I am purchasing a 1996 Johnson 112SP. The hour meter indicates that the motor has 350 hours. Is that amount of hours high for the year of the motor? Is there any reccommended maintance schedule based on the number of hours a motor has?<br />The motor is very clean and the last compretion check was 125 on each cylinder when the motor was winterized at the end of last season.<br /><br />Thanks
