I am buying a 1997 Quantum fish n ski. It has a 1997 Mercury 120 Force engine. The boat starts up fine, but when in neutral, it sometimes dies. The owner told me that it just need to get the idle tuned-up and an overall tune-up of the engine. <br />When in neutral and you give it some gas, it will stay running. When in neutral and not getting fed, it dies. Is there anything I should worry about before I buy it?<br /><br />Thanks.
