Here's what its doing guys, it ran fine Thursday afternoon and all day Friday, went out Saturday morning in tournament it ran fine to where we fished, got ready to come in for the weigh in and it wouldn't start. It will turn over but not start, Iv'e checked the kill switch, oil level is fine, it's got fire to the plugs, ive tracked the fuel lines to the injectors, I can turn it over and it sprays fuel out the injectors but it still will not start. It's got me puzzled and I hope it is something small. I got new plugs today but wasn't able to try them yet.

Choke off? Doesn't make sense it ran fine and then nothing. I've had to unhook gas line and no choke it for several minutes to get one to fire when it's been flooded, but sounds like yours is a spark plug deal. If not that I've had water get into all those lines and the motor not crank. They had to drain everything. 4 strokes have lots more places to drain from my little knowledge

Any chance you have bad fuel?

search here: Yamaha Outboard Forum - Yamaha Outboard Parts Forum.

there are several great guys here that WILL help you fix it.

Sounds like water to n the gas. You try starter fluid?

You might have a clogged are bad oxygen sensor . Easy to replace and sometimes clean . Yamaha engines must have ring free added to fuel to cut down on carbon build in cylinder walls . and like mentioned before bad gas ect can cause problems .
