Recently serviced a 10 yr old Yamaha F9.9 JMH L 4 stroke tiller handle which was mostly used in fresh water prior to us buying it, and for the past month using it in saltwater. I've got the following parts :- Cylinder gasket not changed Carb repair kit - parts replaced. Water Pump repair kit - impeller and gasket replaced. Fuel Pump - replaced Water Tube - not replaced Spark Plugs - both spark plugs replaced Engine Oil - changed Gear Oil - changed Oil pump gasket - not changed. Now the issue is, hardly I run it for an hour or two continously, and then run it on idle, it switches off, and refuses to start for the next 20 to 30 mins. Can't quite figure what the issue is. Can anyone help.
