Motor Identification


I purchased a boat - an alpine tri hull the motor on it is a 85hp Johnson model number 85ESL69E serial number J3034142 the cover says Johnson 85hp hydro-electric drive, could you please tell me the year of this motor and if it is electric shift or if it has an alternator. Iím pretty new to boating - handy with a wrench and willing to learn. 

Thanks Matt



The motor is a 1969 and has a relatively small alternator. 9 amps if memory serves. I was only 7 years old then, so I am not too knowledgeable on the older stuff.
