1990 40hp evinrude started and runs but after turned off won't start again

[Jhohman5]

I have a 1990 40hp evinrude that I unhooked the VRO to get rid of the ringing and mix gas 50:1 ratio. The engine starts right up when I put it in the water but after running for a few minutes to a few hours I go to start it up and it won't start. I was running the boat down the river at a low speed and the engine just quit. After about 15 minutes or more and trying to continually trying to start the engine it started up and ran like nothing was wrong. The primer bulb was nice and hard when I tried to restart it so I know gas is getting to the engine. I replaced the spark plugs last summer and all fluids are full and fresh. Thanks for the help!

Check your spark when it won't start. It should jump a 7/16" open air gap on a tester.

I'm not sure how to test the spark. I have never done this kind of stuff before. I talked to some people at work and they believe it could be a bad starter solenoid?

So are you saying it will not turn over with they ?----Will not start ?-----You need to be clear on what is happening.----Could also be bad connections / bad wiring / problem with nuetral switch in the control box ?

So it starts cold just fine however after its warm it won't start for 15-30minutes. I turn the key and it just try's to start but I'm not getting the engine to actually start. Just here the nah nah nah sound trying to start up

Take the starter apart for inspection.

If the motor turns over okay and won't start then like I said check your spark.
