse.
On many Yamahas, there's a small, sometimes weatherproof, fuse holder right near the ignition coils themselves.
It's often for the ignition system's main power. It might be tucked away, possibly under a plastic cover or near the engine's main harness

You may need to double-check the cleanout hatch switches. If they're not latched properly, it can prevent cranking altogether

@g3mh3art sounds like you’re on the right track with that 10A fuse in the ignition coil holder. Make sure to get a good look with a flashlight. Sometimes it’s tucked under a little plastic cover. While you’re at it, check the wiring from the battery to the coils and any cleanout hatch switches just to rule out other causes for the dead engine.
