I have a 1998 yamaha 90 hp out
I have a 1998 yamaha 90 hp outboard(mixing oil and gas together in the tank 50:1). The engine has been trouble free and is in very good condition--recently she has been idleing }extremely rough in nuetral and also while engaged at trolling speed runs roughly and vibrates a bit more then normal(At least I think so)but she doe's start well everytime and operates at higher speeds nicely!!!!I am planning to add a fuel additive to burn any old crap out of the engine and the fuel tank and then I will change the spark plugs and the fuel and or air filters....."Any thoughts are welcome"!!!!!(gratefulhooker)}
