Re: 1989 yamaha 8hp
The fuel tank, hoses, filters and carb should be drained(drain plug on carb), and flushed, then filled with fresh gas/oil mix.. Inspect, clean or new spark plug, check/change oil in lower unit. Probably time for a new water pump kit, but you could go ahead and run the motor and look for stream of water from tell-tale. Order the pump kit now and put it on later. She should start right up! Good Luck!
