My starter on my 1990 90hp Johnson is was acting up last season. When you turn the key the motor will turn 1-2 cranks then nothing. release the key and try again and it will begin to turn the motor over like normal. This happens every time the moter has cooled down and is restarted. The Battery is brand new and was replaced after the starter began acting up. Same issues after replacing battery. All cables look clean with no corrision. Do I just need to buy a new Starter?
