I am currently having some problems with my 1996 40hp evinrude 2 stroke. First off: it is shaking alot on idle, Secondly: when I don't feed it a little throttle while it is idling it will shut off. Just recently I launched the boat and started the motor and as I was setting up my fishing gear (allowing the motor to warm up a bit) , I suddenly heard the motor make like a flooding noise, and within seconds it shut off and didn't want to start again. The alternator turned over and all, but no go. I took it in, and the mechanic said it may be the vro pump. Does this sound like the problem? That pump is $350+ and I don't really want to replace it if I don't have to. Thanks in advance guys.
