Go to the Engine FAQs Forum, MNH. Do "Outboard won't start".

Let us know what you find.

check spark, do a forum search on home made spark tester, test compression. the 20 dollar wally world gauge will be ok. if spark and compression are ok fix the fuel system.
I dont reccomend spraying fuel down the throat of a non running outboard.
not only can you easily flood it or possibly hydrolock it. visit a burn ward.
careful testing is always faster and easier that splatter gunning.

i am getting fuel to the engine, and it still will not fire. I have also put new spark plugs in the engine. What next?

Is there a kill switch on this model SeaPro? could it be that I may have hit this switch? Where can I find this switch? I have another question. If I take the spark plug out and lay it on the motor and I do not see a spark, where do I go from there?

is the motor in neutral? the engine will not turn over in gear.

is the safety lanyard attached to the kill switch? this would prevent spark

I do not have a lanyard. It was in neutral when I tried to start it.

Re: 98 75 yahama will not start

I have checked the kill switch but can not check it because now my fly wheel will not turn when i try to start the engine. I have a charger on the battery at the time. What could be wrong with my fly wheel?
