Good morning all. I have a multiple questions regarding a Merc fully restored I just purchased. serial number 6033659 cant find a conclusive year online yet.

Questions.
1. year ? 2. harness is an 8 pin plus 4 wires ( grey = ? ) ( purple = ? ) ( black yellow stripe = ?) ( yellow red stripe = ? ) ( brown stripe blue = ? ) and yellow black stripe.
Assuming red positive and black ground.
external 4 wires blue white stripe and green white stripe I believe is trim up and down and brown white stripe and brown electric choke? I'm not sure if this 1980's has electric choke? one of the previous owners got ride of the dual fuel / oil tank and was mixing directly into one tank and from what I found so far online a specific procedure should be done at the mechanic fuel pump on the engine and seems to me original no bypass of any sort. this engine considering the year would it have sensors for all the gauges I recieved with it? Tachometer / Volts / oil psi / temperature alarm buzzer? I thank all who take the time to help with above questions I'm sure will have a few more :)

The decals are for the 1976 model year.----What HP is this motor ?-----No chokes , as it appears to have an enricher unit.---serial # makes it 1985 for a 175 or 1982 for 200 HP near as I can tell.

gray= tach sender wire
purple= switched 12v power
black/yellow= kill circuit
yellow/red= starter circuit
brown/blue= temp gauge
yellow/black= choke/enrichner circuit

these colors stand for all merc wiring i know from at least 1980 up.. they have never changed as for as i know..........

its a 1982 200.............. put a "0" (06033659) as first number for serial number and it should show up on most parts sites....
