Yamaha outboard problem

[phiboyy13]

Got a yamaha 225 4 stroke that doesn't want to start. Motor is in neutral and and kill switch is in but the weird thing is the motor wont even crank. Everything is plugged in and right when i turn the key an alarm goes off for about 2 to 3 seconds and turns off! Batteries good because motor is able to trim up and down like normal. Anyone happens to know what could be the problem???

Had it been on charge? I've been able to trim up n down before and not been able to start bc of battery. Won't even turn over? Or it won't fire.

Check the charge on the battery as stated above , them 4 stroke yamahas need a full charged battery.

possible a blown fuse under the cowling

Also check the contacts going to the battery. Check for the simple things before you dump any money into it. Ex: gotta be something electrical or fuel related. If you haven't ran it in a while check the fuel like for kinks and where it connects to motor. Sometimes the ball check will stick. Then go from battery to key switch to motor trying to find loose connections and blown fuses etc... It's a 4stroke I'm pretty sure u gotta have a certain amount of voltage for then to start. I know optimax do for sure. Found that out the hard way.

I tried everything. But its the alarm thats got me confused! Haha! Right at the turn of the key and it's goes off for 3 seconds and silent and turn to the off position and does some kind of clicking.

Take ur cowling off and get someone to stand at the engine and listen to c if the electronic fuel pump is kicking on when you turn the key to on position. After your alarm goes off does it blink in any kind of sequence?

Maybe the throttle position sensor, send Montauk a PM!

Kill switches go bad too.

Let me know if you need parts...Ive got a 2010 sitting at my shop for parts...all the electronics look good under the cowling...its got bad crank bearings in the block and one head sold already.

Did you check kill switch?

[phiboyy13]

bingo!!!! The alarm was set off by the kill switch! but motor still doesnt want to start. brand new battery and check all connections, motor in neutral and fuel pump turns on. anything else that will cause a motor not to crank?

A broken ground somewhere. I had that issue once. Finally got my engine started but then I was unable to turn it off. Had to unplug fuel line and let it die. Finally found broken ground strap.

starter fuse or relay possibly??

We could go threw a list of things it could be. Could be the neutral safety switch inside the control box.
