Sorry for putting this in General Forum but I'm working on the boat as I type.<br /><br />I am winterizing my 1983 120 hp I/O Mercruiser and want to change my gear drive oil but can't find a drain or hole to put it in.<br /><br />Can anyone tell me where the drain and fill hole are? Does it use engine oil from the motor?<br /><br />Thanks!<br /><br />Barry
